Firefox: форум сообщества

On Thursday 3rd September 2026 Firefox stopped working. I tried lots of things to get it to work to no avail. Today, 8th September 2026, I had already deleted the Firefox that was already on my PC so I downloaded a fresh copy from the Firefox website and installed it. It ran perfectly for about 30 minutes then I shut it down. 5 Minutes later, a Firefox crash report appeared which I duly sent of. Checking Event Manager a string of error messages saying the same thing, Its the XUL.DLL file that keep crashing! This was the same file that caused the failure last week. I had made sure that XUL.DLL was not on the pc when I downloaded Firefox today. When I click on the Firefox icon it open but stays on a black lower half of the screen and boxes at the top, white lined but black and transparent lines moving left to right across them, eventually it fails and closes, after a few minutes it send the crash report. Its a shame because I have used Firefox for many, many years and now having to use Edge!!!!

Running Windows 10 (have extended security updates). Starting at version 153.0 Firefox hangs (spinning cursor) until Windows realizes it is not responding and lets me stop the program. Seems to be independent of the website (even happened on a Mozilla page). Have tried a couple of 153.xx updates and also 154 but behaves the same. On a Dell Inspiron 7570:

Hi, Firstly, thank you for all your services.

When working in a tab, Whatsapp, Youtube, or even Buzilla when I want to report this, the tab just crash's. Sometimes I can restore it immediately, but other times if I click on "Restore this tab" repeatedly, the whole window crash's!

Hello, we have a DLL product that is injected into Firefox, and it generally works properly. However, from time to time, we encounter crashes like this in individual tabs.

Could you please help us understand what might be causing these crashes?

I’m also sharing the crash report for reference.

Hi There,

I'm a Professional Web Designer, and I need to make a lot of meeting through Google Meet. I was using Chrome previously. When I try to use my Web Cam, Firefox completely crush my web cam. Means, no other apps can't use the web cam including Meet until I pull the flag out of my PC's USB port.

The only fix is to disable hardware acceleration. But I need that as well. So chating Gemini, I figured out that changing this rule media.windows-media-foundation.allow-d3d11-dxva to false on about:config fixes the issue with having Hardware Acceleration enabled.

It turns out that, according to some reddit uses, Firefox uses API from medieval age for handling DirectX3d.

I love Firefox, and I want it to grow nowadays more than ever by looking at the browser market and what they are doing with Ad Blockers. Please take a look at Firefox's performance for the good.

My System: OS: Windows 11 Pro CPU: Intel Core Ultra 7 270k Plus GPU: NVIDIA 5070 TI 16GB No shortage of SSD and Ram. Plenty of them available.

Can Firefox work on that issue, so I don't have to go to workaround like this? I love Firefox and I want it to compete with chromium for good. But having issues like this left us no option but to choose alternative.

Thank you!

I used firefox troubleshoot mode to see if the problem is caused by an extension etc. But my tabs were still crashing, this time, firefox as a whole crashed. Sometimes a tab crashes, and sometimes firefox crashes. I tried to troubleshoot with an llm, it said that i don´t have enough RAM, i have 8Gb, but its shared between RAM and VRAM. I was on fedora before, the problem occurred there so i switched to mint with the thought that mint is more lightweight so it should have more RAM available for tabs. But that wasn´t the case. Sometimes i only have 1 tab open, nothing else on firefox and on my laptop open at that time, but the tab still crashes.

I hope i´ve provided enough information, if not, let me know what your missing to fix and i hope i can provide it :)

Why is Firefox always crashing on Windows-XI, especially from third-party servers and whenever scrolling? This has been happening for the last nine months (ver.146>Beta), at least. Does my SSD need replaced and/or my Win-XI reinstalled? Either way, this is happening on every Firefox browser that I have, including Windows-XPIII> and Android-16>. This is where my team always swore that Java6>, .Net3>, Python3>, and even Swift3> love to crash all user-interfaces/shells, and make users lose all random access memory. Is there any suggestion to fix this bug of Firefox, or must I replace the SSD?

Hi everyone,

Firefox on my desktop has been crashing frequently, sometimes shortly after opening it and other times while browsing normally. There doesn't seem to be one specific website or action that consistently causes the crash.

I've already tried restarting Firefox and my computer, but the problem keeps coming back.

Has anyone experienced frequent Firefox desktop crashes recently? I'd appreciate any suggestions on what I should check first, especially regarding extensions, hardware acceleration, crash reports, or corrupted profile data.

I'm happy to provide my Firefox version, Windows version, and crash report details if needed.

Thanks in advance for any help!

Firefox browser opening and closing on it's own, rapidly opening multiple windows at once, over the top of all other open pages on my computer. I've restarted my computer, run a virus scan, cleaned my keyboard (no stuck keys), unplugged all extra things (web cam, mouse), nothing seems to work. I use Chrome and Firefox simultaneously for different things, and have never had an issue before.

Hi, My Firefox crashes when alt tabbing into it from a 3D accelerated fullscreen application. Sometimes I am able to just close Firefox, most of the time the only thing helping is a complete system restart.

Hardware is an AMD Ryzen 5800X with a Radeon 6900xt and 32Gb of Ram. Windows 11 and the graphics drivers are up to date.

Firefox itself does not seem to recognize the crash and does not have any logs of it.
