Rated 5 out of 5 stars

Neat features, simple intuitive interface, and a wonderful use of the add-on idea!

But ... the latest version (0.73.16) does not work properly with PowerPC Macs and FireFox 2.0.0.18 (at least) -- the contextual menu doesn't appear when you click on the status area, and the SSN does not show in the status area at all.

I've downgraded to version 0.73.12 which works flawlessly (altho it is a bit slow to update when first launching the browser.... v 16 seems to fix that delay, but breaks everything else!)

This review is for a previous version of the add-on (0.73.16).
