userscripts

Userscripts are small pieces of JavaScript code that can be used to customize the functionality and appearance of web pages. They run in the user's web browser and can modify the content, style, and behavior of websites without altering the original site's code. This allows users to add new features, remove unwanted elements, automate tasks, or change the look and feel of websites to better suit their preferences.

To use userscripts, individuals typically need a browser extension that supports their execution, such as Tampermonkey, Greasemonkey, or Violentmonkey. These extensions act as managers, allowing users to install, configure, and disable userscripts. When a user visits a website for which a userscript is active, the extension automatically injects and executes the script, applying its modifications to the page.

The power of userscripts lies in their flexibility. Developers and users can create scripts for a vast array of purposes, from enhancing productivity by adding keyboard shortcuts to social media sites, to improving accessibility by adjusting font sizes or color contrasts. They can also be used to bypass annoyances like pop-up ads or to integrate external services into web pages. However, it's important to exercise caution when installing userscripts from untrusted sources, as malicious scripts could potentially compromise user data or browser security.
