back to article Rid yourself of Adobe: New Firefox 19.0 gets JAVASCRIPT PDF viewer

Mozilla's Firefox web browser now includes a built-in PDF viewer - allowing users to bin plugins from Adobe and other developers. The move to run third-party PDF file readers out of town comes after security holes were discovered in closed-source add-ons from FoxIt and Adobe. The new built-in document viewer is open source, …

      Yep, since the Foxit issue I've been opening PDF's in Acrobat. Nice to have a light viewer back in the browser, and (naive as this may seem) I trust Mozilla's approach to security much more than Adobe or the maker of a third party reader.

      Also, no speed issues at this end (so far).

          I've configured Acrobat to not allow access to the internet, or use javascript, or media files, etc. If a PDF isn't just an electronic equivalent to a paper document, I don't want to know.

      Question - how does iOS have built-in PDF functionality? Is it a special Adobe plugin baked into the OS, or Apple's bespoke PDF reader app, or what?

      1. jai

        Re: I've been trying it.

        Apple's desktops have long since had native PDF ability. Since 10.2 i think.

        Because of this, not only can you view pdf files with just the system tools, but also makes it very easy for any app to render a pdf doc - hence Safari has been displaying PDFs from the web for years without needing to install a plugin. A nice side effect is that because it's part of the system, any application on a Mac that uses the default Print dialog should be able to print directly to a PDF document instead of a printer.

        So i assume the same Quartz code that is baked into OS X was also included in iOS from the start as well.

      2. ThomH

        Re: I've been trying it. (@JDX)

        The boring historical version is that PostScript was the standard for high end printers so several vendors built desktop platforms around PostScript as the description language for drawing on-screen rather than rolling their own versions of QuickDraw or GDI or whatever — Sun was one (with NeWS), Next Computer was another. PostScript is a full programming language* and when adapting NextStep into OS X Apple looked at the licensing fees for the implementation NextStep had used and decided instead to keep the same primitive drawing semantics but do away with the language.

        Separately, over at Adobe they designed PDF as a record of the output of a PostScript program (so, to spend storage in order to save on complexity, at least initially). So PDF also inherits the same primitive drawing semantics as PostScript.

        That made it easy for Apple to add PDF rendering and print to PDF to its operating system and all applications just work. There's no translation layer whatsoever, the drawing operations are just serialised and stored or deserialised and performed. As iOS is a close relative of OS X, with exactly the same graphics operations and frameworks, the same stuff just naturally carried over.

        The same is not true of Windows because even once they were looking to do something beyond the GDI Microsoft insisted on inventing its own document format in XPS and tied WPF, its modern drawing framework, around that.

        (*) trivia: the original LaserWriter — a key component in the early desktop publishing revolution — had a CPU 50% faster than the Mac it was meant to be attached to because it had to do all that high resolution rasterising.

        Re: I've been trying it.

        Not 100% sure of my facts here but I seem to remember that the Mac OS GUI is pdf native (in other words uses pdf for finder elements) so pdf is in effect part of the OS. I'm guessing... as iOS is a flavour of Mac OSX it also has the same capabilities.

    It seems to work OK - but the character spacing is messed up, '/' characters are too close to whichever one follows, for example.

    I'm not 100% sure it's the Firefox viewer that's to blame (although any affected .pdf displays fine in FoxIt).

      Re: Acceptable

      That may be a font issue - if the font is not embedded in the PDF and not known to the browser, the browser will have to make do with something else, which probably won't kern in exactly the same way.

      Or I might be talking rubbish. :)

        Font issue

        Just tried it, and this is what it's looking like to me... original PDF contains a condensed font, the browser uses my default browser font and tries to kern to the condensed font.

    Am I the only person...

    ..who prefers to open PDF files in an external application rather than scrunched inside the browser window? Haven't used a browser plugin for yonks. I wish there was some simple viewer software that just viewed & didn't support all the JavaScript and other crap that PDF's can now contain tho..

    1. JDX Gold badge

      Re: Am I the only person...

      I find more frustrating that some sites automatically trigger PDF loading in the browser, and others force you to download. I use Chrome and the PDF integration is really good since I don't have to both downloading files.

      I imagine this being a new project, it will be worse than Adobe's version for now but if they have drawn a line in the sand, it will inevitably improve if people report bugs. Not totally convinced JS is the right tool for the job though personally; on a mobile device CPU is a precious resource.

    Mixed blessing

    I just tried the PDF viewer there and while it works the print functionality is a bit crap. Printing appears to render a lossy jpeg snapshot of the page into an HTML page with headers and footers and the whole lot is printed. The font kerning also looks iffy with characters not properly spaced. I hope that future versions improve on this.

    So while it's okay at a pinch to use it's no substitute for a proper PDF viewer. I switched back to the Adobe plugin from the Applications options almost immediately.

      Re: Mixed blessing

      Hmm. That kind of kills it really. PDFs are meant to represent actual "documents" so quite often you need to print them. When you print a PDF it should print exactly as laid out in the PDF - that's one of their major advantages compared with HTML. Not being able to print them properly kind of kills the whole point of PDF. Especially as FF is bad enough at printing web pages - I often get better results telling FF to print to a PDF then printing that from Reader...

      Chrome's PDF printing is also lousy.

        No Tom, the point in having them electronic is that you DON'T have to print them. There are only 2 reasons why you'd print something these days, one if to sign it for a company who don't understand technology, and the other is to send it to someone who doesn't understand technology.

            No, I'm a technical architect and part of my role involves helping companies reduce their reliance on paper. If you can think of more reasons to print a PDF from a web page then go ahead, but don't accuse me of being a student just because you can't work out ways to stop people printing PDFs from the internet in your organisation.

            I feel I need to spell this out to you so I will. I didn't say anything about a paperless office, or reducing printing as a whole. I just said that there are only 2 reasons to print a PDF from the internet and I stand by that.

            I also happen to know lots of ways to reduce overall printing in organisations, not just PDFs, as well as the regulations people often misquote as requiring a paper copy or a signature. Unfortunately for smug forum posters like yourself, that's not what we're talking about here but I'd be glad to help you out if the users your helpdesk supports (you must work on 1st or 2nd line to be so jaded right?) insist on printing everything.

              @Lusty Re: Mixed blessing

              I can give you three very good reasons for printing a document that you haven't mentioned:

              One, a print copy, once made, cannot be modified or altered. The problem with electronic documents is that they can be readily altered and the change erased to suit someone's agenda - for example, to facilitate corruption, fraud or theft, or to rewrite history. This is why many companies (including ours) still maintain filing cabinets with paper records of all meeting minutes, quotes, invoices, and transactions.

              Two, a paper record is human-readable without requiring any machine or power to display it. In the event of a disaster, or even a protracted power outage, paper records can be retrieved, read and acted on even if there's no power for recharging phone or tablet batteries, or running PCs.

              Three, a paper record does not rely on document or media formats that may quickly become obsolete or unreadable. Many records have been lost because they were stored on things like 8" floppy disks, which you can no longer obtain drives for, or in cryptic 70s and 80s file formats that modern spreadsheets and word processors cannot read.

              A paper record has a permanence that cannot be contested in the way an electronic document can. This is why law courts, for one thing, want everything on paper. If, in a trial, you were to try to hand up a tablet with a Word doc on it, the judge would throw it at you. They want solid paper records than can be filed, retained, and retrieved without question or difficulty.

              In the end, it's not about "not understanding technology." It's about understanding the limitations of technology and using it in its place, just as we need to understand that paper copy also has its place and purpose, and for the reasons posited above, will continue to do so for a long time to come.

                  @AC 04:40 Re: @Lusty Mixed blessing

                  I'm not just being contrary here. Lusty didn't mention anything about a paperless office and neither did I, nor did I state or insinuate that he had. As for documents specifically being "from the internet", how does that invalidate my argument? My first point in particular has validity here, since documents on a website can and do change frequently, so printing one out as it was on such-and-such a date is prima facie proof that this was what the document stated on that date. This is especially true of things like ToS and EULA documents where a print copy made before an online change could make or break a court case.

                  Lusty stated that he could think of only two reasons for printing a document, from the internet or otherwise. I added three more reasons to explain why people print out documents. So no, I didn't just feel like disagreeing. I simply articulated the arguments that were most likely to be behind the downvotes he got (none of which are mine, BTW.)

                    Unfortunately all three of your reasons still rest on someone not understanding technology. It's perfectly feasible to take a copy and lock it from being changed in electronic form. Using e-reader style technology will give you a month to get the power back on, even though in reality power outages are generally fixed in minutes and are so local that you could take a bus accross town to recharge your laptop. Finally, PDF is nearly as old as ASCII text documents and it is unlikely to stop being supported any time soon. If you don't move your stuff from your old PC to your new one then there is just no helping you, but the rest of us managed the transition from floppy to zip to CD to DVD to portable hard drive to flash just fine and I see no reason we can't all continue that tradition. Some of us have even managed that with backup tape formats and SAN with business data on - customers would be pretty pissed if I switched off their old storage and told them the information was gone because it was locked to the old format!

                      I also had to get a thousand fliers printed out, to go through doors. I'm not bad at designing them, but don't have the print capability. So I sent them to the printer in a pdf. Using, as you say, the internet.

                      Actually I do understand technology, better than you might think.

                      "Locking" electronics documents from being changed is simply not reliable or trustworthy, not now, not ever. There's not a DRM schema ever invented that hasn't been cracked. Ever heard the adage "What man can make, man can break?" There's no such thing as "uncrackable", and that means any electronic document can be untraceably altered, no matter how secure the DRM snake-oil purveyors claim the locking technique is. I know this because way back in the 80s I was a member of a well-known cracking crew and I've seen firsthand how these guys operate.

                      You obviously don't live in Australia, where power outages, while not that frequent, when they do occur can run to several hours. The longest one I experienced was nearly two days, during the floods in 2005. And travel across town to recharge my laptop? That wouldn't be necessary for paper records, would it? And even in a major natural disaster, paper records can be recovered a lot more readily. Even if they are fire- or flood-damaged, there's still a chance that some of the information can be recovered - which is not true of, say, a fire-damaged thumb drive.

                      I will grant that PDF is not likely to lose support any time soon, but as to old records being lost because of media and format issues, even with the most industrious record-keeping, archives can be forgotten until it's too late. Things turn up in basements and attics that were thought lost years ago and which could answer many unanswered questions. Yes, in most cases people will transfer data to new formats as they become available, but only if they know or remember that it's there. You know, PEBKAC - the human factor!

                      I'm not saying electronic storage is inferior to paper, or that every single thing should be printed out. I'm simply saying that both have their place and their uses.

                Re: @Lusty Mixed blessing

                I think your reasons are too optimstic regarding printed documents and outdated regarding digital documents,

                One: Actually printed documents can be altered: pages wear-out, pages can be tore out, erased, signatures can be forged, etc. In that sense digital documents along with digital signatures are better because they provide evidence of integrity of the data, authenticity and non-repudiation. Advanced digital signatures such as CADES, PADES or XADES are even better because they provide evidence of those qualities for long periods of time which is requiered for documents like contratcs and wills which may be used many years after the signing digital certificates have expired or revoked.

                Two: In the event of a disaster maybe you would be able to find and read your document provided there is enough sun light or a candle at hand. However in case of a flood, fire, tsunami, burglary or earthquake printed documents can be lost forever..

                In the other hand digital documents are easier and cheaper to backup, copy, share, find, transport, store than printed documents... maybe that's the reason because many companys and goberments are tring to digitalize their documentation and get rid of printed documents?

                Three: document readability after long periods of time is a problem even for printed documents which can wear-out and become unreadable. There are standards for digital documents like PDF-A 1a, PDF-A 1b that specifically address that problem even if technology changes (fonts, display technology, programs, formats, etc)

                Four: In many countries there is already legislation in place that allows the use of digital documents along with digital signatures for any porpouse that a printed document may be required, even in law courts. Generally PDF-LTV + PDF-A 1b or XADES-XLT (Office 2007, 2010, Open Office) are the chosen standards.

                Printed documents would not be necessary if the right digital format plus digital signatures were used, for instance PDF-LTV + PDF-A. However I must admit that these technologies are far from being mainstream, even in countries that have been using digital signatures for many years. I think that's because lack of information, complexity and because most people are stuck in the paper and ink culture.

Likewise, not depending on Adobe to read a .pdf. There is always the chance that what Adobe does interacts badly with what your favourite browser does. If it happens now, we know who made the mess,

    I shall wait and see before I switch, I like the promise here, but what will the delivery be like?

    PDFs should 90% of the time be downloaded and saved, THEN opened,

    Best to disable ALL PDF plug-ins in browsers.

    Also for a Server viewing a PDF is the SAME as downloading so it will "use" up your allocation of downloads on each view.

    Can this so called "feature" be turned off?

    PDFs are NOT webpages. They are documents!

      So do people think Firefox should display spreadsheets. Powerpoint, Word, DXF? Display of PDF in browser is just plain stupid.

        "So do people think Firefox should display spreadsheets. Powerpoint, Word, DXF? Display of PDF in browser is just plain stupid."

        Companies and organisations don't tend to hide information on their web pages in those formats so it's not a much of a problem. PDF on the other hand is often abused because normal users can print to it and then copy the PDF into the website. A good example of this is the leisure centre in Wales I visited last week. The price list is a PDF rather than a web page. Why would I want a permanent copy (i.e. download) of this when I only need the information for 5 minutes? With a browser plugin I don't need to save a copy, then read it by opening up a separate app, then delete the file and reopen the browser.

        Am I just plain stupid, or can I just imagine more scenarios than you can?

    I scrapped Adobe years ago

    I use Foxit

    I ALWAYS explicitly save the PDF first.

    You realise that even with an Integrated viewer the PDF is STILL "downloaded" as far as the Server and your connection usage?

    I seriously hope this is optional and can be turned off. Really I only want to view WEB pages in a Browser, you know HTML..

      Re: I scrapped Adobe years ago

      I can confirm for you it absolutely IS optional. It's just another option in the 'applications' setting. I disabled it because I, like you, download all PDFs to open in foxit.

      I since have uninstalled ff 19 and rolled back to 18.0.2 because of a stability issue, but that could've been my weird usage of firefox yesterday (cat pictures make up 40% of the internet yknow).

      Beer, because it goes well with cat.

    Always listen to an experienced Windows PDF file user?

    I remember the stuff I used to do (such as download, scan with AV, disconnect pootah from tinternet, open PDF with fingers krost... ) when using windows

    So, trades one set of Adobe security headaches for a set from Larry's Swiss cheese emporium? No thanks!

      For the love of God, JavaScript is not Java.

        Re: Dan 55 Re: JavaScript?

        "For the love of God, JavaScript is not Java." Duh! JavaScript has plenty of security holes of its own. It is the clueless that insist "JavaScript is not Java" that propagate the falsehood that JavaScript is safe simply because it is not Java.

          Re: Dan 55 JavaScript?

          No, it's the clueless that maintain that JavaScript is from Larry's Swiss Cheese Emporium instead of Mitchell's Swiss Cheese Emporium. If you want to make a comment on safety, don't talk about ownership.

          We need a double fail icon.

            "No, it's the clueless that maintain that JavaScript is from Larry's Swiss Cheese Emporium....." JavaScript is a trademark of the Oracle Corporation. I would suggest you leave your "cave" and go join Jack White down the local record store trying to get laid, that should keep you from posting more fail here for quite a while.

            "......We need a double fail icon." I would suggest a portrait shot of yourself, deep in contemplation, would be a most suitable icon.

                "Here, have a link......." Read this you obtuse moron:

                ".......Have you finished digging or shall I hand you a spade?" Well, take the spade and your head out of your arse and maybe you'd be able to see for yourself.

                BTW, JavaScript was also behind some of the most serious security holes in Firefox:


                So don't try and pretend your fave scripting language is holy and infallible just because you can't see reality from your self-inflicted rectal domain.

    Does it supports forms? properly not...

    I don't really see a point in this

    I tried the FF reader but it's slow and I could only scroll by using the scroll button. I spent almost no time before changing the application option to open Foxit. The FF reader seemed to offer few options.

    Well, unless new Firefox 19.0 also gets the functionality of Creative Suite 6, I won't be rid of Adobe just quite yet...

  22. rogerk

    Had liked Foxit til..

    Nitro PDF, still best for me.

    FF19, to date, no info on what to not to do..

    Just use KDE

    Kde has the fastest .pdf viewer built in.

    It uses next to no resources, its built into the desktop and doesn't have the terrible security bugs that the offical reader does.

    Running Linux may be change my hatred of .pdf's I used to have when running the Mcdonaldsoft OS.

    You see what your knowledge tells you you're seeing

    To all those who have posted comments here, I would urge you to view

    the opening of James Burke's "The Day the Universe Changed" then ask

    yourself how your thoughts will be judged by a computer historian in

    the far future, say 2360. The chances are that we will all be thought

    moronic for our simplistic, self-centred views.

    Note I make this request as someone who has filed a number of PDF

    vulnerabilities, as can be verified by a Google search on "James Quirk CVE."

    I am not, however, a PDF apologist; nor am I a self-publicist.

    My reason for popping up here is to look for volunteers who would be happy to cast

    a critical eye over a multi-resolution PDF I am currently constructing. Said PDF ponders

    what an electronic document should be to support the propagation of computational expertise

    and will be unveiled at a scientific meeting in Seattle, this July.

    Sadly, I can't offer any remuneration. But if you have an inquisitive mind,

    I can offer material which might stimulate your intellectual juices.

    For instance, one experimental PDF has a functioning web-browser embedded

    inside a Mandelbrot set, which in turn is buried inside the eye of a duckrabbit

    who is under the watchful gaze of a Cheshire Cat. And the Cheshire cat

    is buried inside JFK's Moon Speech, and so the madness goes on for a

    10^50 variation in length scale; a multi-scale oddysey that is all squeezed

    into the dot of an "i" on a PDF page.

    Should you wish to learn more, a Google search will throw up my contact details.

    Best regards,
