Thunderbird pushed out an automatic update last night (July 13 2025) to version 140.0.1esr. Since then I cannot complete creating and typing a new message without Thunderbird freezing completely during entry of the text of a new message. I am running Windows-11 home, version 24h2. I have rebooted, etc. multiple times. I also ran thunderbird in troubleshooting mode and the problem still exists.

Please help - as of today Thunderbird is completely useless to me.

As soon as I open Thunderbird, the program freezes before I can click on anything. The password prompt box appears, but regardless of whether I click “Cancel” or try to enter the password, the program freezes and only displays “No response.” I am unable to click on any menu item, as the program freezes even then. I wanted to repair it via Windows, but only the “Uninstall” tab appears in the Control Panel, not “Repair”... It doesn't matter whether I start Thunderbird in safe mode or normal mode. The problem is the same. Version: Thunderbird x64 de 140.0.1 Does anyone have any idea how I can access my emails, which I urgently need? Many thanks! Ekki

It appears that I have a zombie Firefox browser running because when I close the browser using the top right 'X' button, the Firefox processes are still running when I check Task Manager.

If I end the Firefox task and reopen Firefox the first attempt seems to be stuck crashing because there's no crash log, but I can see in the task manager there's a crashhelper. A second attempt opens just fine, but the issue with that is my previously opened browsers are gone even with the setting to reopen them is enabled.

I've tried reinstalling, disabling my extensions, and updating Java, but none of these resolve the issue.

I believe this problem is caused by a false crash recovery loop, every time I open firefox it'll close again and then give me an annoying red striped address bar. I'm sure its not my extensions because I only have Ublock Origin installed.

I can't open the Inbox menu. Any other menu works fine; it's just the inbox menu that doesn't work. If I click on it twice, it crashes and stops working. However, email notifications still pop up properly, and the number increases too.

Firefox keeps crashing my computer while playing graphics-intensive games, yet with Firefox off they function perfectly. This seems to be still an issue since 2015. It'll be a shame to switch browsers since i been using this since it was called Netscape 2

Firefox has been crashing several times an hour for multiple days. I have tried:

I wasn't sure what to select for the type of question so you can move it if you think another type would be better. I would have selected crashes but that isn't an option.

It happened again a few minutes ago while watching Star Trek First Contact. The Phoenix was about to go to warp and Firefox CTD with no crash reporter and when I looked in about:crashes there was no crash report. This exact situation happened twice while watching the movie Signal unknown or whatever the title is.

As the title states, every time I try to zoom into a page using pinch and zoom with my touch-pad, firefox nightly crashes. However, if I try to zoom in using CTRL+ and CTRL-, it works just fine.

I have tried to disable hardware acceleration but it didnt help.

Any help or direction would be appreciated, Thanks!

Ran into an interesting bug with Firefox since installing the macOS26 Dev beta. Whenever I use command space to bring up spotlight, Firefox become unresponsive, the beach ball will spin. It will only happen if Firefox is in focus when I use spotlight, and only if I am signed into Firefox sync.

I am not sure of a way to help replicate this issue as it seems to only happen when signed with Sync, but I would be happy to provide additional if I can.

Why is Firefox crashing so often? What changed? Is there something I need to do to prevent his? Once or twice a week or sometimes a day, but It seems to crash when I am just in my Gmail, sometimes 4 or 5 times an hour. Is Chrome a better option?

The problem began when I was browsing Google maps through Firefox, it gave the prompt to view it through the Google maps app instead. Google maps needed an update, I was on low data mode, I got impatient and canceled that update, then somehow Firefox wasn't allowing me to finish a sentence in the search bar afterwards. Now it doesn't let me open new tabs, exit out of already open tabs, or access the browser settings without freezing for 3 seconds and going to the home screen.

I've updated Firefox to version 139.2, I've searched for some crash log information for iPhone 11 and didn't understand it too well (one suggested to search from Privacy and Security->Analytics and Improvements->Analytics data and to search for "client" but got nothing). I couldn't figure out what more to do with the app from my home screen or settings, I turned my phone off and on yesterday yet it still happened. Any advice would be appreciated, I'm not experienced with technical things and don't want to risk having my bookmarks or passwords be erased in any way.

IOS version is 18.4.1 if that helps.

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.

OK let me start with this - I never thought that I would say this but I am truly beginning to truly HATE - I MEAN HATE FIREFOX AND MOZILLA. Here's why. For the past several months (4-6 months) I have been using a website and it crashes. The window that comes up after the crash states two things. #1, a crash log or report has been saved and sent. #2, Click here to re-establish connection to website. Now this has been going on as I have stated that this has been happening every time I use the website. NO ONE from Mozilla or Firefox has ever acknowledged receiving or trying to fix the crash log that is supposedly in your hands after the crash is reported. This has become really annoying. NOW, I have sent numerous email to Mozilla and Firefox asking for the help to solve this issue and what do I get ZIP, NADA, ZILCH as in NOTHING! Why is that - no one has time to deal with the crash logs that are supposedly being sent every time I get a crash?

Just a day or so ago I got an email from a Mozilla guy Wai Tse who said that he wouldn't do anything because he worked for Mozilla and not Firefox. He sent me a link that I opened and when I did it had MOZILLA AND FIREFOX everywhere. So now I am thinking WTF people - is this a personal thing? Am I not donating enough money to your calls for help and monthly to get a response to this issue that you are suppose to be getting information on everytime it crashes. I am giving up and trying to be nice and or patient with you since I have been ignored for months and months.

I'm sitting here thinking that once again I am just jerking off, no one cares no one is going to respond except for Wai Tse who can't take the time from his busy day and go one step beyond his or her job description and HELP.

Firefox indicated a new version was available and I installed it. After restarting the app, links will not connect and I receive this message.: Gah. Your tab just crashed. We can help!

Choose Restore This Tab or Restore All Crashed Tabs to reload the page/pages.

But nothing helps. I cannot reach most of the sites where I need to work.

I have installed Firefox but when trying to load it up, the programme crashes showing three crash report windows. Any idea how to fix?
