Personas Plus Rotation Option

https://addons.mozilla.org/en-US/firefox/addon/personas-plus/

According to the description for this addon, I SHOULD be able to enable an option that causes my personas to rotate at certain intervals, however after looking through the context menu that pops up when I press the add on button itself, and going through my add ons manager I am unable to find it.

I also installed this add on to see if it would help, but it seems to have done nothing at all.

Have you tried contacting the developer of Personas Rotator about it?
