My tabs crash all the time. Sometimes it'll go a while without crashing, other times it's literally every two seconds. Particularly if I'm doing anything that doesn't autosave. Thanks. Sometimes it's just whatever tab I'm on (or occasionally I'll click on one I've had open in the background only to discover it crashed at some point, other times (and not infrequently!) it crashes the entire browser. Sometimes when it does that, it also logs me out of everything for no particular reason as a little sadistic cherry on top. The passwords are still saved I'm just logged out of EVERYTHING. A few times, it seemed to have made my bookmarks go away, but force-stopping it and re-entering made them reappear, so they weren't deleted. I don't know what's going on but I'm at my wit's end. The crash reports mostly just say EXCEPTION_ACCESS_VIOLATION_WRITE (I haven't checked every single one individually since there's too many, but the ones I've clicked on all say that as far as I recall). If this keeps up I'm going to have to switch browsers or something because I'm actually losing it.

I have Firefox on two separate computers, a desktop running Win7Prof64bit and a laptop running Win10Pro 64bit. Both Firefox installations crash constantly, ie every 10 - 15 mins. They show the "Gah! Firefox just crashed. Please tell us what you were doing", and the box to return the data to Mozilla. With Restore This Tab at the bottom.

I always send you these reports but in about a year, the problem remains the same. Nothing has improved, I never hear back from you. Two different PCs, two different OSs, constant reports, no improvement. Why do I never hear from you? Why does this problem continue endlessly? I'm wasting my time sending you the reports. You take no notice. If you do, why does the problem continue and why do I never hear from you?

We are experiencing an ongoing issue with Firefox that persists even after performing the following troubleshooting steps: - Uninstalled Firefox completely. - Removed all browser add-ons and extensions. - Reinstalled the latest version of Firefox. Despite these steps, the issue still occurs: Browser crashes, pages not loading, extension not working. Additional Information: - Operating System: Windows 11 Pro - Firefox Version: 145.0.1 - Error Message:

We would appreciate guidance on resolving this problem, as standard troubleshooting has not resolved it.

Thank you in advance for your assistance. Kind regards, Edward

In past 2 days I've experienced Firefox randomly closing all open firefox windows and then bringing them back after a brief delay. There is no mention of an update or other reason while this would occur.

Since the latest Firefox update, it has frozen the app & crashed my computer multiple times within a few days; it has also caused problems logging into my primary bank account ("access denied") but has nothing to do with the bank (I called the bank; no problems there, but they suggest using Chrome browser. NO WAY!) Every time Firefox has updated the past few months, it has interfered with my password vault’s proper functioning {Last Pass}. I am using a late 2012 Mac mini, running OS 10.15.1 (the newest acceptable OS for my computer). I attribute some of the problem to their adding a number of new features without making certain the basic app is stable.

I am running Firefox 151.0.4 on a Win 11 (25H2) AMD Ryzen 5, 32 GB ram. Every time I close Firefox, it generates a crash report. That takes several minutes during which I can't start a new Firefox window. The crash report says the report was submitted successfully but when I look in about:crashes the reports shows they need to be submitted.

I ran in troubleshoot mode and disabled all plugins and did not see any extensions listed. I restarted and it still crashes. Firefox seems to run fine. But the crashes when it closes are annoying and disruptive.

I get random crashes while streaming video (for example youtube). I am using a laptop with 2 GPUs (integrated AMD and dedicated Nvidia) and a secondary monitor. If the Firefox windows is on the laptop display I never get crashes but on the secondary display I get around 1-2/hour. Also, this only happens with hardware acceleration enabled in Firefox settings, if I deactivate it then the issue is gone. I think it runs on the AMD integrated graphics, based on what I see in task manager. I also have uBlock origin, haven't tried deactivating it yet. The crashses consist in a black screen from which I can only recorver by doing a hard reset.

Any suggestions on what to try?

1. Whenever I open Firefox for the first time since boot, it crashes, and I have to click on it a second time for a window to actually show up. Once it shows up, it's forgotten all about the previous session - none of my tabs re-open, the window opens up maximized.

2. Whenever I close the last open window, my previous tabs are completely forgotten. Checking task manager reveals that there are 10 or 11 Firefox processes that are still running.

• I have a second Windows 11 device that DOESN'T exhibit any of these issues and works correctly. Closing Firefox does not leave any running processes around.
• "Open previous windows and tabs" is enabled in options.
• "Firefox will: Remember history" is set in the History options.
• Both devices are running Firefox 137.0.2 64 bit.

So for three days now, my firefox constantly crashes. I would be reading a story online or watching a video on Youtube and then it will suddenly freeze. In videos, it'll still play the sound but the screen will freeze. I can't pause or stop it. Then either Firefox crashes and closes or I have to close it for it to stop. Sometimes, when I try opening it again, it still won't open. I used to have 50 tabs open and never ad this issue. After this, I closed all the open tabs, even deactivated a bunch of extensions, run malware detection, and still the issue continues. I don't know what the problem is. I even followed instructions and deactivated hardware acceleration options in Performance. And I have all AI options turned off too. The app also recently was updated.

Mozilla Firefox constantly not responding. I have been unable to access any of my sites, as the browser doesn't seem to be working. Very frustrating. How can I refresh Firefox to reset it??

I did a "dnf update" on my system yesterday which upgraded firefox from 137 to 138, however I don't think that is the issue because I downgraded back to 137 and removed the ~/.mozilla directory to create a new profile and I have the same issue. So this might be an issue with Fedora. When I started with a new profile after removing ~/.mozilla using either v137 or v138 when I get to the create a master password in settings firefox freezes and I have to kill it. Before downgrading and creating a new profile I first noticed the issue when I went to a site with a saved login and when I clicked on the password box to bring up the saved password firefox froze. Just accessing the password menu will cause it to freeze. Any help/pointers would be appreciated.

This version is crashing its tabs and the program and often the entire windows system. It is the worst version ever made. Did you even beta test it? When will it be fixed?

Hello, after the most recent Firefox update, and it doesn't happen with every web page but it seems to be most frequent on ones I have never visited, that I get a tab that says "Gah! Your tab just crashed". If I close the browser and reopen it, then reload the crashed tab from my recent History, it seems to work. Anyone else experiencing this (Win 10 Pro 64x desktop PC)?
