Where can I enter my Firefox sync recovery key?

Firefox Sync no longer uses a recovery key. Sync your Firefox bookmarks, history, passwords and more

What but I just got my key today why was I not notified... :/

The "Recovery Key" was last used in Firefox 28.

Firefox 29 - released on April 29, 2014 - and later versions use a different method of data encryption, which eliminates the need for a "Key" to be inputted by the user.

hello, you could try this "hack" to get a new firefox version to connect to an old sync account: enter about:config into the firefox address bar (confirm the info message in case it shows up), right-click somewhere in that page & create a new string preference named services.sync.usernamewith a value like fake.

afterwards you should be able to connect to the old account through the firefox options > sync panel. if this worked and you could import your data successfully, please migrate to the new sync afterwards: Sync your Firefox bookmarks, history, passwords and more
