I'm disappointed Rated 2 out of 5 stars
Fortunately I used IE tab very rarely. Fortunately, because I was always wondering why websites' loading in firefox takes apparently more time than in other browsers on my computer. Now, I saw that I cannot open some websites because firefox was trying to connect with www.superfish.com which is unreachable. The problem didn't appear on other browsers so I started disabling add-ons one by one and restarting firefox. It turns out that websites' loading was taking so much time because of IE tab add-on trying to connect to some server every time I tried to open one. Now it's disabled and web surfing speeded up immediately.This review is for a previous version of the add-on (1.5.20090525).
