Firefox Community Forum

A few days ago, trying to free up some memory and improve my computer's performance, I deleted the cache and tracking cookies from Firefox (using AVG TuneUp). Since then, I can only load a certain, variable number of tabs and/or pages without every new or reactivated tab or page claiming to have crashed (although about:crashes says that no reports have been submitted). Restoring those pages seems impossible without restarting Firefox or the whole computer. The problem persists in Troubleshoot mode, but as far as I can tell doesn't affect Chrome, although that used even more RAM. I've tried culling open tabs (of which I still probably have far too many, but it's never been an issue before), using the OneTab extension to reduce them to lists of URLs, disabling and re-enabling hardware acceleration, updating Firefox, checking for file corruption and RAM errors and even uninstalling and reinstalling the program, but nothing's worked so far. What might be going on, and what else can I try?

Hi,

I built a new PC a few months ago.

On this PC, Youtube tabs occasionally crash - the problem is intermittent, but common enough to be annoying. I never saw this on my old PC.

As far as I can tell, most of the software is the same as my old PC. Hardware is different if that matters (went from an Intel processor to an AMD, otherwise the component manufacturers are mostly consistent).

Still using Firefox on Windows 11. It's almost always up-to-date and is often up-to-date when the issue occurs. My only add-ons are Reddit Enhancement Suite and uBlock Origin, both of which I used on the old PC.

When I first built it, I did have an issue where I used RAM that was incompatible with my motherboard - that has been resolved and tabs are still crashing. I had found some indication that it could be related to faulty or incompatible hardware, but everything else is working now since fixing the RAM incompatibility.

Sometimes the tab crashes with an error message, sometimes it will simply freeze and I have to entirely close out the tab and re-navigate to the URL of the video I was just watching. The whole browser does not crash - I checked about:crashes and did not see any info that I can confirm coincides with a Youtube tab crash.

I have only seen this issue with Youtube, no other websites.

Thanks for any help that can be provided.

Ok for some reason any of my browsers tabs are crashing I just do whatever it is whether i search or watch movie and after some time 'Gah! your tab crashed' and it's pretty annoying, my discord happens to restart it self and I've exhausted literally anything from re-installing, deleting caches folders absolutely anything.

I've uploaded my latest 2 crashes and hopefully someone can read it and let m know about anything, Thanks in advance!

As of today, when I launch firefox, all of my tabs (which have been working fine for the last several days) crash.

By disabling all of my addons, I get this to go away - and by testing addons one at a time I am able to determine that: -Ublock Origin -Kaskpersky Password Manager Cause all of my tabs to crash.

Whereas: -Sponsorblock for Youtube -Youtube Nonstop Both crash if I visit youtube, but don't affect the browser otherwise.

So it seems like ALL addons are currently broken when they try to affect a tab?
