Is it possible to use Google Gears inside of another Firefox extension?
Basically, i want to implement Offline/Online XUL application with ability to upload data to server.

SQLite character encoding for Google Gears
We're using jQuery to get a JSON-string from our server (UTF-8 response, also UTF-8 request through jQuery) and put this JSON into a Google Gears WorkerPool.

Google Gears hangs when capturing (unmanaged resource store)
Our code was written based on the example from Google Gears' own docs. We're using an unmanaged resource store. So we declare the files in an array, create the store, and capture all the files. Trouble is, the capturing process hangs. It always hangs on a random file (no discernible pattern has emerged), and when you reload the page, it...

Does anyone have any ideas about how I might go about "injecting" code in such a scenario? The only method I can think of is using a webservice an...
