Excellent Add-on! Rated 4 out of 5 stars
This is the most awesome add-on I've ever seen in a browser! It really does what is stated in the description and it is very convenient, too. I have only tried several browsers and this one really won me over to Firefox. I mean, there are tabs already and now I can get a preview?! This is incredible!
The only part I do not like is how the preview automatically closes if I click on other different tabs. Everyone has different taste, and I personally, I would like the preview to stay there and only closes when I manually closes it or click elsewhere on the same page. The previews closing just because I switch to other tabs is a negative feature for me.
Great job, though! Keep it up! :D
