But now back to the topic at hand: If you feel that this extension
  • helps when you're browsing your favorite sites or
  • it makes you more productive at work or
  • maybe just simplifies a online game you're playing
then please consider Thanks for your help.

As you may know, in order for Tampermonkey to actually do something, you need userscripts.
The new Userscript.Zone website can help you as it allows you to search for userscripts by URL, domain or search term.
So give it a try!

Below there is a short overview of some of Tampermonkey's key features. Maybe you'll find something useful. :)
A list of other script sources can be found here.

Easy Script Access

Tampermonkey makes it pretty easy to manage your userscripts. The Tampermonkey icon at the upper right shows the number of running scripts and a click at it shows what scripts do run and what scripts may run at this page. ( video tutorial)

Script Overview

Tampermonkey show a clear overview of the scripts that are installed. You can see when they were updated the last time, if they do have a homepage, you can sort them and many more... ( video tutorial)

Configurable Setting Diversity

You can choose between three different levels for the settings page. This way rarely used options can be hidden to keep the page evident. ( video tutorial)

Automatic Script Update

You can setup how often the scripts will be checked for updates. No more bugs due to outdated userscripts. :)

Only the paranoid survive! Blacklist all sites that never should be accessible by a userscript.


In earlier times a lot of userscripts were written for the Firefox userscript manager called Greasemonkey (<= 3.x), that's why Tampermonkey offers a compatibility layer and tries to detect the necessary settings automatically.

Script Synchronization

You're using more than one browser, one at home and one at work? Simply enable Tampermonkey's sync feature to synchronize your scripts.

CodeMirror Editor

Syntax Check with JSHint

Your script doesn't work? Tampermonkey's syntax check might find the issue... :)


If you're not happy with Tampermonkey (this is unlikely to happen, but who knows ;), then you can remove it at the browser's extension page.
