Hi. Before to re-install Windows, I saved my Firefox Sync Key. After windows installation, I can't to access my firefox sync account to get my bookmarks! It says: unknown account, register! But I have a KEY, I need my bookmarks back!

Help me, please, to recovery my bookmarks back! Thanks.

You must have been using a quite old Firefox version if that version still used a distinct Sync key. Firefox 29 and later no longer use a specific Sync key, but derive the Sync key from the password of the Firefox Account that you use to log in to this account.

You would need a Firefox 28 version to connect to an old Sync account that used the Sync key.
