Roaming browser state
John Ludwig and I were discussing that hassle of installing plugins like Password Composer on every one of the six or so machines that we manage between home and work.
This touches on the general issue of roaming browser state. The browser enables applications that roam from machine to machine, but ironically doesn’t do a good job of roaming its own state.
One day you’ll be able to set up your web browser on one machine and have exactly the same experience on any other machine—the same bookmarks, the same cookies, the same plugins, the same preferences, etc.
A9 is heading in this direction with some of their toolbar extensions, but it creeps me out a little bit to have Amazon hoarding that information about me. I think I trust either Microsoft or Mozilla more.
Would I pay for a universal browser feature? No. Would I choose one browser over another, or one OS over another because it? Very possibly.
