What is Tampermonkey?
Tampermonkey (often called "Grease Monkey") is a powerful browser extension that allows users to install and run user scripts written by the community. These scripts can modify a webpage's appearance, add new functionality, or automate certain tasks, greatly enhancing your browsing experience.
Installing the Tampermonkey Extension
Ensure you have a stable internet connection. Follow these steps:
1. Visit the Chrome Web Store
Open your Chrome browser and go to the official Tampermonkey extension page.
2. Add to Chrome
On the extension page, click the "Add to Chrome" button, then click "Add extension" in the confirmation dialog.
Note: If you cannot access the Chrome Web Store, you can manually install Tampermonkey by downloading the .crx file from its official website. However, installation via the official store is the safer, recommended method.
Finding and Installing User Scripts
Once Tampermonkey is installed, its icon will appear in your browser toolbar. You can now install scripts.
1. Visit a Script Repository
Recommended user script communities include:
- Greasy Fork: https://greasyfork.org/ (multi-language support)
- OpenUserJS: https://openuserjs.org/
2. Install a Script
- Browse or search for a script you need (e.g., "video downloader," "ad blocker," "page beautifier") on Greasy Fork or similar sites.
- Click to open the script's details page.
- Click the green "Install this script" button.
- Tampermonkey will open an installation dialog showing the script's code, required permissions, and update info. Review this and click "Install."
Managing Your Scripts
After installation, you can manage and enable your scripts.
1. Enable/Disable Scripts
Click the Tampermonkey icon in your browser toolbar to open the management panel. Use the toggle switch next to each script to quickly enable or disable it.
2. Advanced Management
Click "Dashboard" in the management panel or right-click the Tampermonkey icon and select "Dashboard" to access detailed settings. Here you can:
- View and edit script source code.
- Set script run rules (e.g., which websites it works on).
- Check for updates or manually update scripts.
- Export/backup your script configuration.
Security Best Practices
Important: User scripts have broad permissions to modify webpages. Always:
- Install scripts only from trusted communities like Greasy Fork or OpenUserJS.
- Check a script's rating, last update date, and user comments before installing.
- Regularly update your scripts to get feature improvements and security fixes.
- For unfamiliar scripts, set them to "Manual enable" in the Dashboard and activate only when needed.
Common Issues & Advanced Tips
Script not working after installation?
Check: 1) If the script is enabled; 2) If the script's "match rules" include the URL of the current website; 3) Try refreshing the page or restarting the browser.
How to write your own script?
Tampermonkey provides a powerful script editor. Click "Create a new script" in the Dashboard to start. Writing scripts requires some JavaScript and web knowledge. You can start by modifying existing simple scripts.
By following these steps, you should have Tampermonkey installed and be ready to use user scripts. It's like giving your browser a Swiss Army knife—go explore the possibilities!
