[tool] MozBackup - copy your Firefox profiles
I'm setting up a new dev computer and used MozBackup to migrate all my Firefox
extensions. It goes better than that - it also supports copying the extension
settings, saved passwords, history, and a bunch of other stuff. It was kind
of spooky when I restored it on my new computer and (since I'm using the SessionSaver
extension) seeing all my tabs restored exactly like the old
 It also supports Thunderbird, but I don't use that.
