Awesome! Rated 5 out of 5 stars

I love this add-on. It saved me a lot of repetitive key strokes when I tried to look for ratings for professor. However, it would be better if this add-on searches more websites.

This review is for a previous version of the add-on (1.6.1). 

currently searches 3 different websites

Hi, thanks for review! By default when you install the add-on, it only searches at one website. However, you can search up to 3 websites with Professor Ratings. To do this, simply go to Tools-->Add-ons-->Professor Ratings Options. From the options page, you can select all the different settings, such as searching for different websites and determining how you want to open the search page (new tab, new window, etc.)
