Firefox unusable, excess memory usage, hang ups, crashes.
Greetings, Windows 10, latest version, recent uninstall then re-install. When I load Firefox and populate several tabs, Windows Task Manager shows that the "Mem" column (2nd in "Processes" tab) slowly lists increasing memory, up to over 1200 MB, at which point there are hangups, "not responding," and finally seizure or crash. I tried the "about:crashes" route, and will try again if you want. In contrast, I can have over 50 tabs open on Google Chrome and memory usage peaks at less than 200 MB. I'm using Chrome now, but will gladly communicate using Firefox if you want.
