Hello,

Ever since latest update (153.0 (64 bits) everything crash. I can open Firefox, but as soon as I enter a website, regardless of what it is, it won't load.

If i try to close the app, there's always a process that keeps running. It can't close. And if I try to force it it says that access is refused.

After that I keep receiving these errors that Firefox is already open and I need to close the last process of Firefox to continue but even if I say to close, it keeps repeating until my PC finally crash.

Everything was working 100% until Firefox updated itself. No Windows update nothing.

I can't even send crash report since it does the same error.

Firefox not responding. I have tried everything on the Help pages. I have tried reset of everything. I have uninstalled and reinstalled from scratch. Still: when I open it: Firefox does not respond. And everything else also is very slow then. In Windows joblist I can see Firefox with 7-15 threads. One of them "not responding". I have no problems with Chrome nor Edge - W11, 16GB Ram

Hello, I've been watching MSNOW at 4pm eastern and after about half an hour it crashes. I get a message to send a report and restore the tab. I restore the tab which works for maybe ten minutes and crashes again. I am using Windows 11 on a new computer. I'd appreciate some assistance. Thanks. Bruce Caress

Moderator note: This question has been edited to precise Firefox and OS version, based on the crash reports.

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?

Firefox is CONSTANTLY crashing now and I'm about ready to switch to another browser unless someone can give me a reason to stay.

I've been using Firefox all morning. Now, for some unknown reason, every time I start it up, it immediately crashes Windows. I mean, within 1 second or so. There's no time to do anything. After the fourth crash in a row, I just restarted Windows again. It was humming along happily for 10 minutes or so, and then crashed as soon as I started Firefox. After the first crash, the first thing it did was update, but that didn't fix anything. I'd love to share data with you but I'm forced to use Edge right now.

Tabs will crash over and over again. I can barely look at any given page for longer than a minute or two. What happened?? Firefox was never like this before. It just crashed in the middle of me typing this LMAO. Using Brave in the meantime. This is ridiculous.

Since the latest Firefox latest update yesterday (02/24/2026), each time I try to open a new tab in Firefox it crashes. I get a "gah, your tab has crashed" message but when I hit the "restore" link nothing happens. How do I fix this at my end? Thank you.

Hi, I have a problem of the upto date version of firefox (X64) constantly crashing on Windows 11, 64 bit some time it only stays up & running for just a matter of minutes before closing without warning I can't work out what is causing it, I don't know if it saves a loading log file, updated several times but no noticeable change, still doing it at random.

Firefox keeps suddenly crashing, I have reset Firefox, deleted it and reinstalled it, I have used DISM and SFC to repair any issues and I have set up a new profile within Firefox with no extensions, but still I have the same issue, either tabs suddenly crash or the whole Firefox does.

I wanted to report that Firefox froze or crashed. I could not close it and had to Endtask it. I am running the latest version supposedly on Windows 11. Why did this occur?

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.

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000000a (0x0000000000000030, 0x0000000000000002, 0x0000000000000000, 0xfffff80274225392) CAUSE WAS FIREFOX.EXE
