I normally use Fedora but my Fedora machine died yesterday. For a time being I want to use Thunderbird on my Mac.

I have a backup of my thunderbird profile directory from Fedora 42. This corresponds to thunderbird-128.8.0. On the other hand, the current version on the mac is thunderbird-138.0.2.

1. Since the version number is higher on the mac I think I will be able to use the old 128.8.0 profile with the new mac version ?

2. If I do this, I will not be able to transfer my profile back to Fedora when I get it working again (because the version number there is lower) ?

3. Is there a way from me to install thunderbird-128.8.0 on the Mac so that I will be able to transfer my profile back to Fedora ?

(The topic is the closest I could pick from the dropdown.)

After a disaster last October appearing after a macOS update, I have been working to get back to where all is normal. Apple asked me to erase and reinstall macOS. I was using TBird (some struggles) right up to doing the erase. My question:

Is there some data in the backup ups of the profiles that identifies the TBird version that was last using the profile?

This might also help me: is there is some data in the .app files that identifies what version of TBird the Package "file" is for.

Thanks for your help.

Yesterday (Sat 5/31), I woke up to the 139.0.1 update, along with a new behavior that Firefox will hang (and require a Force Quit) any time I click a pinned extension that opens a drop-down interface (e.g. 1Password, Adblock Plus, Pocket).

I've tried disabling all extensions and bringing single ones back (as well as disabling Pocket via about:config) - the result: any extension that opens a dropdown causes the hang, and any extension that runs without opening a dropdown works just fine, regardless of the combination of extensions that are enabled/disabled at the time.

I tried opening Troubleshoot Mode (although it's of little use since my problem seems rooted in extension behavior) - the first several times I tried, it ALSO caused a hang, but now I'm able to turn it on & off without an issue (though the page rendering is wonky within it - I imagine that's just a Troubleshoot Mode thing?). For whatever it's worth, I think the change that preceded it starting to open without hanging was my disabling this [setting] (though it didn't cause any change in the original behavior, which was my initial goal).

I'm running macOS 14.6.1 if it's of any use. Thanks for any troubleshooting ideas!

I think I'm running. Ios v 138.3 Is thatcorrect? Other websites are saying that my Firebox needs to updated. I have been trying where do this. Pls let me know. Thank you

I have exported my theme made in Firefox Color (love it) - both xpi and zip. The theme has been working for 2 weeks. I just want to reinstall it to check, and eliminate Firefox starting with "default" and then loading my theme. I also have no backup if I had a computer malfunction.

I'm not sure how it can be "corrupt" since I'm looking at it working right now. I exported using your site and your buttons - but when I try to install it says "unable to install because it's corrupt."

This app comes with lots and lots of updates, and every time I have to delete the old start icon on the task bar and re-pin it. Please, fix it so that I never have to do that again. There is no other software at all including Mozilla Firefox that does this to me.

I can find the sites I use, this isn't the issue. I want to check I haven't been hacked in some way, which is more of a concern particularly over online banking and internet financial transactions. Thank you for your attention. Stephen

Hello,

I have download and installed the latest version of Firefox, have the following issue click on help on the menu but the following message appears on the screen unable to check for updates, have remove Firefox and install it again but no good.

Any help would be appreciated

Thanks Matthew

Dear Mozilla,

you should be clearer in new Firefox versions about which changes need to be manually enabled or are being rolled out in stages. It’s really frustrating to keep reading about new features and being asked (I have the new version X - according to the news, Y should work...) only to find out that these features either arrive delayed to the end users or need to be activated manually.

And please give the user more choice about whether they want to use new features (for example the "https://" trimming, volume icon in tabs...) and provide an easier option than tinkering with the "userChrome.css".

Thanks and best regards, Martin

I had installed an extension that allowed me to transliterate Cyrillic text. I think it was called Transliterator.

Today I noticed it went completely missing - it's not even listed at the bottom of about:addons as disabled.

What happened to it?

TIA

The latest update to 140.0b2 of the Devloper Edition turned the leters of the side panel to black... On a dark background. Some themes will make the background white and it makes it readable, but a whole bunch off themes (including my prefered ones) have become useless since the last update becaus eof this bug: the letters of the bookmarks in the side-panel are fixed to black. How can this be resolved?
