Even though I have settings set to load previous tabs when Firefox is started up but when it is restarted it doesn't load the tabs. This has only occurred the last few days. My solution is to select "reopen all windows" which does what I want but also opens several other versions of Firefox. Noteworthy, confusing, but probably not associated: In the course of trying to work through this, I have had a baseball playing on Chrome. I ended up closing out Chrome but the baseball game audio continues even though the Chrome appears to be closed on the taskbar.

Out of a sudden all of my bookmarks were lost. I tried importing bookmarks i had previously saved in an HTML. Did NOT work. I tried "revert to older date bookmarks." Did NOT work. I tried "import from another browser."Did NOT work. Funny thing is that with the same HTML file i extracted from mozilla when i made a copy a couple of weeks before, i was able to upload all bookmarks to Opera but not to Mozilla!!!! The image below for the non Greeks reads "Failure to process copy document".

I am having a problem with a 502 Bad Gateway error which will not go away. There was originally a real problem, but it has been cleared up. I am trying to access an e-book on Libby from my local library site when the error occurs. The link works without any problem in Microsoft Edge. It used to work in Firefox as well, until the temporary problem occurred. I have clear my Firefox cache, but this has not resolved the problem. Somewhere Firefox has stored something which is creating this spurious error, but I have been unable to find it. Any suggestions would be very much appreciated.

I've installed Thunderbird on new computer, and moved over from the old computer emails and Address Books (including customized ones). But when I start a new message, I can't get any e-addresses to appear in the To box.

What do I need to do to access Addresses?

HERE'S HOW I SOLVED THIS "SECURE CONNECTION FAILED" ISSUE:

Kept getting this error when attempting to update Firefox; didn't matter which browser I used; went through the forum postings and tried every this-and-that-and-this-and-that posted there; didn't work; finally --

i opened a $10.00 30-day hotspot account with Xfinity, and the download worked perfectly.

PROBLEM SOLVED.

Thunderbird being used as IMAP client for Gmail - with no issues, until recently when an existing email recipient, who sits behind the Barracuda Networks system, fails to receive mail from Thunderbird's recent versions because it is rejected and blocked by Barracuda. I have tried using plain text formats and checked that SMTP server accounts are correct all to no avail, a 550 blocked is the result. The Thunderbird ver is 143 64 bit - However mail from an earlier 32 bit version 115.5 was successfully delivered, later 32 bit ver 140 failed to deliver through the Barracuda system.

Email from Google's own Web client gets delivered and mail from the Android mobile phone app likewise arrives. A simpler IMAP client (MailSpring) manages to get mail thru Barracuda so what has Thunderbird done to appear a threat to Barracuda ? BTW Mailspring is sort of 'Ok' - but it just isn't Thunderbird - it was installed only as a test vehicle !

Hello! Today I stuck with problem in my system: after minor package update, hardware acceleration was broke. In past, I stuck with same problem after total pc upgrade (AMD -> NVIDIA GPU, another might be unnecesary), and somehow I fixed it, but i dont remember what exactly fixed it. Can someone please help me turn hardware acceleration on this time? My searching the key arround didn`t helped, but i found in about:support line which notes that firefox unrecognized my videocard etc. My specs: kernel: 6.17.1-zen1-1-zen driver: nvidia-dkms-580.95.05-1 videocard: GTX 1080 TI DE: gnome 49 with Wayland

Steps that i have tried: Tried to make all as wrote in archwiki Tried to install an nvidia vaapi implementor Made some random steps from internet, without effect(maybe thats why hardware acceleration doesent work??)

theres also about:support page attached

I have an iMac and it will not log into our credit union's web site. When I goo to the log in and enter my password and such, and click on log in, nothing happens. I have a Mac Book Air with Firefox on it and it works fine. So does my wife's laptop. But my iMac doe snot work. I can use Safari to log in but not Firefox. Very annoying since I use Firefox all the time.

My c: disk is getting full, so I decided to transfer my Thunderbird profile to d: . My old Tbird profile has profile folders for two POP accounts and two IMAP accounts. I managed to copy the profile and set up new accounts and now emails work, but in the process I disconnected the old profile on c: . When trying to create a new account on c: (so that I can access the old profile to delete old mails and get more space) I run into either "incoming server already exists" or I am asked a password which I can't find.

Any help would be highly appreciated! Should I just delete the old profile, or is there a procedure to safely remove it? Or is a Tbird reinstall in order? Thanks!

Running Firefox 140.3.1 ESR on Debian, lately I've been experiencing a bug when I have several instances of Firefox open, and multiple tabs open in each instance. After a few minutes of browsing and opening and closing tabs, I am unable to drag tabs to rearrange them (above the address bar). The "X" that is part of the tab also doesn't work to close the tab, and clicking the main "hamburger" menu icon (three horizontal lines) does not drop down the menu. If I switch to a different instance of Firefox that is already running, sometimes the "hamburger" menu icon starts working (sometimes not), and I am able to exit and restart Firefox, which works for awhile, and then a few minutes later the same thing happens again. Interestingly, when it's not working, I am still able to "right-click" on the tab and choose "close tab" from the drop-down menu.

I've been trying to discern a pattern, but have not been able to find a way to reliably reproduce the error. It often seems to happen when I'm using Reddit or Craigslist (maybe only more noticable because I often open and close a lot of tabs on those two sites). At one point I thought it might be related to opening a new tab for a site that had previously been opened in another Firefox window (instance), but that may be a false lead, because I haven't been able to find a way to consistently trigger the bug.

Thank you for maintaining the best privacy-respecting browser in the world, an indispensable tool for me.

Hi I recently received an update on Windows 11 insider channel that blocked me from using Firefox and Google Chrome. It also refused to allow me to reinstall Firefox. It would not let open the browsers at all. I did everything possible-no child restrictions- no security issues-no issues with Microsoft redistributable packages. The only browser it would allow me to use was Explorer. I ended up doing a clean install of Windows 11 to fix the problem. I don’t think blocking a user from a web browser is legal but I’m not a lawyer. Thanks, Jonathan

I have over 17,000 emails in my inbox and Thunderbird won't let me send any more out. I tried to cull blocks of emails (e.g., all before 2024) but it wouldn't let me do that; it made me do one at a time.

Is there no way I can delete a whole lot in one go? SW

My bookmarks, history and passwords have disappeared. I looked at the articles, refreshed firefox, have restarted firefox and my computer multiple times but cannot retrieve them.

This is the message when I start firefox

The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

Hello- Wondering how to turn off the "skip to main content" that continually pops-up on some web sites. This is a problem on a single Firefox installation and I cannot figure out which setting this could be.

Thanks in advance! -BD
