I just today upgraded to Windows 11 using the save apps and files option. Now I notice several times that Firefox occasionally crashes to a white, then black screen which requires me to log back into my windows account. Is this a known issue?

TB not responding when opened, cannot click on anything, only a blue circle turning. Tried all kinds of options to resolve this, like start up in safe mode, startup without connected to internet, without windows defender, uninstall and re install. I have no clue what to do next as finding another email program..

I am trying to enter my Thunderbird account to review my emails, however, everytime I click on the Thunder bird icon nothing happens. Please help me to regain my ability to open Thunderbird. I am falling wat behind in my work.

I've been using Thunderbird for years. I shutdown my computer (MacOS Sequoia) and went away for a few days, and now Thunderbird hangs when I try to use it. I have one main email account which I access with POP, and a couple of other accounts which I access with IMAP. I can access the downloaded messages in the Inbox of the POP account that I downloaded before going away, but I can't read any other folders (I have many folders since I've used Thunderbird for so long), or access the IMAP accounts. Thunderbird shows that I have new mail waiting on the POP server, but it hangs when I try to download them. It does not show mail waiting on the IMAP accounts, although I know new mail is there.

I have tried re-installing Thunderbird, and rebooted the computer, with no change. When Thunderbird hangs, it eats memory until the system runs out, and I have to use Force Quit to terminate it.

It's the first time I've had a problem with it!

I have recently started getting the message "Gah Your tab just crashed" when using firefox W11 lenovo laptop Up to date with updates Started yesterday (26/2) Happens most of the time now Seem OK on another laptop

Program keeps crashing on startup. This has been happening for a week or so but it would load second time. Now won't load up at all. I have reinstalled but to no avail

I recently transferred my email account to The Messaging Company (big mistake I think) because my provider (Exetel) suggested them when they stopped hosting an email service. I then started having trouble receiving emails that I knew were sent and I thought that maybe my old emails were kept on the server too long and were taking up too much space on the server so I went into Thunderbird to change the settings to delete emails that had been on the server for 2 weeks. Thunderbird is now locked onto the Account Settings page and I can't get out of it. As soon as I click on the page I get the "Thunderbird not responding" message so I close the program. I've tried starting Thunderbird in safe mode with no result. I downloaded the latest version and reinstalled Thunderbird but as soon as I start the program it takes me straight into the "frozen" Account Settings page that I can't get out of. I have gone into The Profiles folder and I've included a screenshot of what's there. The latest profile was created when I tried to change the Account Settings. Can I delete that profile and go back to the one created on 9/6/2025?

Hello, I synced all my gmails to thunderbird (many). When I tried to archived some messages, I found they are in my main inbox. The all mail folder does not contain them. I am trying to restore allmail to contain everything. Thunderbird keeps crashing, it seems like it is crushed by the load of my messages. Further, the archived messages are now missing from my gmail account. Please help! Thank you, Steve

Today TB started Not Responding (freezing up).

What I've done so far: -Reinstalled TB -Updated Windows drivers -Started TB in safe mode -Started Windows in safe mode -Created an exclusion for TB in my Avast anti virus

None of these made a difference.

What else can I try?

Hello,

I have today encountered a reproducible issue with Firefox 145.0.2 (64-bit) on my system (CachyOS Linux). Whenever I press the "Print" button in the printing dialog for a PDF file, the browser freezes and no longer reacts to anything. I had to kill the process manually and try again. I have then downloaded the PDF and opened a different application to print it - that worked fine. Is this a known issue with Firefox? Does anyone have an idea how to fix this?

I already tried resetting the printer settings in the browser, but that did not change anything.

Thanks, Stefan

Hello, I have ran into issues with the file upload window in firefox locking the program. I am not quite sure if I have tried uploading anything since the last update a few days ago, but it happens regardless of the website I use. It basically just freezes up as soon as it opens the file explorer window. I tried on chrome with no issues so it doesn't seem to be a windows thing as far as I can tell. I restarted my pc to see if that would help, but with no luck. I opened up task manager when this was happening to check what was going on and firefox seemed to be stuck using almost all the ram on my system 15.7 out of 16gb.

Anyone have this issue occurring in the last few days? Any thoughts on how to fix?

Thanks for any help

I must have changed something because T'Bird no longer starts. I was trying to copy TB file from Win 10 to a Win 11 PC. That failed because some files could not be copied. But now TB is not starting up. I checked the Start folder and it is in there.

Suggestions please.

My computer glitched today. Before that I could bring up Firefox and all pages would restore.

Now Firefox comes up and shows one page like a new page. One tab and no other pages appear I had several open when the incident occurred.

Now I get the one page. From the Task Manager window I see the one page and "crashhelper" followed by several Firefox icons (all appearing to be using memory) but none of them are displaying any pages on my display.

I made a screen shot and enclosed below

My question is about lack of functionality (Topic) but it is not listed in the selections above!

I selected Accessibility because I cannot access any of the tasks shown below the "crashhelper" because none of these pages are displyed

For over 1 week now I am finding that T-Bird freezes or locks after I have opened several messages. Leaves me unable to read or delete messages and unable to close down T-bird

A number of times during the day, when I'm on my email account a window interrupts me to verify my account ( photo attached) After I follow all prompts repeatedly over many times a strange series of slashes cross the top of my window and it asks me if I want to go back to my previous last email. I can not proceed with my activity. So I close the computer and wait a couple of hours and try to start up, BUT my password box is filled with dots. I am unable to continue. So I wait longer. When I do get access it all starts over again. Is this you or google doing this? I have been with Thunderbird for years, and I hate the idea of having to go through Google to use you. Yesterday it locked me out of my computer in total. Need help!

When I login to amazon, it asks my user name (normal), then asks my password (normal), then when it sends a code to my phone, it freezes the entire browser and I have to force quit Firefox. Been happening a week, I've cleared history, run several programs (Malwarebytes and CCleaner-with normal results) and restarted my computer (Macbook Air running Sequoia 15.6.1). Any fix for this?

The browser constantly crashes to desktop, it constantly loses passwords and has to be reinstalled and for some reason the developers chose to make it download images in the webp format which iOS doesn’t render properly so images are always blurry, and they also chose to give the user no way to change that stupid decision by the devs. Are you ever going to add the about:config option so that the users can at least make the adjustments the devs refuse to make?

My thunderbird email repeatedly keeps crashing after being open for about 5 minutes or so. Time after time for the past 4-5 days. I have sent reports each and every time but the problem persists .can you please help me I will have no choice but to cancel my account and donation. Thank youbold text
