I'm glad it works well for me on Firefox 57.0! It gets the job done when I wanna use a userscript on my Firefox browser such as webm-looper-userscript :)

solo me facilita muchas aplicaciones de trabajo gracias

Terrific, you can just customize anything on any website!

There are improvements to be made and features to be recreated but the effort going in to redeveloping Greasemonkey for webextensions is for me so far successful. Some quick modifications were required to scripts that I had utilizing per user options but other than that I've had no issues.

It works perfectly, and saves a lot of time.
