Seeing that Flock has now entered public beta, and I think it kind of rocks, I wanted to try and sync Firefox and Flock so I could go back and forth. Well it kind of worked.
First I had to edit he Google Browser Sync extension so it would install in Flock. No problems there. Then it did all the work for me and synced everything except bookmarks. Cookies, history and saved passwords all came across with no problems. However, no bookmarks.
Now, if I could only figure out how to get my Firefox bookmarks in Flock. Then I’d be all set.
This is an unofficial extension. I’m not responsible for any quarks and oddities. It worked for me.
