I recently reinstalled Ubuntu. I opened Firefox preferences and tried to add my sync account.
I selected the option saying I didn't have my device with me, and proceeded. Next I entered my details and saw that something called a 'recovery key' was needed. I didn't remember seeing this before (and I've been using sync since it was called weave), so I clicked "Don't remember" and then "Generate new key".
It said it was succesful and that it would start syncing. But none of my data came through. I started getting worried. I searched the Internet and found this http://support.mozilla.org/en-US/kb/Replace%20your%20Sync%20information.
So it looks like all my years of data online has been removed without warning me. Sure, I should have backed up the data (and in fact I do have an older backup), but this still shouldn't happen without warning me. It's a big shock.
Has this happened to anyone else? Is there anything I can do about this?
