Tampermonkey

Its a great idea, and I have used it on Chrome, but it doesn't work well on Edge. Gonna have to give it one star. Needs work on edge.

This is a great Chrome extension, and I'm really excited it's coming to Edge. The performance isn't quite what it is on the Chrome version yet, but there's no reason to think it won't get there after a few updates.

This is a great product and I hope that it continues to be developed for Edge. Some issues that I've encountered with it are that the scripts can only be downloaded instead of installed from the respositories. Also for some reason, it causes some website pages to download instead of viewing in Edge. Like Newsarama.com and tomsguide.com. I have to turn it off to view those sites.
