Breaks other extensions Rated 2 out of 5 stars

Works in FF4 -- but breaks functionality of both the "Search Box Sync" and the "Conform Searchbox" addons. In the meantime, I recommend "Googlebar Lite" instead -- does highlighting, adds search term buttons, and works with "Search Box Sync".

This review is for a previous version of the add-on (2.4.2).
