Rated 1 out of 5 stars

Apparently not configured to work for any US ISP's as I don't see any listed on the set-up options menu and doesn't appear to work with AT&T. If that is the case it should be mentioned in the "long description" to save from wasting time downloading and installing

This review is for a previous version of the add-on (1.1.0.23). 

If your ISP isn't after "The currently compatible ISPs are :", it's isn't compatible. ;-)
However, you can go to http://extensions.geckozone.org/Minimeter-en#askmodules to see how to ask for a new module.
