I’d like to take this opportunity to recommend Glyphobet Browser Sync as an alternative to Google Browser Sync. Here it is:

rsync -av --delete user@remote.host:~/.mozilla/ .mozilla/

Some of the great advantages to Glyphobet Browser Sync include the fact that all your browser settings are transmitted securely over SSH, are password protected by UNiX file ownership and permissions,¹ and do not require the presence of a large corporation with a dubious privacy & security track record. Plus Glyphobet Browser Sync takes advantage of industry standard technologies, just like MacOS X.
