Not running it in Ubuntu, but used to run it on Arch. Or should be given a new executable, firefox-aurora. As for add-ons, most developers seem to mark comparability for future versions, so you shouldn't have to worry too much. You can always edit them to say they're compatible with the version of Firefox you're running and see if they have issues.
