Depends, I have several profiles for doing different things. These are the ones that survived so far, so they must be the ones that are important("can't live without" is a strong phrase) - Normal use: Adblock Plus, DownThemAll, Flashblock, Greasemonkey, Session Manager, TreeStyleTabs and User Agent Switcher. - Development: Firebug, Httpfox, User Agent Switcher, Web Developer and YSlow I separate them because of performance reasons and because the dev profile needs to be cleared frequently and so on..
