Hello testate, see : Where can I find my Recovery Key?

thank you

That is for finding the recovery key off a computer. I need to get it off the MOBILE device.

I would also like to know this! I have two Android devices using firefox sync. I've had to reinstall my desktop OS, and now want to set up firefox sync on the desktop machine again. Unfortunately I've lost my recovery key. Is there no way to retrieve it? I don't want to lose all my synced data!

hello, have a look at this extension: https://addons.mozilla.org/mobile/addon/aboutsynckey/

Thanks, but that extension only works on versions 8.0a1-11.0a1. I have version 19.0.2!

oh sorry, i didn't consider that & look close enough :-/

forum member cor-el has created a modified version of the addon which might work reportedly, see https://support.mozilla.org/en-US/questions/942893#answer-384736

I could not find a way to do what we wanted to, however, the problem was solved for me in a different manner.

See: https://support.mozilla.org/en-US/questions/946579?esab=a&s=&r=1&as=s

It syncs using the info from you phone. The tricky part was the sync option is not in firefox, it is in the operating systems settings.

Thank you testate! That solves it!

I don't think this firefox sync software was thought out too well.

You can look at this version of the about:synckey extension that I have modified to show the sync key in current Firefox versions (desktop and mobile).
