How to get back my account details

Hi, if you are asking about Firefox data such as bookmarks, if you were using Sync on your old device, then some of your data probably is stored in the Sync cloud and could be shared with new devices when you sign into a new installation of Firefox.

Important: do not Reset your password for your Mozilla account, as they will wipe the saved data in the Sync cloud.

Why are you reinstalling Firefox? If there is a problem with your Firefox, you can start a new question here:

Notes:

• Firefox does not require an account number to install. Maybe try again using a download from the official site: https://www.mozilla.org/firefox/all/desktop-release/.
• If the problem is that you are connecting to your Mozilla account (after installation) to set up Sync, you may need a code that was sent to the primary email address on your account.
