I have set up a Firefox Sync account lately. Yesterday, I backed up my laptop but forgot to back up the sync. Now, I can't set up the Firefox Sync service anymore, as my email address has already registered but don't have a sync key to access.
I would like to know how to reset the sync key.
Solved! Go to Solution.
A couple of options, you can reset the sync key which will delete the details on the Sync servers allowing you to start over again. For details of how to do that see the Firefox Sync troubleshooting and tips article.
The sync key should be stored in the password manager of the Firefox version that you originally set up Firefox Sync with. Open the Options/Preferences dialog (for Windows, in the Tools menu select Options). In the Options dialog go to the Security panel and click on the "Saved Passwords" button to open the password manager. In the password manager click on the "Show Passwords" button and in the search field type chrome, that should show your sync key.
Thank you for your prompt reply!
The sync key is not with me in any case, since the backup operation I did was extracting the image of the system 5 months ago, long before I set up Firefox Sync. As a result, there is no saved sync key.
When I get to the Sync tabs, I couldn't see the interface mentioned in the article as from Firefox point of view, I haven't set up Firefox Sync. However, as stated earlier, I already one under my email firstname.lastname@example.org and this prevents me from setting up another one.
Hope these screen-shots can further clarify my situation:
Except that it will delete everthing... incredible! please explain things properly. I'll move to Chrome after this armful trick from firefox. Thanks!
You missed this warning.
"This will erase all of your data stored on the server. New data will be secured by this phrase and then uploaded. Your other devices will not be able to sync until this new Secret Phrase is entered for that device."

The data is encrypted on your computer with the sync key before it is being uploaded to the sync server. So if you lose that sync key then data stored on the server can't be decrypted anymore and becomes useless. If you create a new sync key then all old data needs to be removed and you start with fresh data. It is the same as the Master Password for storing passwords. If you forget the MP then also all stored passwords can't be decrypted and are lost. So make sure that you keep a copy of the sync key in a safe place.
yesterday, 2 guys got into my house (while i was inside) and they took everything. Including both computers i got synced. Now i'm trying to recover all my firefox data and its asking for a sync key. WTF !!! isn't it possible for them to send it to my mail ?? why would you need that.. i already have a username and pass... any way to bypass this or i'm just going to loose years and years of history and password just because someone invented a sync key that con only be reset while erasing all my data ?
The SyncKey isn't saved anywhere except for your PC's that are setup for Sync.You should have made a copy of the SyncKey and stored it in a safe place. Mozilla doesn't have your SyncKey, so they can't email it to you.
