Or Firefox 4 when Firefox 6 is released in August? I'm curious about this too.
Of course, "not supported" isn't the same as "not working". For Firefox (just like Chrome), I doubt there will be changes breaking enough to cause a problem. The real question is if they'll start using features (e.g. canvas or newer selectors) not available in those earlier browsers for major functionality in their apps.
