This add-on plugin for Firefox is perfect for those who love
j-pop and k-pop in particular because a lot of fans will upload
their videos in portrait mode but 90 degrees so you would have to
flip your monitor (or head) 90 degrees to enjoy it. Likewise,
mirror mode is perfect for dance practice and there's even zoom
functions as well.
From this:
To this:
The Firefox plugin is called "Rotate Youtube Video (+ Zoom
/ Mirror)"
You can get it here: https://addons.mozilla.org/en-US/firefox/addon/rotate-youtube-video/
Download and install it then refresh the Youtube video that
you're on if you're watching anything and the button will appear
ont he video. Keep in mind that the rotate button acts differently
than if you press on the "Zoom/Mirror" text.
But what if you prefer using Google Chrome?
You can download "Rotate that video clip" which can be found
here
Please keep in mind that it is the best chrome plugin I could
find and isn't as good as the one on Firefox. I only recommend
Brave browser which is Firefox but without the privacy nightmare of
Edge, Chrome or Firefox. If you do value your privacy get
https://brave.com/Brave or
at least use Firefox, never Chrome or Edge.
Huzzah! No more neck pain!
