A Firefox extension that enables users to install and run user scripts for on-the-fly changes to web page content, allowing customization and enhancement of web pages.
Greasemonkey is a popular extension for the Mozilla Firefox web browser that allows users to install user scripts to make customizations to web pages on the fly before or after the page loads in the browser. It provides a way to modify the user interface and behavior of various websites to add extra functionality or fix issues.
Some common uses of Greasemonkey scripts include:
Greasemonkey scripts use JavaScript and the browser DOM to make changes, so they can be very powerful but do require some programming knowledge. The Greasemonkey community has a large selection of free user scripts to add capabilities to popular sites like YouTube, Google, Amazon, and more. The scripts are installed within Greasemonkey's dashboard and can be enabled, disabled, edited, and removed as needed.
By customizing and enhancing websites to best fit their preferences, Greasemonkey provides Firefox users with a way to personalize their browsing experience for improved usability and productivity.
