My phone suffered an unclean restart to which Firefox kept crashing on open, I reinstalled the app succefully and now opens okay; however it won't sync with my pc login, it keeps asking me to sign in to firefox on another Device to complete setup, though I am logged in currently on my pc account I can't get it to complete even after multiple attempts.

Hi Drieka,

I understand you are having issues with syncing between your pc account and your phone.

If you have access to your PC please check to see if your phone is synced.

  1. Click the Open menu (top-right of browser window)
  2. Click Options
  3. Click Sync
  4. To see if your device is already synced, click Manage devices
  5. If your device is not showing on the list, click Connect another device
  6. Add your phone number

Try restarting Firefox in Safe Mode to disable any 3rd party extensions.

  1. Click the Open menu
  2. From the drop-down menu click Help
  3. Click Restart with Add-ons Disabled...

I've done the above, the problem I'm having is when I log in on the mobile device and have put in my Authentication Key I get the page telling me: "Sign in on another device to complete setup." Which I can't get passed despite being logged in on my browser (PC) and having sent the add device link from it.

Hi Drieka,

Does the screen attached appear similar to yours where you are stuck? Or does it not say This Firefox is connected?

Exactly as your screenshot, I tried logging out and back in on my PC to try and prompt it to continue but to no avail, that is the screen its stuck on.

If you get the screen that this Firefox is connected then you have finished the Sync setup on that device and Sync should work.

On a desktop device you have the option to check for Syn error logs, but I don't think that this feature is present on mobile. On mobile you can try to disconnect Sync and reconnect to Sync.

But it doesn't have my details under settings, it just asks me to sign in again repeating the process. It also doesn't list my mobile on the list of devices, only as a web session on my account.
