I only use it on a couple of websites, but it really makes visiting them more enjoyable.

Thank you so much for this add-on: With this add-on I could change the colour of visited links in firefox. All other things didn't worked (like userContent.css etc).

Easy to use and very good

2025.05.06 added: It seems that the problem is a bug of Amazon Vine Helper v3.x. So, I've rated Stylus as 5 stars.
Initial: Stylus interferes Amazon Vine Helper when Stylus is the latest version 2.3.14. So, please modify it. When it is 2.3.13, it does not interfere Amazon Vine Helper.
