That exact thing happening way too often—with like a half-dozen very normal tabs open, and when FF wasn't even in focus—was what drove me first to Chrome (where I could open a stupid number of heavy tabs and not see problems as bad as FF), then later to Safari (for the double-digit-percentage better battery life than Chrome) on my Macbooks, and that was... wow, probably 2010 or so.
