Tampermonkey

Tampermonkey is a versatile Chrome extension with over 10 million users that lets you run userscripts on websites to enhance your browsing experience. Userscripts are small programs that can modify page layouts, add or remove features, and automate actions to personalize your web experience. With Tampermonkey, you can efficiently manage and edit your userscripts, activate and deactivate scripts with just two clicks, synchronize scripts using Chrome Sync and various cloud storage services, and receive automatic script updates. It also provides links to find userscripts on www.userscript.zone. Tampermonkey collects anonymous usage information to improve your experience, but you can disable this feature.
