Some people (like me) have stopped using bookmarks and simply leave open interesting pages. I have ~20 browser windows open, each window is a virtual workplace. One is political news, one is tech news (featuring hacker news, the Register, slashdot, appleinsider...) one is Java SE API tabs, one is Clojure, one is imageboards. While 500 tabs is a bit much, I can easily get to 200 without getting lost. It is simply a way to organize my stuff. Had one window with several tabs open for Scala, then found that Scala is not for me. Closed that window and it is all gone. No need to fiddle with bookmarks. That said, the missing 64bit support will surely not make me leave Firefox. After all, it will surely come back over time.
