At last, I’ve found a bookmarking solution that syncs my Firefox bookmarks between computers. The Bookmarks Synchronizer extension works like a charm. The version on the Mozilla addons web site isn’t compatible with Firefox 1.5 so be sure to use this link.
Has anyone found a better solution? Next I’m after something that’ll allow me to integrate my Firefox and del.icio.us bookmarks so that I’m not constantly checking in two places. Suggestions welcome!
