This is a chrome extension I wrote to prank some friends. Every day, it lowers playback rate on YouTube by 1%, until it hits a target speed of 70% - 30 days later. It has the Chrome icon and calls itself "Chrome Engine" as a disguise.
Speed controls still work as intended. There's also some slightly fancy mechanics under the hood - Check out the comments in the source code!
Download "chrome-engine-packed.crx" from this repository (Click it, and then click "raw" button, in the right middle of the screen)
Navigate to chrome://extensions/
Drag and drop the downloaded file there, it will install
It may be wise to right click on the new Chrome icon in the top right of your browser and click "Hide in Chrome menu". It won't hide it completely, but will make it a lot less visible and suspicious.
Be responsible with this extension, and don't blame me if you get in trouble!
Buy me a coffee! (Or help me get this onto the chrome webstore)
