back to article Mozilla tells extension developers to get ready to finally go mobile

At long last, Mozilla is planning to make browser extensions, also known as add-ons, available for Firefox on Android, at some point following the expected November 21 release of the browser's version 120 build. This week, the organization urged developers to evaluate their extension code in preparation for the occasion, since …

    I don't use Firefox on mobile because... well, there's no point without my extensions and other browsers have ad-blocking built in.

    If I can use uBlock Origin (and my other must-haves) on FF mobile suddenly I'm interested.

      I've been using fennec, a Firefox build from the f-droid store, for the last year or so. It has extensions enabled (as well as a bunch of telemetry disabled) and runs ublock without issue. Turns out it's just a feature flag and the only thing stopping Mozilla from enabling it was their own reluctance to do so.

        Mozilla's Firefox Android version already supports uBlock Origin (and a limited list about 20 other extensions), so you don't need to install F-Droid's Fennec to install uBlock Origin. This Mozilla announcement is about allowing users to install extensions that aren't on that list.

          Unless I'm part of some A/B testing, they already allow everyone to re-enable the extensions that were disabled a few years back. I think this change happened 3-4 major versions ago.

          I've had uBlock Origin and NoScript running on Firefox + Android since it was announced. Very useful.

      I had to double check phone - I've been running FF (standard channel and beta) for almost a year now with ublock and noscript. None of them has been installed through F-droid. I'd not use Chrome for regular web browsing.

        I'd not use Chrome.

      I've been using the specified add-on for ages. I'd rather not add all the others I use on desktop because I'd be leary of FF slowing down on the phone.

    What % of mobile users actually use Firefox?

    I'll live without it until it supports zoom and reflow (See Opera).

    Especially as my eyesight is starting to deteriorate.

      To be fair, Opera is the only browser supporting text reflow. Chrome also doesn't have it.

      Atlas Browser used to have that on Android - an excellent browser that sadly stopped being developed and is now obsolete. I still miss it. One-click disablement of Javascript from the main screen being a leading feature, along with the built-in adblock.

      uBlock on FF Android is ok, as is the Crystal adblock on the Samsung browser, which I actually like too. However, only FF seems to still allow YouTube streaming with the screen locked.

    To get ready?

    I've already seen new add ons for mobile this week and even installed a couple.

    And Chrome can now kiss my grits.

    I've been using extensions in a custom addon collection through Firefox nightly for ages, had no idea the vanilla browser was so far behind.

      Mobile? Becasue I've been waiting for FF mobile to enable add-in for security and it's seems they finally done it, whereas early this year, there were no add ons.

    Too little too late

    Firefox's market share has completely evaporated on mobile. I've jumped ship when they disallowed everything but a handful of extensions years ago, and would definitely think twice before coming back.

    Unfortunately there is no API parity it seems, for example "History Cleaner" (a 'recommended' extension) doesn't work on Android because the history API is inaccessible.

    I can confirm that Ublock origin has been an available add on for Firefox for Android for at least a couple of years it was the main reason I installed Firefox on my phone in the first place. But I will look to see if the containers add on is available and working for the mobile version as that is a very handy extension i used on Firefox on my PC.

    I wish they'd restore options as well

    Whenever I return to Firefox on Android, it reloads my tabs (sometimes failing if I have no Internet access). I understand this tab unloading could be disabled in earlier versions, but this option no longer exists.
