Almost There Noté 4 sur 5 étoiles
I noticed a new release of Personas Plus and decided to give it another try, mainly because I need the custom personas option to test personas before submiiting them. In the past Personas Plus wiped out customizing on every Firefox restart. The problem may have been only on Macs, but persisted over several OS and many Fx releases.
This works better. It wiped out my added toolbar, but after I rebuilt it subsequent restarts left it in place. Mysterious, but play Twilight Zone theme and move on.
