Bonjour, J'ai essayé à plusieurs reprises d'installer Thunderbird (a chaque fois 1 don est requis) mais à chaque fois le même message s'affiche : "Le profil Thunderbird ne peut être chargé. Il est peut-être manquant ou inaccessible". Une première fois l'installation avait fonctionné mas j'ai essayé de modifier le profil afin qu'ils puissent reprendre le carnet existant sur mon ancien ordinateur. Aujourd'hui je suis bloqué. Avez vous 1 solution à me proposer ? Merci

On my windows 11 machine, Firefox requires me to re-log into my Mozilla account every few days (there is a yellow triangle on the Account extension, which when clicked, has me to log into my Mozilla account). I have tried several troubleshooting steps:

1) Create a new profile and set it as the default profile 2) Completely uninstall and reinstall Firefox using the steps in the following article, including removing user data. https://support.mozilla.org/en-US/kb/uninstall-firefox-from-your-computer

I'm using Firefox on a Mac and my iPhone and I don't experience this issue. I am logged into my account on both devices.

Thanks,

Paolo

It appears Windows 11 KB5065797 broke my Thunderbird. It will not start normally nor will it start in safe mode.

- I've updated to latest version 144.0 - I've tried starting in safe mode - I've tried running as administrator - Thunderbird shows in Processes, and displays suspended randomly - I've restarted Windows - I've cleared cache under users\x\appdata\local\thunderbird\profiles\x\cache2\entries\

Running Surfshark on Windows 10 or 11 and Unbuntu 24.04. Some sites and attachments giving error failures. Happening with Firefox and Edge. Need troubleshoot source.

After the update on the 14th, dark mode has gained weird stylistic choices that I cannot find a way to alter: namely, when closing a new tab, a white box with black font appears -as opposed to the previous darker toned grey/purple with white font. However as of writing this post, I notice that dark mode is not working on this webpage. Seeing as I have an extension enabled in addition to the basic dark mode selection in Firefox settings, I can only imagine that something was broken in the update. Please advise, the change is jarring.

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

This morning, Firefox updated automatically to Firefox 144. However, this update completely broke Firefox; every tab crashed, and I couldn't even use Firefox to get to this help site.

Changing my OS is not an option for me; those decisions are made far, far away. I was allowed to use Firefox instead of Chrome. Sadly, I have to switch over to Chrome today in order to work.  :(

I have added a couple of screenshots.

I am moving over to Chrome to do some work.

Thanks for any help, B

I have WhatsApp Web pinned as a tab in Firefox, and other than that I also have a home page. Normally when I launched Firefox, only one window would open and it would have both the pinned whatsapp tab and the homepage in another tab.

Since today, now when I launch Firefox it opens two separate windows. One window only contains the pinned WhatsApp Web tab, and the other window contains the home page.

How can I make it so that when I launch Firefox only one window opens that contains both tabs? Please don't tell me this option has been inadvertently removed.... Thanks.

I can't open https://english.ahram.org.eg and https://gate.ahram.org.eg/ Someone knows why? Maybe it has something to do with the last update. I think I could open them some time ago. Thanks!

I seem to get really high CPU and memory usage only when I run youtube on Firefox. This issue never happened before. How can I fix this?

I upgraded to Firefox 143.0.4 and lost all of my Bookmarks. How do I find and reload my Default Profile? Also, I cannot load anything in Firefox I am forced to use Edge which I do not like at all!!!!

Just moved to W11 - initially I had to resolve the bookmarks functional error message - done, but I seem to have a long list of items suggesting many bookmark folders - with items that were just links to sites I had been on - and the original bookmarks folder I had created does not now appear?

Following help on here re bookmarks and history system non functionality - I have renamed files and deleted files such as favicons.sqlite etc etc - but that has not resolved any issues.

Not sure that explains it - hope you can help.

HI and thanks for any help.. I am Popping my gmail and several other non-google accounts. It has worked for years but now I can't pop any gmail after 10/10/25. The mail is there when I go to the gmail web page. It is trying to Pop it cause I can see the message on Thunderbird "there are no messages to download" from that account. I checked and there are no filters. I did a test email. It shows up in gmail but won't pop to my PC. all the other non-gmail accounts are working fine with new messages coming in. I checked all the subfolders and nothing there since 10/10. Any ideas? Thanks. Kevin Brand

Hello. I accidentally made multiple copies of one folder and some of its nested folders. I can't move them back because the copy was already found in the main file. How do I remove the duplicates?

I tried to add a new account with PROTON mail and it didn't accept it. Can it be done? Is there a problem? The goal is to have 2 accounts and not just one. Can you fix it?

Hello,

we are currently experiencing high memory usage issues with Firefox on our terminal servers.

Problem description: All employees work within a terminal server environment. When using web applications such as Vimcar (https://fleet.vimcar.com) in Firefox, we observe a very high RAM consumption. A single Firefox tab can consume 2 GB of RAM or more after being open for several hours. As a result, the terminal server becomes slow or unresponsive, and other users on the same server are affected. Since the terminal server allocates resources on demand, a hanging process continues to request memory until it eventually terminates itself, which severely impacts overall system performance.

Questions: 1. Are there settings or configuration options to reduce Firefox’s memory usage in terminal server environments? 2. Are there recommended best practices for running Firefox with memory-intensive web applications on terminal servers? 3. Is it possible to set memory limits per tab or per user session to improve stability?

Thank you very much for your assistance.
