I tried to use Thunderbird today,.. to find the interface was broken, menus were blank, so no ability to look at anything., and error message inferring there was a menu config issue was all that was shown. I duly removed Thunderbird as a snap install, which took a long time as it seemed to be making a backup to somewhere. I then reinstalled Thunderbird 128.11.0esr (64-bit) on my ubuntu 24.04,.. having setup the isp email credentials,.. all seemed fine,.. I then proceeded to import what I assumed was my old local folders... And this is where things went wrong, as I seem to have lost all my archived 2025 emails,.. I say somewhere,.. as I don't seem to be able to find them, I have used the 'find' command to locate anything with 2025 in the file name,.. but without success. At the moment I have a multi-structured 'local folder' entry, but nothing with 2025 in? I anyone able to shed some light on what I may have done wrong Many tx

pages don't load due to old MAC osx yosemite 10.10.5 downloaded Firefox 115.24.0esr but don't know what to do when wavy arrow from firefox icon to App icon image appearsScreen Shot 2025-06-04 at 02.47.08

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 ?

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
