It is indeed super lightweight. A nice advantage to being on Firefox, as it's not available elsewhere.

I am looking for an alternative to Tampermonkey. FireMonkey looks promising. However, it does not support importing a .zip created by other managers. Therefore, I use Violentmonkey instead.

I've read https://github.com/erosman/support/issues/236

Since the only userscript managers that worked in Firefox Android (beta & nightly through custom collection) are this and tampermonkey, I choose this becase it's open source and more lightweight. Good job

This addon is nice, it's pretty simple to write js scripts with it, however I've struggled to write css scripts. I would assume that it shouldn't be too different from normal css, but trying to port my css scripts from stylus to firemonkey hasn't worked. There might be something simple I'm missing but I haven't been able to figure out what it is. I think the css documentation could be improved to make it easier to write css scripts.

É uma extensão muito boa para se utilizar tanto na Área de trabalho quanto no Firefox para Android, só não estar funcionando a exportação das configurações da extensão e tradução, quando utilizado no Android.
Somente a importação das configurações funciona no momento.

Lightweight, fast and effective. It does what it claims with excellence.

The only extension that uses the built-in userScripts API, as far as I know, which makes its approach far cleaner than other choices.

What an awesome extension. I was looking for something to manage a few custom userscripts and this is the best option right here. Lightweight, smooth, and reliable. Thanks for spending the time and energy developing this. I appreciate it.
