I frequently have that many tabs open because I use them as lighter one-shot bookmarks (although see onetab). Basically things that I need/want to refer back to once or twice but don't want to bookmark. So they tend to stack up until I go through them and close out the stuff I'm no longer interested in. Really I think FF/etc should probably just garbage collect most of them if they haven't been active for a few days.
