Since you're a chrome user, I'm not sure that you've heard of this, but firefox sync is amazing! Syncs history/bookmarks/tabs/settings/passwords across all your firefox instances, including firefox for android. I can read something on my phone, while on the bus, then get home and open the same tab on my computer or vice-versa. Or if setting up a new machine, I can add it to my sync profile, and it near instantly has all of my browsing history etc.

I feel that's much more useful than syncing extensions, as those can be machine dependant (i.e. i wouldn't want the same layout modifications with firefox on my tiny netbook screen that i do on my desktop)
