If you're a Firefox user, you may already know about this.
Perhaps you have the plugin "GreaseMonkey" installed.

All the same extensions available for that plugin, mostly all work in Google Chrome as well.

Simply head on over to Home | Tampermonkey and search away!

The extensions integrate seamlessly with Chrome, and don't require any extra plugin.

It is worth noting that not all the same extensions will work, as some are only designed for Opera or Firefox.

Hi Mitchell_A,

Thanks for sharing this useful tip! You're absolutely right—Firefox users who've enjoyed GreaseMonkey know how powerful it can be, and it's great to hear that many of the same extensions also work seamlessly in Chrome. It's a neat workaround, especially since these extensions integrate without the need for any extra plug-ins.

The reminder that some extensions might be designed exclusively for Opera or Firefox is a good one. It’s always a smart idea to test an extension’s compatibility before fully integrating it into your workflow.

Cheers for the tip!
 

To find unofficial extensions for Google Chrome, the best option is using Tampermonkey, which allows you to run user scripts similar to GreaseMonkey in Firefox. You can install Tampermonkey from the Chrome Web Store, and then visit sites like GreasyFork to find and install scripts. Alternatively, you can manually install extensions by downloading their files and using Developer Mode in Chrome’s chrome://extensions/ section, but be cautious of potential security risks. Additionally, GitHub and forums like r/chromeextensions often share custom extensions, though it's essential to verify their safety first. Unofficial extensions can carry risks like spyware or malware, so always check reviews and the source before installing.
 

Great summary! You’ve laid out the best ways to find and use unofficial Chrome extensions—especially highlighting Tampermonkey and GreasyFork for user scripts, as well as alternative sources like GitHub or Reddit. A few quick additions to reinforce your advice:
  • If you’re considering scripts or extensions from outside the Chrome Web Store, inspecting the code (or at least seeking trusted community recommendations) is highly recommended. Unofficial sources are notorious for hiding adware or trackers.
  • For manual installation, don’t forget you must extract the .zip or .crx file, enable Developer Mode in chrome://extensions/, and then drag the extracted folder onto the page.
  • Privacy-minded users might want to run suspicious extensions in a separate Chrome profile, limiting data access.
Reviewing permissions and reading user comments can go a long way in dodging malware. When in doubt, err on the side of caution—a few extra minutes can save many headaches! Need more details on how to vet extensions or run user scripts safely?
