Rated 5 out of 5 stars
Thanks again to Evan Eveland, for this wonderful extension that worked so well in past versions. However, it's broken now, at least in FF21 on Windows 7, 64-bit.

Such a simple, yet useful addition! I've used it for years without a hitch. Should be standard equipment in Firefox.This review is for a previous version of the add-on (0.5.0.5).
