Tampermonkey is a browser extension port for Microsoft Edge that is currently available as a preview for Insider Build versions of Windows 10.
Microsoft added support for browser extensions in Microsoft Edge when it published the Anniversary Update for the company's Windows 10 operating system.
While the output is rather low right now -- there are a good dozen or so extensions available on the official store -- extensions will make Edge more usable and attractive in the long run.
Users can install ad blockers and other useful extensions right away. Those who run an Insider Preview version of Windows 10 may also install extensions that are available as previews.
One of those extensions is Tampermonkey.
Tampermonkey for Microsoft Edge
Tampermonkey is a port of the Google Chrome extension of the same name (also available for Firefox). It adds capabilities to Microsoft Edge to run userscripts. Userscripts, once highly popular thanks to the rise of the Firefox web browser and the excellent Greasemonkey extension, are small scripts that modify certain elements on websites, or add elements to them.
Basic examples are scripts that change the color scheme on sites, that add links to YouTube videos on news sites, or remove annoyances from sites.
Tampermonkey for Microsoft Edge works fine already for the most part. You can visit sites like Greasyfork to browser scripts, and hit the install button to add them to Edge after installing the browser extension.
The installation dialog is a bit problematic, as you end up on a white page after hitting install. There is no feedback currently that the selected script was installed, but if you check the script management page, you will notice that it was installed despite the lack of feedback.
Most features work while some are not implemented yet. This means that some scripts won't work in Microsoft Edge currently, but that is only a temporary thing until the author of Tampermonkey for Microsoft Edge adds those to the extension.
The Tampermonkey interface is identical to that on Google Chrome. You may manage scripts, modify installed scripts, create scripts from batch, and modify preferences on top of that.
Scripts that I tried during tests worked just fine. Each script that is enabled is highlighted when you click on the Tampermonkey icon in Microsoft Edge. You may toggle its status directly from there which is handy.
First extensions support, now userscript support. Microsoft Edge benefits from these implementations as they increase the browser's attractiveness. However, since all major browsers support this, it is more of a catching up thing than something that makes Edge stick out of the crowd.
The availability of Tampermonkey for Edge, and thus userscript support, is nevertheless another important step in reaching maturity.
Now You: Would you give Edge a shot if it supported all extensions/scripts that you use?
