Where can I find my firefox mobile sync key so I can add a desktop (old desktop crashed)?

more options

I'm reinstalling Firefox w/sync on my desktop. I entered the sync key from a printed report that was issued when I first set up sync. I used the dialog to enter account info, password and sync key. It was rejected so I went to my Android device. It is connected to sync, but I cannot find the sync key or any way to tell it to add the desktop computer. How can I do this?

There's no built-in way to use Firefox for Android to display your sync key or add a device to your sync account. We're working on adding that feature to a new version.

For now, you can go to limpet.net/key using Firefox for Android to install an add-on that will send or display your sync key.
