How do I import my data from Firefox Sync after an uninstall?

I recently uninstalled Firefox and accidentally checked "delete all saved data".

I reinstalled and I am now trying to log in to Firefox Sync so they are recovered since from my understanding the data is saved on the Sync server.


1. Why is it asking me to pair a device? I don't want to pair my phone or anything, I just want to log in from my PC browser and recover my stuff.

2. What is a recovery key and why do I need it?

3. How do I recover my lost data since I can't log in to sync?

  • If you have regenerated your Sync key or reset your Sync password, you can not recover your previous data
  • IMPORTANT - write down your Sync key as instructed in the original set up of Sync
  • if you have another device (computer or mobile) paired to the computer where you are having a problem, you can either:
    1. pair the problem computer to that other device
    2. get the Sync key from that other device

Remember, Sync was never intended for backup. The reason for its existence is to sync-up 2 devices. To back up your Firefox profile, which you should do frequently, to another drive or a pin/thumb drive or other backup media, see:
