Firefox Community Forum

Mozilla Firefox began to crash all the time; crashes happen almost every ten minutes, and it happens with every site. It still lasts about for several weeks. I tried to reinstall Firefox; I updated my drivers for my computer; I cleared cash and history in the settings; I tried to delete some files from Firefox's folder. All these things did not help. The crashes may happen with any site, and it can happen any time. I have no problem with memory shortage. My system consists of Ryzen 7 5800x, Radeon RX 7800 XT and G.Skill Flare X (for AMD) DDR4 2x16Gb.

Since a few weeks I have been encountering an issue where tabs in Firefox would frequently crash. I do have various add-ons installed, however I haven't installed any new ones around the time the issue has been occurring. I've been unable to track down which add-on or if any add-on might be causing this.

Trying to search for this issue all I could come up with is that it might be an issue of a faulty CPU. I have an i9-13900KF which has been known to be part of the Intel generation with serious flaws. However I already installed a BIOS update and applied Intel's recommended settings to undervolt the CPU to prevent any issues. This was well before the Firefox tab crashing issue happened. So I'm not sure if it can really be the issue of a faulty CPU, but I've also had issues of other programs randomly crashing recently (like Discord or Steam).

The tab crash can occur on any website, for example Youtube, Duckduckgo, Protonmail, etc. The crash reason always is either "EXCEPTION_ACCESS_VIOLATION_READ" or just "EXCEPTION_ACCESS_VIOLATION". The crash also most of the time (but not always) occurs when loading the page itself or a video / live stream on it. But not when browsing an already loaded page (for example this forum post page I'm writing right now).

Here are some of the crash reports I've submitted:

EXCEPTION_ACCESS_VIOLATION_READ: https://crash-stats.mozilla.org/report/index/60309ae8-8cad-43ac-8b9b-172b10250815 https://crash-stats.mozilla.org/report/index/fecef0ab-d874-4cb5-990b-e49650250815

Rather rare "EXCEPTION_ACCESS_VIOLATION": https://crash-stats.mozilla.org/report/index/114b26fa-4e10-442c-bbd5-406630250812

Could someone help me narrow down this issue? Can it really be a faulty CPU and I need to trade mine in?

I've done all the troubleshooting I could find, including: Uninstalling, tried using beta ff, disabled hardware acceleration, disabled/removed all extensions, memtest, updated various drivers. Still frequent tab crashes Tried two other browsers and neither of those had any issues. No crashing on edge or duckduck.

Crash reason seem to be mostly EXCEPTION_ACCESS_VIOLATION_READ and EXCEPTION_BREAKPOINT
