How to delete Google Gears offline data

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.
