I have had message filters set up for a long time. Recently I tried to make some changes (adding one filter, deleting others, changing the response). I find that if I close Thunderbird and reopen it, all my changes are gone! How can I get the filter changes to stick?

Hello, today firefox has been appearing as a blank icon on my taskbar. I have tried solutions suggested in older posts but it did not help unfortunately. if i try to

1- right click unpin from taskbar the icon shows once more. 2- right click, the icon disappears/becomes blank. 3- click pin to taskbar, the icon remains blank.

attached is the image showing the steps i described above

TB no longer will start. It just hangs and when I go to it on my Mac I see a spinning disk. That never changes and eventually, after hours, I must force quit and report it to Apple. I receive no messages or error codes.

I lost power to my PC when Thunderbird was running (thanks electrician who tripped the whole fusebox!). Since then despite everything I have tried Thunderbird will not open my mailbox. I get the screen 'Set Up Your Existing Email Address' shown in the screenshot. I can see my address book.

I have tried creating a new profile, copying across all the data from the profile in use until yesterday and changing the profiles.ini to point to the new profile. If I start using the profile manager (thunderbird -p) it shows the new profile but if I click it then I still get the same screen shown in the screenshot.

After looking at other support pages I tried deleting the .lock files and rebooting, still the same.

Under the troubleshooting information I can see the correct profile folder and open it, if I click about::profiles then the correct profile is in use.

It is a bit more complicated as I had the profile on a NAS drive but I have created a new profile on the PC and copied all the data in the profile directory to the local profile folder. Still the same results.

Edited: After trying a couple of other things - import into a new profile from the currant one, still same results, and changing the installs.ini file to match the profiles.ini one, also same results, I have uploaded a couple more pictures after looking again at other support questions.

I am on version 115.10.1 (32-bit)

Thanks for any help.

I have several email addresses all on my own website and all with identical setup at the server end. I just added two new ones to TB and they vanish when TB restarts. I've installed them a couple of times, they auto install perfectly, but they keep vanishing.

I've checked that all the mail servers and ports etc are the same as on the ones that work OK. So I'm assuming that the problem is some kind of generic problem with cache / profile corruption etc etc. Assuming that is the case, what kind of generic cleanup fixes should I try please?

Many thanks.

Nvidia RTX Super Resolution seems to only work very rarely or not at all compared to the Chrome version. In some instances it will upscale the Full-Screen Video. It will not interact with windowed videos at all. But it will never upscale a windowed version that exceeds the playback resolution.

Steps to reproduce for windowed videos:

1. Open any youtube video
2. Set the resolution to 480p or lower (as I am using a QHD 2560 x 1440p monitor)
3. Playback the video and monitor Nvidia Control Panel to see if Super Resolution has activated.

Observation for windowed videos: Feature works in Chrome. Feature does not work in Firefox

Full-Screen and Super Resolution: I have no idea what is going on here, on very rare occasions it does work, for the most part it does not work at all. If I had to give a rough idea of when it works, I would say that it is more likely to work when Firefox has been freshly launched.

I could neither see an active change in the Control Panel, or notice anything in the video quality. Both a quality change and feedback in the Control Panel occur when using the feature in Chrome. I have tested on identical links, with identical quality settings.

I tried:

• setting the Super Resolution Quality manually, instead of manually
• an incognito tab

I recently updated to 125.0.1 and now get 'failed to check for updates': - when I manually check (help > about Firefox) (see image) - in 'settings' it also shows 'failed to check for updates' (see image) I never had such a problem with previous versions; any suggestions?

Hyperlink insertion only works in troubleshoot modes but not in main mode even if all extensions and hardware acceleration are turned off (used this guide: https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird#w_the-problem-no-longer-happens-in-troubleshoot-mode)

Please help me.

Thank you!

I upgraded to Thunderbird 115.10.0 (x64) earlier today and now the program is no longer closing completely (I've tried using the X at the top right of the window, and I've also tried File menu -> Exit). I first discovered this when I was using CCleaner to clean my temporary items and it asked me if I wanted to close Thunderbird after I had already closed it. I then checked my running processes and there are three Thunderbird processes that remain after the program has supposedy closed (Task Manager screenshot attached).

Any help with this seemingly new bug is greatly appreciated!

Much thanks, -Snipe

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

I just switched to Windows 10 from Windows 7. Firefox was working fine, but now many or most pages are garbled; see screen-capture fragments at http://www.fenichel.net/firefox/. I tried a new Firefox 64-bit, but it crashed on most pages.

Using the arm64 version of Firefox on a Surface Pro X causes several graphical issues. These issues started either with a update of Firefox or drivers.

This topic has already been reported, please see here for more information and documentation: Reddit: https://www.reddit.com/r/firefox/comments/182iojx/firefox_arm64_graphical_problems_on_surface_pro_x/ Mozilla Connect: https://connect.mozilla.org/t5/discussions/firefox-arm64-graphical-problems-on-surface-pro-x/m-p/52086

What can be done to report this issue and help it getting fixed?

When I print an email, TB prints all of this technical jargon such as X-MS-Exchange lines, and what seems to be the background handshake protocols behind the email. I just want the contents of the email printed. May I ask how I fix this, please?

Hello Good People,

I noticed that the snap version of Firefox had a lag issue when typing into input field. For example, when composing an email and wanting to use backspace to quickly delete a misspelled word, then backspace works slowly, stuttering and jittering. If I hold down a key in the input field it also lays the character down in a stuttery, slow way.

I tried reinstalling the system and that solved the issue. But it has returned again. Maybe it was an update. I also installed WINE and waybridge to get some windows plugins to work on my DAW. I don't know if that has affected it.

I also tried removing the snap version and installing firefox using the terminal but the problem persisted.

It's an annoying problem. Any advice appreciated.

Just recently Firefox seems to have its downloads capped at 15-16 meg speedtests show the full 1Gig speed OPERA AND EDGE both download at the full 999 megs but firefox has recently stopped downloading any faster then 19 meg

what in firefox could be causing this its not happening in any other browser.

Ever since the update, I have had pink flickers on videos on youtube and twitter. They last for less then a second, so I couldn't grab a screenshot of it. After doing some reading online, I turned off hardware acceleration which turned the pink flicker black and now effects several sections of the web browser.

I updated Thunderbird to the latest version and now I have a problem that continues to remain after closing the process.

Thunderbird 115.10.0 64bit (Build ID 20240412173147) OS Windows_NT 10.0 22631
