I prob dont get up to 100 tabs. but I do like to open different browser instances, one for mail, fb, twitter, etc. one with a bunch of news articles (and of course, for evert hn article, the comments) one for whatever prog language im currently in. which is usually thw biggest, that contains multiple how-tos, searches for commands, at least 10 tabs from the 'official' site, and its this one that needs to stay open for days/weeks as im working on a project and constantly refrencing info i previously knew id need. also, each browaer instance is usuaaly in a doff workspace, to keep work and play seperate.
