please donate Rated 5 out of 5 stars
I love this plugin and I have donated to the developer's fund to create a 4.0 version.(the link is in the developer comments under the image gallery). I use this plugin all the time for research and its the main reason I use firefox over other browsers.This review is for a previous version of the add-on (2.4.2). This user has other reviews of this add-on.
