Google Browser Sync

Google Browser Sync is a very handy Firefox extension that lets you keep more than one copy of Firefox [wdt] in sync across the same or different computers. By “in sync” I mean that it copies over your bookmarks (and bookmarklets!), saved passwords, and even cookies between Firefox installs.

It won’t sync your Firefox extensions, but we can’t have everything.

Also, Google Browser Sync was written by Aaron Boodman, and he’s awesome.
