Top marks for a great tool, and for responsiveness Rated 5 out of 5 stars
This has got to be one of the most useful add-ons for FF. It makes searching, referencing, translation, etc., extremely easy within the page you're reading. It has become such an essential (and addictive) tool to the extent that I resisted upgrading to Firefox 5.0 because this was one of the add-ons that was incompatible. Luckily I thought of emailing the developer, and got an instant response pointing me to a work around. Full marks!This review is for a previous version of the add-on (8.2).
