Firefox 153 contains itself while Thunderbird 153 fixes almost everything

Mozilla released Firefox 153 on Tuesday, closely followed by MZLA with Thunderbird 153 – codenamed "Meadow" for reasons that remain obscure for now. Firefox 153 is Mozilla's new Extended Support Release (ESR), so it will receive security updates until some time after the next ESR in mid-2027. We covered the highlights of what's …

Why stop at tabs?

I’m wondering how many people will like the separate container approach so much they will eventually end up using Qubes OS.

> Qubes OS.

Very clever, but looks very inefficient in its approach to me.

I would prefer microVMs:

And that they were diskless:

Re: Why stop at tabs?

Efficiency is a fair point.

Though Qubes OS’s primary function is security not efficiency.

Those Qubes (containers) are seriously isolated from each other

From your first link…… “LXC containers start instantly, share the host kernel, and are spectacularly efficient. But they’re not isolated – a kernel exploit in one container compromises everything.”

Compromise one Qube and the rest are fine. Well, so the theory goes anyway.

Read a not further down the first link. :-)

He's describing his home built alternative to LXC. They are full VMs with full isolation.

I'm curious to see

If the bug that insists on dating all my email arrival times USA style has been fixed...

"Works on my machine."

Seriously. All of them, macOS, Linux and Windows.

I think your locale settings are wrong or broken.

Re: I'm curious to see

I think it doesn't like a German locale and a UK keyboard, or possibly, a DE timezone.

Re: I'm curious to see

I'm a strange beast and while I'm Italian, I use a US keyboard and a Denmark language, Denmark time format and day/month names and Italian numbers and currency on my Linux Mint. So dates are in the right format dd/mm/aaaa but language is English, week starts on Monday (Italian style) currency is Euro, decimal is comma, number separator is dot. And Betterbird 140 ESR works and the dates are right.

You are not kidding! :-o

You are a QA tester's dream user.

Thunderbird 153 changes

Try the release notes ...

Re: Thunderbird 153 changes

I did. I included them in the article. They are linked in this sentence:

«

MZLA's Thunderbird messaging client also has a new version, itself an ESR: Thunderbird 153.

»

It's the first one of the section on Thunderbird. I thought that would make it hard to miss.

24H later, I note that neither the FAQ not the "what's new" pages have been fixed.

[Who-me]

"Thunderbird 153 fixes almost everything". Oh no it doesn't! My gmail account worked fine before it updated. Now it keeps telling me authentication failure every other time I open Thunderbird.

Sign out and sign back in again?

Thunderbird is looking good

I have to use Microsoft Outlook at work, and MS keeps making it worse, slower and less reliable. Microsoft seem to test nothing these days.

Thunderbird, just keeps getting better.

I'm at a loss as to why anyone would downvote this but please note you are not reducing my happiness in any way. You did however provide a soupçon of amusement, thus actually improving my overall happiness.

For there last week, X posts seem to be escaping the Facebook container.

I've tried 'open in containerr' > FB but they revert to opening in the default container
