Rated 5 out of 5 stars

ghumdinger - There is another extension that lets you set fonts for individual sites, called Stylish: https://addons.mozilla.org/en-US/firefox/addon/stylish/ Actually it lets you use CSS to do all sorts of modifications to websites, not just changing fonts, but anything CSS can change. So you don't need to request that feature for this extension, since another extension already does that.

This review is for a previous version of the add-on (2.1.2.1-signed).
