Greasemonkey and Tampermonkey enhance a web browser’s capabilities. These add-ons let you choose from thousands of user scripts that modify web page behavior and appearance. With Greasemonkey and Tampermonkey scripts, you can download Facebook and Instagram albums in one click, revamp Pandora’s look and feel, and more.
Browsers don’t vet user scripts the same as most extensions. So, use scripts at your own risk. The scripts featured here have a significant user base and have proven to be relatively safe. However, there’s no guarantee when it comes to overall safety.
Install and Use Greasemonkey
Greasemonkey is only available for Firefox. To download it, visit the Greasemonkey download page on the Mozilla add-ons website.
After Firefox restarts, a new button in the form of a smiling monkey appears in the browser’s address bar. Select the monkey toggle switch to enable and disable the Greasemonkey extension. Select the down arrow accompanying the toggle to modify the Greasemonkey settings and open the Firefox User Scripts management interface.
Install and Use Tampermonkey
Tampermonkey is available for a range of web browsers. Similar to Greasemonkey, you manage Tampermonkey using a toggle switch on the address bar. This toggle turns its functionality off and on, checks for updates, creates your user script, and opens a dashboard where you manage the Tampermonkey settings and the installed scripts.
To install Tampermonkey on Chrome, Edge, Firefox, Safari, and Opera, visit the Tampermonkey website and follow the instructions specific to your browser.

What We Like

Fast and light.

No ads.

Easy installation.
Many websites either recommend or force you to disable ad-blocking software such as Adblock Plus. This script overrides that restriction in some cases and allows your ad blocker to function as expected. It’s not perfect, but it’s better than nothing.

Find More Greasemonkey and Tampermonkey User Scripts
When you’re ready to search for scripts, the following sites are the best starting points. Not every script works across all browsers, so verify the corresponding description and notes before installation.
- Greasy Fork: Greasy Fork is a terrific source for user scripts. It offers a rapidly growing compendium of over 10,000 scripts, a well-maintained and easy-to-use interface, and an active forum. The Greasy Fork Bull**** Filter script makes searching the site effortless. It hides scripts for games, social networks, and those with non-English characters in the Greasy Fork description.
- OpenUserJS: OpenUserJS offers a wide range of scripts. It provides a user-friendly repository with a continually expanding selection.
- Userscripts.org (mirror): At one time, Userscripts.org was the only place to find the best scripts. It went offline and is now available as a mirrored site on a different domain. You’ll find thousands of scripts on this mirror site, and many of these are not safe. Use discretion when downloading from the Userscripts.org mirror.
