Works just fine for me! Rated 5 out of 5 stars
I don't know about the problems others are having, but the update solved the problem for me. It also fixed the particular problems it caused with TaxMix Plus, an essential for me. Afterwards I upgraded to Firefox 17.0.1 from 16.0.2; everything still works fine.This review is for a previous version of the add-on (18.104.22.168.1-signed).
