Kicks and Kisses

I use two different computers. Both have Mozilla Firefox. I spend significant time over internet. When I am in office I make some bookmarks as I do at home. My search engine settings also differ based on requirements. Both might have different add on, preferences, settings. I always try to make settings same for both. This helps increasing my efficiency. Do I always need to customize browser to get seamless user experience

I was just thinking of sync mechanism of multiple browser settings. Can Mozilla assign me a log in / password. Once I log in to browser it stores all my setting including bookmarks, add on, search engine settings, and search history, browsing history, browser version at one central location. Once I log in to another PC and enter my user name password. It makes the browser exactly I have. I can do this sync once in a while based on need.

I will feel as always I am working on same browser. If I update something it should automatic update in all other browser once I log in, if I log in to that browser. Once I sign out the browser, it brings back to its normal settings.

The idea can be extended to thick client applications with a server in between. This server keeps track of settings, versions, additions, customization to a thick client application on particular machine. Consider IM Client.

Can this idea make both the browser function seamless?
