Just installed Firefox 3 (along with half the planet) and it's really bad. When it opens the bookmarks bar is blank, attempting to bookmark anything fails no matter what technique I use to do it. The URL doesn't appear in the navigation bar and if I type a URL into it directly and hit enter it does nothing. The URL will appear if I click the favicon in the corner but that's not much help really! Also, if I set a homepage in preferences it doesn't work. It opens all new windows full screen and blank and if I click the home button it either does nothing or takes me to the Firefox Google start page. I've deleted old preferences/caches/profiles etc... wiped it entirely from my system, including all installed files as above and then reinstalled from a new DMG, not the first one in case it was corrupt and still nothing. Any ideas?
