I created an account just to rate this POS add on. For over a year and a half I couldn't figure out why my tabs were all changing to "about:blank" no matter how many open - all of them. I figured it out it was this POS home button. I had to uninstall and reinstall Firefox to remember - FF doesn't have a home button. The add on used to work but after some update it started malfunctioning. Don't install it. Also - why the hell doesn't FF have a home button anyway?
