After reading this, I am inspired to point out my favorite fire fox trick: In firefox, you can assign keywords to bookmarks. So, for example, I have a bookmark for gmail, I assign the keyword "m". In the address bar, I type "m" and get gmail. "r" = google reader, "s" = safari books online, etc.

I only have about 10 bookmarks in the browser, and in fact, the only reason I have those is because of this shortcut feature. For all other bookmarks I just use del.icio.us.
