Like it BUT... Rated 3 out of 5 stars

I like heaps; great idea, BUT it keeps crashing the 3.5.x versions of Firefox that I've been using.
Don't know if it's some incomapatibility with another add-on. Don't have time to sort it out. Don't know when it's gonna go pear-shaped. Maybe need to configure another modifier key+mouse combo?
Needs an upgrade...

This review is for a previous version of the add-on (1.0.0.12).
