I didn't need to do anything -- the missing information reappeared eventually. It seems that it just took a while for it to be recovered.

I am so hoping these come back for me too. So far no luck 😭

Hi taslicco,

Recover user data missing after Firefox update may help you with that. If that doesn't solve the issue, please open a new thread if you haven't already, so we can help you troubleshoot your case fruther.

As a moderator, I've marked the OP's answer as the solution and so we can consider this case closed. Thanks, all!
