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?

Why does firefox crash all the time. I can't even get on espn or msn.com. I used to be one of the biggest supporters of firefox Not anymore, it is a horrible useless browser now.

As a long time (more than 15 years) user of Thunderbird application, I regularly update this app on my computers (5 of them) running on MacOS, some on MacOS 10.15.7 and other on 14.7.6. Before the last update to TB 140.0.1esr, I was using the version 128.11.1esr on my computers without any issue. But, following the installation of TB 140.0.1esr on one of my computers running MacOS 10.15.7, I notice a strange behavior of the application: (1) the application was running slower than the previous version, (2) when I try to close the application, I receive the system message that this "application quit unexpectedly", (3) the diagnostic test of my system shows that the CPU time is used at about 35% by the TB application. I had to completely remove the TB 140.0.1esr and painfully reinstall the previous version (128.11.1esr), due to the corrupted user profile! Now the TB 128.11.1esr runs normally and required about 0.3% of CPU time. So it will be imperative to look upon the compatibility of TB 140.0.1esr with MacOS 10.15.7. I did not try to install this update to my Mac M2 machines, following my issues with Mac intel machines. Thanks for any reply, G.Roy

Firefox won't stop. No function. Same time: Firefox won't start. Large # of tabs crashed? Hacking? No clue. New version ? 141.0.1, still crashed.

On Firefox Focus, nearly impossible 2 give info here.

ALL my online stuff is on Firefox! No backup 4 long time.

I had firefox for 5 years it worked great then I upgraded one day about a month ago and NOW I have had to Force Quit firefox 20 out of the last 30 days. engineers ??????????????????

Thunderbird causes blue screen in Windows 11. It's very obvious, since it doesn't happen if I don't open Thunderbird and problem normally occurs when I click on almost anything. It normally takes 2-4 reboots before running properly. It makes me nervous!

is anyone else having issues with this POS browser shutting down unexpectedly FREQUENTLY for NO reason. I thought the first dozen or so times it was updates, but only once or twice there was mention of new feature. I am SO over it and think Chrome with it's risks IS the smarter move

I have been getting this error for about a week - absolutelyu no changes have been made to my usual use of the PC and browser. There may have been Firefox/Windows updates installed. I'm not doing anything different to the usual work I do.

I have tried using a new Firefox profile with no cached info carried over, this doesn't solve the problem. I have no extensions or add ons. I do run Avast, but haven't had this problem before.

NB: I do not usually get the opportunity to submit a crash report when these crashes happen.

Since updating to version 135 all the tabs crash. I've uninstalled\reinstalled, deleted app data, disabled AV and created a new profile. The only time it works is in troubleshooting mode. I've looked at extensions and plugins and I'm only seeing OpenH264 video codec and Widevine content decryption. I've disabled those but still get the crashed tabs.

I'm also not generating any crash logs.

Firefox has been my browser of choice for over 15 years. Recently, it has crashed on me, causing me to lose any work I was doing. At any time, I receive a notice at the top of the page stating that I'm not connected to the internet, accompanied by the Firefox Symbol. I have to restart, and then it holds for a bit before crashing again.

Sorry! 0 results found for ‘Thunderbird locks up when I'm typing an email and says Thunderbird is not responding. Has been going on for a couple of weeks. I'm on Windows 11.’ for ‘Thunderbird’

Thunderbird has been working well for years, but now when I click on the icon it simply drops to the bottom taskbar and refuses to open. I can do nothing with it from there - refuses to do anything but close. I've run antivirus and cleaned up the computer, but no joy with Thunderbird. Thanks for any suggestions.

So, Thunderbird crashed today, and I was writing up a nice Crash Report when the dialog I was typing into vanished! I have no idea if it sent what I was typing (I didn't initiate a "send" [I don't know how "Submit" was languaged, there]).

This is the only way I could find to pass this information on to, hopefully, the developers. I suppose I could hunt for a Bugzilla vehicle, but I'm pretty busy, right now, so you're lucky you're getting this! It took a while to get here!!!

Every time I make Firefox full-screen, it immediately crashes and shuts down. I have restarted the computer, uninstalled and reinstalled Firefox, but it still doesn't work.

Since upgrading to 140.0esr on Thunderbird, client freezes (Windows 11 indicates as "Thunderbird is not responding") for anything from a couple of seconds up to a minute or two whenever downloading emails in the background. This is very annoying, especially when trying to write a new message (or even while commenting here in the Ideas panel). My main account is on a Microsoft Exchange service, so I need to use the OWL add-in but the delays also seem to occur when accessing gmail. The other "feature" which seems to have changed is inbox defaulting to top then running through to end when sorted with most recent at bottom. I have now reversed to have most recent on top, which seems to have resolved, but this was also annoying. Attempted to resolve by clearing 1 GB from cache and archiving about 15K conversations - but interruptions not significantly improved. Until a few days ago Thunderbird seemed to run without any problems. Any suggestions?

Whenever I’m in a tab where I searched something and I click the three dots the app crashes and closes making it impossible to save bookmarks and etc when having a tab open. But when I’m on the home page it works fine. This is only a problem on my iPad since I first installed the app. My iPad is on the newest iOS update and so is Firefox, also have the latest iPad.
