Hello,

My version of Firefox started to malfunction.

Found the latest version of Firefox available, and installed it.

Resulted in total loss of data, I lost all bookmarks, passwords, and add-ons.

A folder called "Old Firefox data" was created on my desktop.

Is there still a chance to recover my data?

Why was all data lost?
