Hi - I just moved files to a new computer using PCmover. It did successfully move Firefox over including bookmarks and themes. However, I am unable to use any of my themes even though I click on "Enable" (I did try a couple of different themes). I had Personas Plus previously installed on my old computer to use to change themes but, while it is there in the list of Extensions, I can't click to enable it. Any ideas? Thanks in advance for the help!
