I try to update Firefox once a month, but every 6 hours I am notified about the release of a new version, so I have to click Cancel. Is it possible to increase this interval (at least to 24 hours) or disable it altogether?

I tried changing settings "app.update.interval" and "app.update.background.interval" but it didn't help.

I just received an update to FF 137 and my userchrome.css which is set to show tabs BELOW the toolbars (i.e. a logical place above the relevant pages and not halfway up the toolbars etc.) has stopped working. Checked the toolkit.legacy etc and it's still enabled.

Any ideas to fix this are welcome.

Can anyone tell me, please, how long I should be able to keep accessing Firefox on a Windows 10 tablet after Microsoft withdraws support for Windows 10 later this year? I seem to remember being able to access the internet on an old laptop as a 'test' a year or two after I'd stopped using it after Microsoft stopped supporting whatever version of Windows was on it, but I can't remember whether it was via Firefox or Internet Explorer or some other Microsoft browser. If Firefox will still 'work' will Microsoft withdrawing support for Windows 10 have any effect on how well it 'works', and/or how secure etc it will be? I am going to try to install some sort of Linux on the tablet (well) before Microsoft abandons Windows, but if it turns out I can't install Linux, I'm hoping I should at least be able to access the internet via Firefox. Thanks to anyone who can help. (ps I'm not sure whether this is the right place to post this question, it's just that performance and connectivity seemed to me [in my ignorance] to be most appropriate!)

Hi!

I installed the Thunderbird app via Play Store a while ago. I have the F-Droid app on my phone, too. I now got a notification from F-Droid offering me an update for Thunderbird. I'm far from a pro. I would have expected an app installed via Play store to only be connected to and updated via Play Store. Is this all safe and okay? There is no Thunderbird update available in Google Play.

Thank you for your help, please let me know if you need any phone specs or version numbers!

What does this mean? being updated by another instance

Is this why my FF is running godawful slow today?

Pages coming up in 20 to 60 seconds or more instead of in a second or two.

Hi, The question is in the title. I have imported my Outlook data in this 32-bits version (updated to 140.7) . I would like to keep them in a 64-bits version (147). I didn't find the solution. Thank you for helping me. Michael.

Could someone please tell me what the latest version of Thunderbird is on the Release Update Channel? I am on version 139.0.2, and when I check for updates in the app, it says that Thunderbird is up-to-date. Is version 140.0 not going to be available on the Release Update Channel?

Hello, I have Mozilla Thunderbird version 128.12.0esr (32-bit) on a Windows 10 laptop On the Help/About Thunderbird it says update failed. I have clicked on download and have version 139.0.2 in my downloads folder. When I try to install it all goes well until I get a message "Your computer must be restarted to complete a previous uninstall of Thunderbird. Do you want to reboot now?

Yes No " I have rebooted several times now with the same results. What do I need to do to get the update Regards Peter Norris

Hi

My version of Thunderbird has just been updated automatically to 140.Oesr (32-bit)

I now cannot enter hyperlinks (Ctrl K) into emails.

The text appears in the email but it is not underlined.

I have also sent the emails to myself and the hyperlink is still not clickable in the received email.

I was able to enter hyperlinks in the previous version of Thunderbird.

I hope you have a solution because I use this facility frequently.

Thank you.

Your latest request for donations has evidently come with a forced upgrade which I did not authorise. I have been happily using an older version of TB because it supports my add-ons and themes. Now because of your uninvited intrusion they no longer work. Furthermore it seems that I can no longer download an older version that supports my requirements. NOT HAPPY!

Since updating to 141.0 64 bit today (Jul 22, 2025) my addon Filtaquilla is disabled.

I tried another attachment saver and the same thing happened. Okay, I'll revert back to previous version.

Can't do that without starting a new profile.

Sure glad I donated to Thunderbird last night.

The latest Firefox release (141) on Android introduced a couple of new features marked as "progressive rollout", e.g. the ability to protect private tabs via PIN, while the release also brought regular updates, e.g. security fixes.

Does someone know how a progressive rollout of such a feature works technically for the userbase? How can a release be rolled out, but some of its features be kept back while other changes apply to all?

For example, the ability to set a PIN for private tabs is a local user preference configuration. The user may or may not have a user sync profile. How is it possible to rollout the feature progressively on the same release channel? Or does the progressive rollout imply the first group of users receive the feature with consecutive minor releases, e.g. release 141.1, the next group with 141.2, etc?
