A proposito de iste extension

Firemonkey is a totally new combined user-Scripts and user-Style manager. While it has similar functions to other user-Script managers like GreaseMonkey/Tampermonkey/Violentmonkey, and user-CSS managers like Stylish/Stylus/xStyle, there are also differences.

Note: None of my extensions contain any tracking, advertising or privacy infringement. They all have Mozilla Open Source licence. The source is clear and accessible by extracting the XPI.

Note: Firefox for Android support is experimental (v2.12+)
