Violentmonkey

Violentmonkey is a browser extension primarily designed for the Firefox web browser. Its core functionality allows users to run custom user scripts on web pages. These scripts can modify the appearance of websites, automate tasks, or enhance browsing experiences in ways not natively supported by the browser. The extension acts as a manager for these scripts, enabling users to install, enable, disable, and configure them.

The "violent monkey" name itself is a reference to the concept of user scripts being able to perform powerful, sometimes disruptive, actions on web pages, akin to a monkey enacting forceful changes. Users often employ Violentmonkey to block advertisements, change website layouts to their preference, or add new features to specific sites. The development and maintenance of the extension are typically handled by a community of developers, with its source code often available for public inspection. While the extension itself is not malicious, the user scripts installed through it can potentially pose security risks if sourced from untrusted locations. Therefore, users are generally advised to exercise caution and only install scripts from reputable sources.
