I've been using this add for a week and it works great

First off I'm just going to say that Mozilla really should be clearing out old reviews because virtually ALL of the one star reviews are from about six years ago, since when the issues from that time have most likely be resolved.

I searched and found this extension for one purpose only. And that was to remove the idiotic number of link styles in Wikipedia articles. Some of the leads there contain so many links the link style makes the articles completely unreadable. This works like a charm. Just search Google for the css code to remove link styles from any page, insert that code into this extension and VOILA! Readable Wiki pages. Love it! Thanks to the developers of this fantastic extension!

Thank you so much for this plugin, It's so useful! Every week, I'm happy to use it to tweak a few things, hide annoying marketing banners or adapt theme colors to help with my eye strain.

Stylus (unlike Stylish, which was known to capture users' browsing data at some point) is focused on user privacy, is completely open-source, and is maintained by an active community. So, I would highly recommend using this extension if you want to customize the appearance of websites you use.
