Not clean at all ! Rated 1 out of 5 stars

it is suspecious add in !
Impossible to clear cache and history browser after spliting tabs ! there is always history site in navigation toolbar of the splited tab!
So in my mind, this is non clean nor simple add-in, in contrast to what is said in it's main page !

This review is for a previous version of the add-on (0.6.2009050101).
