Google has released a new product, Google Browser Sync. It has an excellent premise; it syncs all of your different firefox profiles between your computers, so that you have one central profile, stored with Google, with the extension automatically downloading that profile (cookies, passwords, bookmarks, history. I don’t know if it does extensions and themes.)

I’ve often thought about writing such an extension myself, which I would have done if I could write extensions! I would add an option, though. I would allow syncing across a local network, as this would certainly increase startup times (which apparently is an issue for some people), and removes the potential privacy issue. The other possible problem with the extension is that it copies everything. For example, I would like to be able to set it to copy fewer bookmark folders to my bookmark toolbar folder on my laptop than on my desktop, as the laptop has a significantly smaller screen.
