An actual release time has now been announced, 10am PDT (California time). So that means that here in New Zealand will be 5am the 18th of June (tomorrow). When you wake up, you’ll find Firefox 3 all ready to download for your enjoyment

Extensions have already been busy updating, All-in-one sidebar, Greasemonkey, Firebug, etc etc. Firefox 3 will let you know which extensions are broken when it first starts so there shouldn’t be any troubles.
