Possibly one point for improvement Rated 5 out of 5 stars

@ajit,
Thank you for developing such a great addon!
BTW, there is one thing to be better. When I fill in words to search in the address bar, and click on the right side to select a new search engine, will it automatically search after the new engine is selected?

This review is for a previous version of the add-on (0.7.17.20130121).
