I've been tasked with removing Firefox from all Windows workstations in our enterprise environment. Our users don't have local admin, so when they install Firefox, it is installed in the user's profile.

I've just installed Firefox 143.0.1 in my own user profile for testing purposes. However, when I attempt to uninstall, either from Control Panel or by running %localappdata%\Mozilla Firefox\uninstall\helper.exe manually, UAC prompts for elevation, even though I installed without elevating.

I've dug in a bit more, and I found this was an issue five years ago as well:

According to that post, the issue was resolved, but it seems to have come back.

Any help would be appreciated.

I have a macbook air laptop (late 2010) and have been using the latest version of Firefox browser for browsing. It's one of the few browsers still available. Google is popping up with the message that my browser is no longer supported. Do you have any suggestions about a browser that may work (other than a new computer please)? Will Firefox be coming up with a new extended version that will work? Thanks!

That is the first line in the Hippocratic Oath. All doctors have to swear to it. All software developers should too.

I made the mistake of letting Firefox on KUbuntu update. It obliterated all my tabs and all my history. There's nothing left. I had a lot of tabs open with intent to use them to update some astronomy instructional activities. I don't know if I'll be able to find them again.

I don't really have a question except to ask: What fresh hell is this? Is it really that hard to just leave things the hell alone? I'm afraid to ever update Firefox again. If everything else wasn't based on Chromium, I'd be out of here.

Also, it looks like something out of Windows 7.

It's all gone. It's a wonder you didn't delete all my bookmarks while you were at it.

I created an export .zip from Tbird on my current Win10 PC, intending to import it into a new Tbird installation on my new Win 11 PC. This is the second such migration: I did my own mailboxes no bother last night but this time its my wife's. My pack was less than 2GB, hers is just over.

I unzipped at the target PC, and attmpted the import. It failed with this error: Uncaught (in promise) DOMException: Could not open `C:\Users\marie\AppData\Roaming\Thunderbird\Profiles\39la2kp7.default\prefs.js': file does not exist (NS_ERROR_FILE_NOT_FOUND)

Is there any alternative to demanding even deeper pruning of her archived messages?

Currently on 131.0.3. Started having this issue around the time 131 dropped.

I press Ctrl-shift-O and bookmarks manager won't open. Bookmarks manager opens normally if I use the menu to open it. Keybind won't work in troubleshooting mode so I know it's not an addon, and the hotkey works fine on other computers with Sync enabled so I know it doesn't have to do with my synchronized settings. Also won't open with a fresh profile so I am very hesitant to reset all my settings.

I use this keybind multiple times per browsing session so it has had a major impact on my usage. Not sure what to do. Please help!

I'm going to try a graphics driver update in the hope that helps. This is on Windows btw.

I installed chatgpt, but I've found it more of a nuisance than a help. I've tried on-line to find out how to remove it but none of the suggestions seemed to work. I'm using the latest version of firefox on a Macbook Pro. Any ideas welcome. Charlie

Dear support/community, I'm a little confused on the support of 115 version of thunderbird. It has been kind of treated as a "esr" version, like below 115.16.0esr indicates.

https://archive.mozilla.org/pub/thunderbird/releases/115.16.0esr/

I know firefox is stopping update until end of 1Q 2025, and my assumption that applies to all Mac, Windows and Linux and till then firefox will get high/medium CVE patches if impacted --- is this the right assumption?

I'm not sure about the situation of thunderbird. while I intend to believe similar to firefox, also told that 115.16 is the last 115 version.

Thanks.

the original error was posted 2015 I had the same quite some times no in 2025/2026

"My Firefox is opening in Administrator mode, which prompts me to agree to allow Firefox to make changes to my PC every time I open it up. I read that I needed to go to Properties and deselect all my compatibility settings but this doesn't work. Any suggestions would be greatly appreciated?"

Installed latest version of TB and want to migrate account settings and messages from Postbox to Thunderbird. I used the TB import tool and selected the active Postbox profile to import. All three accounts were imported. All the emails in one account were imported. In the case of the other two accounts, one of which is active and one is inactive, TB only imported the message headers only, not the contents.

I then found a migration app from a software company that was supposedly designed specifically to migrate Postbox accounts and messages to TB. When I ran the app, I got the exact same results as when I did it manually.

Any ideas on why the message content is missing on all emails in the two other accounts? The account settings are unchanged from Postbox.

Thanks!

I am currently running Firefox on desktop (128.4.0esr) version.

The last few addons that I have installed are not working properly. Or rather, they work just fine, but when I close Firefox and re-open it later, they seem to fail to actually enable. I must go to the about:addons page, disable the addon, and then re-enable it for it to actually work. If I do not do this, it will not be on my toolbar, and the Extensions sidebar button does not show the addon in the list. It's as if it isn't properly installed.

After reading this post: https://support.mozilla.org/en-US/que.../1420017 I thought maybe my extensions db got corrupted somehow, so I followed their instructions and deleted the extensions.databaseSchema config. And wouldn't you know it, it worked! Once I restarted Firefox, I saw some notifications in the main sidebar menu and was greeted with this: Notifications Once I clicked through them and enabled, everything seemed fine.

However after closing firefox again, the problem comes back. Those exact extensions that I manually approved upon restarting are the ones that are giving me troubles and not enabling properly. An interesting thing I noticed is that these all seem to be extensions that require additional permissions. I enabled the addon and gave them the permissions they requested, so I don't know why they are failing to enable properly on startup.

I want to permanently fix the problem

This is minor, however, some addons that I need currently only work up to version 138. The version found at Index of /pub/thunderbird/releases/138.0.2/win64/ is actually version 139.x. I was able to download 138.0.1 at Index of /pub/thunderbird/releases/138.0.1/win64/

I have a custom pitch black theme ( pls add it without addons ) which now only flashes for a second when i open the browser and returns to the normal greyish dark mode. When i go to Firefox Color addon page and load it again in saved themes it stays pitchblack even if i open another browser window until i close all the browser windows .
