NotScripts: Blocks Unwanted JavaScript

A free and open-source browser extension for Chrome and Firefox, blocking unwanted JavaScript from running on web pages with customizable script blocking based on patterns.

What is NotScripts?

NotScripts is a free and open-source browser extension available for Chrome and Firefox that allows users to block unwanted or unnecessary JavaScript from running on web pages they visit. It gives users more control, privacy, and security over what kind of scripts are allowed to run in their browser.

The extension has a simple interface that allows you to create custom filters to block JavaScript by URL, domain, or script content pattern matching. For example, you can block all scripts from a specific tracking domain, ads provider, or matching a certain pattern that identifies unwanted scripts.

Notable features of NotScripts include:

  • Open-source code and publicly available blocklists for transparency.
  • Simple rules interface for easily creating custom JavaScript block filters.
  • Supports plugins and custom userscripts for additional extensibility.
  • Detailed activity log showing every script run on sites.

By blocking unnecessary JavaScript with custom rules, NotScripts can speed up page load times, save bandwidth usage, and prevent unwanted tracking/mining scripts from websites you visit. The granular control allows you to find an optimal balance between functionality and security/privacy.
