I just went to gears.google.com using IceWeasel (Debian's Firefox) in qole's Turbo Easy Debian. Strangely, it said my browser was not currently supported -- a bad sign considering they do say they support Gears for Firefox 1.5+ on Linux in general. Even microB gives me a fat "Install Gears" button (not that anything good comes of it...). I'm not eager to try User Agent spoofing. So I appear to be stuck.
