Google Reader jammed on me in offline mode today. Try as I might, it wouldn't switch back to online mode even after I let it run for an hour apparently "synchronizing". Restarting the browser and clearing caches didn't help.
After a couple of Google searches I did not find any information regarding how to manually clear out Google Gears offline storage. So here's one way... (probably not the best way)
- First close your browser.
- You'll find the Google Gears offline data store for Firefox inside your Firefox profile directory. On my machine, that folder is "C:\Documents and Settings\Jeff\Local Settings\Application Data\Mozilla\Firefox\Profiles\wb2qohxr.default\Google Gears for Firefox".
- The offline data store contains a couple bookkeeping files ("localserver.db" and "permissions.db") and individual directories for each domain name with offline storage. Just delete the appropriate directory. In my case it was "www.google.com".
- Restart your browser and away you go...
Works fine now.
