Cannot use my old firefox sync account after reinstalling

After reinstalling firefox I can no longer use my old Firefox Sync account. I am told that there is no such account here https://accounts.firefox.com and I created a new account, with the same e-mail as my old account.

After some research I was able to find this https://account.services.mozilla.com/ in which I can login with my old account.

My problem now is that I want to retrieve the information that I had in my old sync and I can't find any way to do it.

Also, because I was experiencing severe performance problems using firefox, I deleted some folders in my machine related to Firefox (after uninstalling) including what seemed to be the profile location for firefox.


What is really important for me is: How do I retrieve my old Firefox Sync account data or synchronize it with the new Mozilla account?


Thanks, V

Chosen solution

hello, firefox 29 and upwards is using a different sync system which isn't compatible with accounts set-up in older versions.

in this case you'd probably have to use a workaround and download the prior firefox 28 version, disable automatic updating for the moment (in options > advanced > update), link it to the old sync account (with username, password & recovery key) and upgrade after you have successfully restored your data this way...

Install an older version of Firefox Sync your Firefox bookmarks, history, passwords and more
