Hello, Whenever I open Firefox, it crashes repeatedly. This has been going on for at least a couple of weeks, whether it's right when I open it or hours later when I'm in the middle of something. I've disabled extensions, ran it in troubleshoot, and done the steps advised to no avail. Any help would be greatly appreciated as this has rendered Firefox unusable. Attached is a screenshot of the digits of the crash reports, as well as the link for the one from today.

My ram is broken in certain memory locations, writing to these locations brick the program, or if the program is kernel-level, I will blue screen.

I don't want to spend any more on my PC. It was the largest amount of money I had ever seen when I first bought it. Even if I have way more resources now, I don't believe that a few faulty locations in my memory should be causing so many problems for myself and for developers who have no clue why their users keep crashing.

It is either my RAM or VRAM. Disabling XMP on my RAM dampened these issues but couldn't fully solve them.

It's exactly as I said. Normal programs just crash. Kernel-level programs or anti-cheats can entirely blue screen my PC. It all has to do with where these programs are writing to in my hardware. It's only a few locations that I have faulty. Most programs work fine. Most games work fine. Most crashes are very transient.

Firefox is a transient and common crasher for me. It's so painful to be scrolling a page and have the page crash, just for the previous page to load instead of the newer one that I was on, and on top of that I could also be losing work or effort.

I know this isn't exactly a dev support page, but this problem is so recurring that I don't know what to think anymore. There has to be a way to check which memory locations are fried without causing a bluescreen or crashing the program. Maybe it's a Windows issue and devs could easily fix it, if it weren't for Windows bottlenecks like labelling the faulty locations as "protected". I've seen at least 1 crash where the output said something like "Error: tried writing to protected location" blah blah blah then it spit out some hexcode or exact location and blahblahblah. And that was the entire error message.

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.

- However I think it may be to do with a recent bookmark entry stored in the bookmarks bar?? The website is a national UK hardware store and it seems to open OK. I cannot be sure but I think the problem started after I added this bookmark. It is a real nuisance and I have had to switch to Edge. Please advise how I might fix the problem.
