Firefox update deleted profile

I sometimes receive notification that Fx can't update automatically and I need to download the update. Twice now, the update has deleted my profile on drive D, and replacing it with a new one on the default C: drive. Settings, options, addons all GONE! I finally had to restore my entire system from a backup. What's going on and how can I prevent it happening again?

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

Was it removed, or the browser can't find it? Use the file explorer and look.

There was no folder on my desktop at all. I had one the first time this happened but I did not have the patience to figure it out - there was no notification in the program, nor a readme in the folder.

Your second question: The profile folder was still there but completely empty. I always create profiles for FIrefox/Thunderbird on partition (D:) so they get backed up daily. Win10 image is created weekly. These usually save me a lot of time. Restoring a Fx profile is not quite that simple of course...

Did you look on the D: drive that the profile is really gone as this can merely be a problem with profiles.ini and a new profiles.ini got created and a new default-release profile in the default location ?
