I have a Dell XPS with dual GPU - integrated and dedicated. I've been having Firefox tabs crashing ever since updating my Intel drivers. The newest driver update fixes some sluggishness I was having, but now Firefox is crashing. Things I've done: Reinstalled a fresh copy of Firefox Disabled Hardware Acceleration Reinstalled the iGPU driver Downgraded Firefox 1 version Chkdsk'd about:crashes hints towards dual gpu issue from what I can understand
