Hello! After installing Firefox in a different OS, I logon to Sync and I've noticed that my Top Sites don't appears like I left them (it took me a long time to have them organized). When I came back to the other computer (main one), Sync reorder the Top Sites like in the new OS and almost delete all the ones that I had pinned. Is there a way to do a rollback to an specific date? It doesn't matter if I lost some other data. Thanks. Kind regards.
