This script will:

• Add video controls.
• Remove 9gag video overlays in favour of native controls.
• Play video at 50% volume by default (configurable).
• Fix timebar-drag bug that makes 9gag go weird.

If you want videos to still start muted, edit the script and change the variable VOLUME_LEVEL to 0. If you want to change the default volume level, set it to any value from 0 to 100, being 100 the maximum volume. For example:

var VOUME_LEVEL = 100;

Known problems:

• If you don't interact with the webpage (just press F5 and don't click anywhere) but want videos to autoplay with audio, videos won't be able to autoplay. Is a browser security limitation to avoid those old noisy popups. Just click elsewhere and it will work as expected.
