I've got Firefox on a widows 10 box for work and ever since whichever ESR update made it just difficult enough to tell which tab is active to be annoying, Firefox crashes for me all the time and it never just takes out a single tab either. I really blame myself though. It only happens after I've had the browser open for weeks, with at least 3 windows open at once, and literally hundreds of open tabs with hundreds more come and gone since Firefox was restarted. I have about:memory bookmarked, and hitting everything in the Free Memory box seems to delay the inevitable a bit while allowing Javascript seems to make it worse. I doubt many others have the problem and I'm impressed Firefox holds up as well as it does!
