Just to point that that was me, and I got the problem sorted. Managed to get it back, by revo-ing old install, reinstalling the beta, and overwriting the profile then.

I have to wonder why it always seems the coders go out of their way to screw the end users. That has to stop.

That was very good work. Well Done. Please flag your last post as Solved Problem as this can help others with similar problems. Go to that post and click the 'Solved' button to its right.

Alas, I used a firefox generated password on that temp account, and the password along with the profile is gone, so I cannot do anything.

I am told also that this would have worked, but I have not tried it.

"Start Firefox using the command line (Windows Run box) firefox.exe --allow-downgrade -p That will give you a dialogue box where you can select from the available profiles and set which is to be the default going forward."

I called for more help.
