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. Currently using a nightly build, tried ff safe mode, tried pc safe mode, still crashing.
