Gnome keeps its URL handlers in gconf (desktop>gnome>url-handlers>http); you may run gconf-editor to check it out. The value for [command] should be "x-www-browser %s" so it uses /usr/bin/x-www-browser, which is a symbolic link to /etc/alternatives/x-www-browser (another symlink). "update-alternatives --config" changes only that last symlink in /etc/alternatives/.
Apparently you made it point straight to "firefox-3.5 %s". That's okay, but other applications may call "x-www-browser".
