A great description of the personally-identifiable information stored in your web browser, relating to Firefox and Mozilla. That's a lot of stuff to sync up. Also good for backup, another good application for my previous sync-yourself idea. How about you have backup/restore information stored remotely with your most critical files? Another good application with FTP Sync. Now how about versioning too....
I just thought of another idea here, how about using your internet habits as a reflection of your personality? Based on what you look at on the internet, this is the personality profile that you fit into. Sort of like SQL Profiler & Query Optimizer for real life. Geeky but probably useful.
I wonder why they have Portugese as a second option there? Any ideas? Is Mozilla the browser of Brazil?
