    It's open-source (unlike Tampermonkey) and works in Chrome (unlike Greasemonkey). Got a script running in less than two minutes. What more do you want?

    ViolentMonkey is lightweight and faster but lacks features needed to manage hundreds of userscripts and its developer isn't willing to add any of them. If you’re a power user, stick with TamperMonkey or choose another alternative.

    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.
