Menu empty in Fx 12 Rated 5 out of 5 stars
Update to my previous appreciation: found that in Fx 12, the menu of Personas Switcher is empty (only a small pixel square appears), not showing my installed personas most of the time. Not sure if this is only happening to me~This review is for a previous version of the add-on (1.7.1-signed.1-signed). This user has other reviews of this add-on.
I'll check this out; are you on Windows? Thanks!
