I had to format my computer once again. But this time when trying to get all my firefox data from the sync server, nothing happened :(
I've tried updating firefox. reconnecting to the sync server a couple of times. But as the title says, nothing has happened.
I fear that somehow all my data has been whiped, but I have no clue why it should have done that.
I think my old FF was running v4b7, but I can't say for sure.
I tried adding some bookmarks, and then replacing all local data with the sync data, and I got all the new bookmarks back. So sync works again, it just doesn't have my old data.
I considered using x-marks a couple of days ago, seems like it was a STUPID idea to put it off..
still, if you have any suggestions, I would be very happy to hear them!
found a thread on the firefox support forum as well: https://support.mozilla.com/en-US/questions/772759
