This morning I had a very annoying problem with my Gmail account; it looks like Google have been tweaking since the release of Buzz. All my inbox folders and labels had disappeared. Viewing from Firefox everything was fine, but in Google Chrome nothing…. arghh!
After a bit if thinking, the only difference between the two setups (apart from the browser of course) was the fact that in Chrome I’m using Offline mode (Google Gears). After quickly disabling this and re-enabling, everything worked perfectly again. I will keep that in mind for future issues.
Note: When re-enabling Offline mode Gears will have to sync with the mail server again which could take a while.
