When ever i press "Show History" i get a black screen instead of showing me what it suposed to. When the black screen appears the computer reacts like its on full throtle especially the videocard. I tried to completly uninstall mozilla(including deltetion of the all the files from pc) but the problem stil persists. All drivers up to date. Tried the forums but i couldnt find the right solution. I honestly dont know how to solve this problem since i never had it on my old computer on all my years since i use firefox, but since i have the new computer it started to happen.
