Play Videos/Songs faster or slower in one click in Chrome (No Extensions)

drift.js

javascript:(function () {var speed = Number(prompt("Insert the desired Speed")); if (speed !== NaN) document.getElementsByTagName("video")[0].playbackRate = speed})();

drive.js

javascript:(function () {document.getElementsByTagName("video")[0].playbackRate = 1;})();

YOUTUBE.md

How To

Chrome has an amazing feature that allows you excecute a JS funciton as one of your bookmarks. Someday, when I was watching an YouTube video and wanted to play faster than 2x (podcast video related), I can't. So I created those two scripts and passed them as bookmarks saving in my bookmarks bar.

Now, whenever I want to play a video faster than 2x, I can and I can pick speed or return to normal speed.

Disclaimer: Use it with moderation. I just go for 3x or 4x speed.

Steps

1. Ask for create a bookmark (cmd+D in Mac)
2. If you don't see an URL input, click on More..., paste the code from drift.js into URL and give it a name
3. (optional) If you want to have a button to set to normal speed again, repeat the steps and create with the drive.js content
