Stylus Extension

Redesign your favorite websites with Stylus, an actively developed and community driven userstyles manager. Easily install custom themes from popular online repositories, or create, edit, and manage your own personalized CSS stylesheets.

Features

* Versatility of theme installation options. Stylus supports installs from popular online repositories. Additionally, styles can now also be installed from .user.css or .user.styl URLs (see Usercss format documentation in our github wiki).
* A backup feature for your entire database of installed styles which is compatible with other userstyles managers.
* An intuitive and configurable automatic update function for installed styles.
* A highly customizable UI, including theming, optional layouts, icon and badge color choices, along with many other tweaks.
* Two different optional code validators with user configurable rules.

Permissions

Stylus uses only a small subset of each permission. As you can see in WebExtensions API documentation or simplified tutorials, there's no way to apply any modifications to a web page without gaining the full access permission to that page. Stylus is mostly used to apply global themes, which is why it requests a global permission. In the future we might be able to implement a more granular approach but it's not exactly trivial.

* Read and change all your data on the websites you visit - required for the style elements to be added into the page, not to access any of your data.

Privacy Policy

Unlike other similar extensions, we don't find you to be all that interesting. Your questionable browsing history should remain between you and the NSA. Stylus collects nothing. Period.

B TB (ID: 000000e42ba62f22) Voted 3 ★ - Updated 01/17/2024 The last update (today, Jan.17th, along with Vivaldi update) broke it. Styles don't load, can't create a new style either (the link in the toolbar button dropdown menu is dead). Will update the rating when it's fixed. Thanks.

小光尼リーロン (ID: 00000017a8110d0f) Voted 5 ★ - Updated 01/11/2024 感謝,我的YT和漫畫站,都多虧這個管理器,搭配很多人寫的各種CSS調整版面,整個簡潔舒服很多

Logan (ID: 000000f0e68ef792) Voted 5 ★ - Updated 11/20/2023 This is one of the MOST IMPORTANT EXTENSIONS I'VE HAD EVER. They allow me to tweak websites, I used this for a 2013 YouTube layout transformation, I've made websites look a thousand times better, I've even wrote my own userstyles before (logan on userstyles world, id 430), basically if userstyles never existed, I wouldn't have as good as an experience on the internet I have now.
