Migrated from GM(*), no issues so far.

(*) they say "we'll break your scripts" right from the start and didn't even bother to make FF 56 compatible version, FF 57/quantum is required just to install it

monkey see, monkey do

Paired with the fact that it's open source, it's currently a no-brainer to use this on FF

I installed this after upgrading to Firefox Quantum because Greasemonkey 4.0 is basically unusable right now :( I meant to try out Tampermonkey instead, but all that came up when I searched for it was Violentmonkey, which I had never heard of, but I was desperate to get my scripts working again.

I'm so glad I installed this! Not only does it work wonderfully with Firefox Quantum, but it works better than Greasemonkey EVER did, even before Quantum and 4.0. Scripts that I thought were broken now magically work! Odd quarks on certain pages that caused me to have to turn off GM to use those pages are no longer an issue!

It's a breeze to install scripts from around the web (it works with GitHub!) or from your desktop, and it's so wonderfully easy to just make a new script - the built in script editor is awesome.

Do yourself a favor - uninstall Greasemonkey, install Violentmonkey, profit :)

The real time reloading is erroring out. That was the only reason I downloaded this...

Constante desenvolvimento, leve, e ótimo suporte!

Ótima extensão, além de ser open-source.

目前firefox57+版本，这个暴力猴是对脚本安装，运行支持最好的。

Fait parfaitement tourner les scripts en utilisant moins de ressource que les autres

Didn't work for me at all. Tried to import 2 scripts and install. Import failed. Install script failed. Installed Tampermonkey and worked perfectly.

Finally got Mouseover popup image viewer but again no way to manage it so did not work. This one is even worse than Tampermonkey. We need a real working Greasemonkey again.

Not sure if the update to Version 57, or some other compatibility issue broke the script that was supporting an add-on that I was using but the problem is solved after switching to violentmonkey, so I'm going to use this from now.
