Tampermonkey is the world’s most popular userscript manager, and with this extension users of Chrome browser can dramatically enhance the functionality of various websites by finding, downloading and activating a large number of “mini-apps” coded in JavaScript that can run in the background and directly manipulate running and visual design elements of websites you frequent.

The main purpose of Tampermonkey is to be a middle manager between the loaded websites, and custom user scripts that can actively change the way they are rendered and executed. These scripts can change anything from visual elements of websites to adding a brand-new functionality to them. For example, the appscripts can change the way forum posts are displayed, add the ability for real-time refreshing, add new functions to websites such as the “download video” button for YouTube, and many others.

To manage such wide variety of scripts, the addon comes with a fully-featured script manager with tools for sorting, editing, script synchronization via popular cloud hosting solutions (Dropbox, Google Drive, Chrome Sync and others), backup and restore via the same cloud hosting solutions, and easy to use interface for finding, selecting and enabling/disabling scripts. Each of the installed scripts can be deeply customized, with full support for editing code.

As of today, ithosts a wide variety of scripts and attracts over 10 million users from the entire world. If you are curious to see how your favorite website can be customized, or you simply want to enhance your general browsing experience, take a look at the incredible capabilities of the app.

Be aware, that Tampermonkey user scripts are also sometimes called Greasemonkey scripts, which is the name of another script manager service for modern browsers.

Installation and Use

Tampermonkey is one of the most advanced and intricate Chrome extensions you can install on your home PC or laptop. Once installed it will appear in your toolbar as a new monkey-shaped icon but activating it will not produce just a simple easy to use interface, but instead a fully-featured script manager that holds a wide variety of tools and options.

To properly get a handle on all the functionalities this app can give you, some time will be needed to learn about its user interface, tools, and features. Even loading a simple script requires a procedure that will require you to take notice of several tools required to activate it.

The user interface of Tamper monkey is separated into individual tabs. The default ones are Help, Utilities, and Installed Userscripts, but you can open up additional tabs by choosing to edit individual scripts. Scripts can be edited either directly with code, or with some of the built-in options for general usage, appearance, script update timings, and more.
