Puntuado con 1 de 5 estrellas

I am using FF 18.0.2 and it does not work....I tried it on this very page (add-on page for Prostetnic highlighter), the text gets highlighted ok, but when I come back to this page the highlight is not there....I then tried it on different web sites...same thing...once you leave the page, the highlight is gone.

Esta valoración es de una versión anterior del complemento (initial.rev530.1-signed.1-signed). 

Persistence of highlights works on mine

It says you're not using the latest version (of the highlighter): "This review is for a previous version of the add-on (initial.rev530)." Try the current version, if possible. It should re-highlight, although there are some glitches (which I am working on) that will cause it to also highlight other instances of the same text.
