New feature blablabla... Hey, Mozilla - how about fixing the multiyear old bug, which has like several dozen tickets in bugzilla alone, about randomly losing all open tabs? What good are profiles to me, if one of most important of the secondary features of a browser is fundamentally broken and unreliable? I'm so pissed at Mozilla for their attitude (nothing new really, after the Ugly Bar update and those comments on reddit). If there was a real third browser on Windows I would have jumped ship, despite running FF since beta, both on PC and mobile. Just last month FF managed to kill all my open tabs a third time this year, and that's after no error, completely normal PC shutdown and boot next day. (ps: I know about scrounger)
