It does work in Linux Rated 5 out of 5 stars
I was a little bummed when I first found the extension because it said that it was not compatable with my platform, but then it gave me an option to download it for Windows anyway. Wouldn't you know it? It works great! Just what I've been looking for. I'm not sure why it says what it does, but whatever. I'm running Arch Linux.This review is for a previous version of the add-on (126.96.36.199-signed).
