Description
Notes
I created this userstyle because the existing styles and extensions don't actually work on all websites. For example, the StackExchange network reenables hyphenation for some parts of the site.
Those site uses a technique that defeated previous methods. My userstyle uses a 20x more powerful method that should help you regain control for good. A technical explanation is on GitHub.
