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.

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.

While playing Free Games.org and Free Mahjong also on AOL Mail Firefox crashes after a few moments. I performed security scans and restarted, still crashing.

Firefox keeps crashing I've followed all steps, still crashing - memory / disk/ system/restart/troubleshooting I did have animaze installed but removed and still crashing

Above is latest crash report

Firefox just updated to 152 this evening on my Windows 11 Pro system. It seems slow compared to prior versions. Also , every time you log out , it crashes and activates crashreporter which files the report. Any clues? Nothing changed on the system except for Firefox.

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.

here are the first few lines of a recent crash report: Firefox 147.0.1 Crash Report [@ shutdownhang | mozilla::SpinEventLoopUntil | nsThreadPool::ShutdownWithTimeout ]

I usually use firefox to download things, and watch videos, however, sometimes, when I change tabs, try to minimise firefox, close a pop up, even if I just pause a video, it randomly decides to instead completely freeze and require the app to be completely restarted, and it occasionally decides to roll back my search history.

In fact, Firefox crashed as I was writing this, i'm lucky my progress was saved, these issues have made firefox completely unusable about 70%-80% of the time, and i'm running out of browsers to switch to, opera is run on lies, chrome is just bad, and now firefox is dying.

Just for reference, no other application or web browser that has ever been on my current device has ever acted like this, I'm currently using a decent PC running Windows 10

My browser started crashing after the latest update, and it still crashes even in Safe Mode. It doesn’t close immediately upon opening; instead, it shuts down suddenly after about one minute or longer. This issue never occurred before and only started appearing after the recent update. My system is Windows 11, with the following detailed information: Edition: Windows 11 Pro Version: 23H2 Install date: September 17, 2023 OS build: 22631.5624 Experience: Windows Feature Experience Pack 1000.22700.1106.0

Since the 152.0 update I've experienced near nonstop browser crashing, it crashed twice as I was trying to type up and submit this message,

Is this a known issue or solely on my end? running 64 bit, windows 10

Following my traumatic brain injury I do have a reading disability search that perusing your articles could take me up to a week.

As you see I am running Windows 10 on a laptop which Microsoft said I was good for another year using this OS. Your latest download executed and after 2 reboots continuously crashes after trying to view any of the five windows a browser I had open with multiple tabs in each.

You updated your browser on my pc today. Now I can’t open it. It opens but has not opened any sites. I’ve had to use bing. I’ve used your browser for several years but unfortunately I’ve not been able to. It locks up when I try to open YouTube. The blue circle starts and locks up. Too bad.

for years now I have had this issue when browsing. It is so annoying. I have tried all the suggested troubleshooting. I deleted all extensions. This helped for a while, but not for long. Now it's so tedious to browse that I am thinking of getting rid of Firefox. It has just become unusable and no one can seem to fix it. I am using Windows 10 and no extensions. It often happens when I first open a page and while the page is being pulled up.

I cannot use Firefox without it blowing up my memory to 86GB used in Activity Monitor. I've cleared my cache, closed all my tabs and bookmarked them. I have a Macbook Air M1 2020. I've tried restarting and am definitely using the current version of Firefox. I also updated to the latest OS Tahoe 26.5 to see if that helped. What should I do next please?!
