i don't believe its memory issues because my PC has 61.6 GB of 474 GB free, and i never got these crashes before the update, with the same amount of data. dunno what else to add here, let me know if i need to provide something more

I downgraded to Firefox 140ESR yesterday to get rid of the silly circles and gradients. The update was so visually distracting I found the browser to be unusable. However, now almost any website I visit gives me a Gah your tab just crashed. Is there a way to fix this while staying on 140ESR? Please refrain from answering if your solution is to upgrade. Thanks.

There is nothing obviously happening with my browser. It doesn't crash when I am using it. But I keep getting, several times/day, the dialog box shown in added images below.

So, similar to this post but I haven't downgraded, only upgraded.

OS: Windows 11 (26100.8893) Browser: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:153.0) Gecko/20100101 Firefox/153.0

I can load it up in the morning, load all my standard tabs, then not too long into it a tab will 'crash' and require a reload. The reload then says its a dramatic crash and the whole browser needs to restart. Soft or Hard (i.e. "Exit") restarts always then ask to create a new profile on startup. This means I lose so much configuration (settings, etc) that is not in the Account Sync, meaning huge amounts of time have been wasted setting Firefox back up again every day.

When I go to about:profiles I can see all the old and new profiles (recently cleaned up all the old ones).

I do use my FF Account across various versions of Firefox (run a linux OS that still has a 14x version - need to upgrade OS to get more recent, but its a significant upgrade that had previously failed so not high on my 'want to resolve' list) - all the Windows OS's have the latest FF.

The Firefox window closes after uploading a file to a hosting site In fact Firefox is not completely closed. I just need to click the Firefox icon in the taskbar to open the window again. it's not a big deal but it's still annoying.

Firefox has recently started turning itself off. There is a failure message and it self-reports the issue. However it will do this without any website loaded, it just fails to continue running without a website being loaded. This happens everyday. The application will not continue to run just by being an open application with an empty about:newtab This is very frustrating.

I mostly watch YouTube channels on Firefox on my laptop, but recently have had to change over to Microsoft Edge browser to watch YouTube. The reason is that during a channel stream, when an ad wants to play, YouTube and Firefox freeze and the only way to exit the screen is to either attempt to close YouTube or even open Task Manager to shut down all instances of the Firefox software. Firefox is by far my preferred browser and I'm frustrated that it is unusable in its current state. I tried to uninstall and reinstall, but this did not work. Thank you in advance for your help.

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!

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!
