After a very long time of having this addon installed, I finally figured out it was the cause for google search results freezing up.
Whenever I would search something in google, and click a picture in the results, the whole page would freeze and after a few seconds I get that yellow alert bar "A web page is slowing down your browser. What would you like to do? [Stop It] [Wait]". Today I got fed up with having to deal with that, so I turned off 1 addon at a time to figure out which one was causing it, which is this one of course.
So much for your tagline "Browse without interference on all sites."
