After installing this add-on I couldn't go to Firefox complement to see my already installed add-ons, I have this error every time I tried to access the page:

about:neterror?e=unknownProtocolFound&u=rdf:#$Lk8Zn1

Some virus behaves like this, so I have to uninstal Firefox just to be sure it was not a virus. Finally, I had to setup again Firefox as it was before.
