Good! Rated 4 out of 5 stars

Good add-on, already a must-have. Also, I like options about the location of progress-bar and hovered links. However, it needs a max-width : when hovering a long link (like a bookmarklet with a lot of js), it takes an infinite place and is unusable. Except that, perfect, thanks!

This review is for a previous version of the add-on (2010.09.29.00).
