2 years at best , still able to run new games on highest settings.
twice in past 2 weeks. Completely random.
If you were interested extensions are:
Libredirect
Improve youtube (for youtube & videos)
LiveTL
Auto Tab discard (added after finding firefox devouring memory for some reason to the point youtube was lagging)
BetterTTV
Panorama tab groups
600% Sound Volume
Currnetly 52 tabs open, which I did both on Chrome and Opera as well.
Again this is still not to the point that I feel like I can't deal with it. The crashes were completely random and not to the point of becoming a trend.
