Despite me liking Internet Explorer 9, there are many features of IE I do not like. One of them is frequently freezing up. IE9 freezes up more often than other browsers but the recovery method is quite good. Another feature is the "pin to taskbar." I find it pointless as I keep most of my favorite pages in the favorite bar (area circled in black).
Another thing is that most plug ins do not work in the Window launched from pin tabs. Thus, I do not know whether a site I am visiting is safe or not (I use WOT and Norton Safe Web). Also, my password manager (Norton Identity Safe)does not work as well.
