How do I use additional for Firefox?
This review is for a previous version of the add-on (1.0.3).The originator of this add-on did not include support for FireFox. I don't really know how to make it work in FF. I wish I did. I find myself making typos in FF because I am so used to AC in TB. Wish I could fix it ...
