I own two computers, one Mac and one PC (see my sig), and use Firefox as my primary browser on both machines. What I am curious about is whether or not there is a good way to sync my bookmarks between my machines. I have, in the past, just done in manually with the occasional export/import. But I will add new sites (or delete old ones) to one machine and not the other fairly regularly and would like some way to keep both of them up to date. Any helpful advice will be appreciated.
