Firefox updatated recently, 37.0.1, i now get random crashes and 90% of the time the browser will crash on close. So i refreshed firefox and started enabling addons, when i enabled 360 toolbar 2014.7.12.7 and restarted firefox, the problem started again, i disabled norton toolbar and firefox is fine. I also notice sometimes typing becomes slow when the toolbar is enabled almost like some memory leak. PC INFO: Win 8.1 64bit, i7 4770k @ 4.23ghz, 32 gig of ram, Gtx Titans 2 way SLI.
Cheers
