Disable JavaScript is a web extension designed for Firefox and Chrome that allows users to manage JavaScript settings on a per-domain or per-tab basis. Users can easily toggle JavaScript on or off, set default states, and manage a list of blacklisted and whitelisted domains. The extension also supports shortcuts and context menu items for quick access to these functions, enhancing user control over web content execution.

The extension is open-source and respects user privacy by not logging any personal data. It offers features like manual domain addition and automatic handling of subdomains. With a straightforward interface, it aims to provide a seamless experience for web developers and users who wish to improve their browsing security or performance by selectively disabling JavaScript.
