Just recently, I started getting this message on my desktop. It's very random, and easy to get off the screen, but it WILL come back.

Can anyone tell me what's causing this message, and how do I permanently get rid of it?

??? I'm running a new download of Firefox, ver. 113.0.2. Nothing special.
So how do I get rid of that annoying message?

Well, it mentioned a file that was missing, but, on my PC it's not missing.
In fact, there appeared to be two of them. ??? But then, I'm no software Guru!

In the error box, it seems to me to be asking me to create a new profile. I'm not sure I know how to do that,
other than go through all the options menus and fill in all the blanks. ???
Maybe, if there was a Tutorial on "How to create a new profile in Firefox".

In my previous post, I stated that I found TWO folders where there probably should be just one.
Not knowing which one I should delete, I just deleted them both.
Then I transplanted the same folder from my Main PC to this one. I hope that helps.
So far, Firefox is operating normally, and I still have my Bookmarks Toolbar, etc.

Since the errant message was very sporadic, only time will tell, if I have a FIX or not.

BUT, being the eternal Optimist, I'm going to call it FIXED.
Thanks for all the inputs!
