How do I convert the old sync key (12 characters, no dashes) to the new sync key (31 characters, 5 dashes)?

My sync key used to be 12 characters, no dashes (xxxxxxxxxxxx). After uninstalling and reinstalling FF 3.6.13, Sync 1.6.1 refuses my 12 character sync key. I discovered, that sync keys for all users have been switched to 31 characters including 5 dashes (x-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx). How do I get the new sync key? I have no PCs connected to Firefox Sync anymore but Firefox Home and 360 Browser on my iPhone sync successfully. Unfortunately on the iPhone I cannot display the currently used sync key. Is there a way to convert the old sync key to the new one? I need the bookmarks saved in my Sync account. Thanks for your help!

I had the exact same symptoms you did. Here's my solution: I installed an older version of firefox sync (1.4.something, I think) and then added my account using my old short firefox sync key. When trying to sync, the outdated addon said that in order to perform the sync, it needed to be updated. After updating, I was still signed in, but now had the added feature of seeing my new long firefox sync key which was compatible with FF 4b, etc. Everything is working smoothly now and my computer is syncing correctly.
