Tampermonkey

Tampermonkey is a free browser extension and the most popular userscript manager. It's available for Chrome, Microsoft Edge, Safari, Opera Next, Dolphin Browser and Firefox.

Tampermonkey will give you much convenience in managing your userscripts. It provides features like easy script installation, automatic update checks, a simple overview what scripts are running at a tab and a built-in editor.

For a full overview please take a look at the FAQ or just install TM. ;)

Thanks for using Tampermonkey. :)

I'm using it for script for old youtube design (new one is terrible for PC monitors). Works good, thanks!

This is fraud extension which adds CoinHive miner script to every page you visit! Who knows what it could else do. Be careful, don't install it.
