great addon..however.. Rated 4 out of 5 stars

thanks for a great addon, makes my life a tad easier..however I encounter a problem when I leave the suffix field blank..Im trying to use shift+enter for a wiki search with en.wikipedia.org/wiki/ as prefix and nothing as suffix, but it automatically fills in 'null' as suffix..can this be fixed somehow?

This review is for a previous version of the add-on (0.3.3).
