Can you still view your old profile?

Have you ever used the FF beta?

I did not even enable this update !

What did you mean by this?

Look on your desktop. Do you see a folder called; Old Firefox? Look inside. Look for the folder with the latest creation date.

that desktop folder only has the current data since the update was done 2019/05/21

there is no profile info in the prior to that date

Look inside the folders. Does it have your profile inside? Compare the file list with the current profile folder.

there are no profile with date before 21/05/2019 , they have all gone

That means the folder was created two days before, and is likely your missing profile.

I have the same problem and I don't see any clear path posted as a solution Going back to 66.0.5 restores all of the missing bookmarks, password and configuration Is this a MAC OS problem or is it on all platforms - this seems to be

a bad release
