    uBlock Origin

    uBlock Origin

    An efficient blocker for Chromium and Firefox

Furthermore, the advanced mode allows uBlock Origin to work in default-deny mode, which mode will cause all 3rd-party network requests to be blocked by default unless allowed by the user.

    Ruler AI

    Ruler AI

    Centralize and sync AI coding rules across tools and projects

Ruler supports nested rule loading, allowing teams to define context-specific instructions for different parts of a codebase. It also manages MCP server settings, automates .gitignore updates, and provides simple commands to initialize, apply, and revert configurations. ...

    cssnano

    A modular minifier, built on top of the PostCSS ecosystem

    ...Our preset system allow you to load cssnano in a different configuration depending on your needs; the default preset performs safe transforms, whereas the advanced preset performs more aggressive transforms that are safe only when your site meets the requirements; but regardless of the preset you choose, we handle more than whitespace transforms! Optimizations range from compressing colors & removing comments, to discarding overridden at-rules, normalizing unicode-range descriptors, even mangling gradient parameters for a smaller output value! In addition, where it's made sense for a transform, we've added Browserslist to provide different output depending on the browsers that you support.

    JSS

    JSS

    An authoring tool for CSS which uses JavaScript as a host language

    ...If you’re interested in playing around with JSS, you can use an online code playground. Try a Hello World example on CodeSandbox. JSS generates actual CSS, not Inline Styles. It supports every existing CSS feature. CSS rules are created once and reused across the elements using its class name in contrary to Inline Styles. Also, when DOM elements get updated, previously created CSS rules are applied. JSS generates unique class names by default. It allows avoiding the typical CSS problem, where everything is global by default. It completely removes the need for naming conventions.
