Hi there creater, thanks for this amazing addon.
Just a quick feedback, after the latest update on Youtube, the addon icon are not appear in the youtube bar, but the function still work using keyboard shortcut.

Edit: button is back.
Another question, is there anyway to keep the rotation while using picture-in-picture mode?

i am amazed how effortlessly it rotates

Edit 2021/04/24
tested with all other add-ons disabled on latest version of firefox. text selection works for all other add-ons, but stops working when only this add-on is enabled and all other add-ons disabled.

Edit 2: 5.2.2 did not fix the issue

Edit: the only fix is when i change the shortcuts in Manage extensions.

This works great, but I think the add-on breaks the navigation and highlighting features in the search bar. I can't use ctrl + shift + arrow keys to highlight text in the search bar anymore. It works when this add-on is disabled, and doesn't work when the add-on is enabled. Can you please address this with a patch fix?

I'VE WANTED TO BE ABLE TO ROTATE YOUTUBE VIDEOS FOR YEARS, NOW I CAN THANK YOU!

Since the last update, it can't be full screen with 90 ° rotation. My screen is vertical,I hope the next update can solve this problem.

Edit 2020-09-24:
Thank you. Now it works! I didn't know that there was a way to change the shortcuts for extensions. I assumed that it is not possible because there is no option to change Firefox' own shortcuts.

Hi. I really like this addon, but since I don't use a US keyboard, I can't get all of the keyboard shortcuts to work. The rotate and mirror shortcuts don't work. All others do (moving and zooming). Can you please look into that? I'm using a german qwertz keyboard.
Thanks and keep up the good work!

Possible solution: With some experimentation, I noticed the issue went away whenever I closed all tabs of YouTube, and opened up a new one (it wasn't enough to close all but one, I had to close all and then open a new one). The issue came back if I opened a second or more tabs. Hope this helps.

Edit 3: Started randomly working, here's hoping it stays that way.

Original review: Zoom / Mirror works fine but Rotate is not working for me for some reason.

Edit 1: Thanks for the response. I'm using Firefox Browser 80.0.1 (64-bit). I'm using the current default layout on YouTube. I couldn't get it to work on any videos so I don't know if a link is needed. I also tried disabling all other add-ons but the issue stayed, so it shouldn't be a compatibility issue with other add-ons affecting YouTube.

Edit 2: I tried reinstalling, didn't fix it. I'll edit the review again if the problem resolves or I figure something out. Thanks for responding either way, I appreciate it.

It needs a "remember rotation" so it gets perfect.
(Can you make it for Opera browser?)

Very useful.

To other users, if you are using a pivot monitor, you must switch to full screen and then use the rotate function to see the correct screen.

Super quick for learning K-pop dances or moving/rotating YouTube videos in general!

5/5. saved me from breaking my neck.

A shortcut for mirror would also be very appreciated to make watching dance practices easier

Hi. Very good extension. Could you do it for Chrome? Thank you

Edit: Works perfectly now, thanks for the quick update!

Rotating when watching a video works great, but the "rotate 90°" button on the videos tab (for thumbnails) does not appear, at least not on the new YouTube layout.

Thank you!
