Developer Stephen Downward is devilishly genius: Discover a YouTube prank you can make on friends and foes with an insidious Chrome extension.
The harmless Chrome extension name slows down YouTube video playback by 1 percent every day until it reaches 70 percent of the original video speed.
Install the extension on a friend or partner's computer and watch them pull their hair as they try to figure out what's going on with their videos.
The extension will work on many more computers if the prank victim has synchronized the Chrome they use on multiple devices with the same account. Note that even changing the playback speed with the YouTube controls will not help, because the extension will immediately compensate for any change the user chooses.
If you are tough enough and want to try a prank on a friend's computer, visit the repository of the developer on GitHub from the victim's computer, and click the “chrome-engine-packed.crx.” link. Then download the extension by clicking on the "Raw" link.
Then go to "chrome: // extensions" and you'll see your browser extensions management page.
Drag the .CRX file you downloaded to this page and click 'Install'.
Once installed, a Chrome logo will appear alongside the extension "button" next to the address bar. You can if you want to hide it by selecting it with one right click on the menu.
Then you have to wait. Hold on until hell begins for your boyfriend.
We wish you good luck and we ask you not to torture your victims too much.
