Hi,
Installed this on FF 38.5.0 (Linux 64bit) but it does not seem to do what it's supposed to.
With FF+ABP+Greasemonkey on http://fuckadblock.sitexw.fr/ there is a blank result http://storage8.static.itmages.com/i/16/0112/h_1452558604_1473791_0acf38c425.png
With FF+ABP+Scriptish the page simply says "ABP is active", so it is detected.
