Personas plus extra browser opens Rated 1 out of 5 stars

I like what personas plus does with my browser...what I absolutely don't like is that it opens a new tab everytime I open a window.....two windows open, one for personas plus saying to install it. I already installed it and I don't know how to shut this off...it is difficult to uninstall and is not where the uninstall should be.

This review is for a previous version of the add-on (1.6.2).
