doesn't work for me, I made the .js dir in my users directory and my firefox profile directory (just in case)
Fx 24.0
Win Vista SP2

This review is for a previous version of the add-on (1.10.1-signed). 

Hi rickdog! In Windows, the directory name needs to be /js/ (without the .). In Windows 7, for example, the filename+path should be something like: C:\Users\<username>\js\google.com.js

I hope this helps. I am happy to troubleshoot with you.
