Can't use my default profile after downgrade...
I use Manjaro Linux. Since i cant use webgl in the last version of FF (updated by me today / tried to force webgl in settings) i decided to downgrade it to previous version... and i cant use my old profile - even if i chose it in profile manager after restart i got warning about using an older version of FF and i can onlu quit or create new profile... what i can do ?

Already found solution for this... 1) For problems with using profile at older versions run firefox with -allow-downgrade. Thats all. 2) For problems with WebGL: Open about:config and set security.sandbox.content.read_path_whitelist to /sys/.

Unfortunately your profile has been updated to work with the newest version you had installed and can't work backwards, so you'll have to create a new one.
