I have a backup.bak file.

My computer was re-set and I lost everything.

How can I restore my new downloaded Thunderbird, using this backup.bak file.

Thanks.

When I had my internet provider help me change the ports so I could set up thunderbird, some of my email and folders were automatically imported from Outlook. But I cannot see most of them. If I try to create a new folder from the top level (above inbox), I can see ALL my folders to choose from, but I can't when in the inbox. Why and how do I change this. I am not a techie so I can't understand answers that aren't broken into simple steps.

I am able to save tabs to collections. However, there is no collections section on my homescreen, despite support articles and questions indicating it should just be there. When I turn shortcuts and stories on, they still do not appear. How do I make collections show up?

Most of the questions I have are either not answered at all or not answered in help or in forums and I'm unaware of any responses to questions I've asked. Isn't there any way to get support from a live person? My questions are often quite complicated. When I ask a question, I get dozens of answers that have nothing at all to do with my question and I don't have time to look thru all the answers. When I do see an answer that might be relevant, it either isn't or the answer is far too technical.

For example, I have no sent folder. Cant understand answers that tell how to create one. Need to be able to save my sent messages. Having to cc myself to get a copy of a sent message - stupid situation.

I am switching from Outlook to Thunderbird because of complicated problem with Outlook. Got garbage when imported csv contact file and can't find how to delete a large number of contacts. Reluctant to use your specific Outlook import in case it brings the Outlook problems along.

Really need help with lots of things making the transition. 'bold text'

Mozzila не открывает предыдущую сессию, соответствующая галочка в настройках стоит. Я пробовал разные способы, указанные в часто задаваемых вопросах. В том числе с подменой данных в папке sessionstore-backups: запускал браузер - находил эту папку - вставлял нужный файл .jsonlz4 - перезапускал браузер. В таком случае все мои вкладке были на месте НО после закрытия-открытия браузера сессия снова сбрасывается. При очистке браузера, появлялась кнопка "восстановить предыдущие вкладки", восстановление происходило, НО закрыл-открыл браузер - и снова пусто. Пробовал удалить браузер и установить снова - та же проблема. После запуска, если открыть журнал - в разделе недавно закрытые вкладки, недавняя история поиска - пусто, как будто предыдущей сессии вообще не было. Как исправить эту проблему? Примечание - мои закладки, введённые пароли и расширения на месте.

My (our) ISP started using new 'bigger/better' software. grrr

The ISP's tech support had me close (? delete ?) my Thunderbird e-mail account & start a new one.

I cannot access - use any of the ?17-19? folders. How do I, if I can, recover the folders so I can start moving relevant messages to them?

Good luck, remain WELL & be SAFE!

THANKS!

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?

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.
