Great and lovely app! however I find myself getting a bit frustrated with the app defaulting to fit screen mode all the time, even something as simple and going out of full-screen and back in for a second will make it cropped in again and I have to press the button again and. Not sure about ultra-wide monitors but my laptop is 16:10 and the sides being cropped really messes up text-heavy videos.

If a feature is added that saves your last click i.e fit-screen-mode=0 will make every video not be cropped in persistently until you click the button again (and goes =1) then every video you watch will now be cropped in, this extension will get 5 stars!

Now im not wasting any monitor space!
It works well, ty!

Does nothing.

This extension, in its current version, makes writing any sign in comment section impossible .This means that until it is repaired, the expansion pack is of no use to me.
However i put ⭐⭐⭐⭐⭐ becouse i love to get video fit my 19x10 aspect ratio ❤️ Belive will fixed soon.

Thank you so much for providing a full-screen toggle button in the player for the mobile version of YouTube. Great job!

Прекрасно работает в браузере, на андроиде. Спасибо 🙏

This does absolutely nothing.

Hi dev, Microsoft Edge on Play Store (Android) now offers extensions, would be nice to try the extensions there.

1,000 stars. Wonderful. Many many thanks.

I wish it would widen the video instead of zooming in. (Try Ultrawidify, UltraWideo)

Most useful tool for YouTube mobile

I'd switched to using YouTube solely within FireFox on mobile to block ads without needing to deal with ReVanced. The main problem I had was that the YT player within FireFox was missing the 'zoom to fill' in full screen feature for widescreen videos that were uploaded in a standard 16:9 aspect ratio with black bars on the top/bottom on a modern phone with a widescreen aspect ratio when horizontal. This extension is a hidden gem and fixes that perfectly by adding a well designed button to the top left of the player when in full screen (give it a second to load sometimes). Uncheck the box in extension settings for automatic enable to have manual control so you can only turn it on when you need it, and you're golden. I hope this is maintained by the dev - this extension is a lifesaver for 'cinematic' wide aspect ratio content still often uploaded in 16:9 like music videos, movie/game trailers, or short films.

awesome! this one automatically works on android!

After Searching Tons of extensions finally, have something that works also for 21:10 aspect. Thank You for your work.

Nicely fixes fullscreen issues on mobile when viewing in "desktop mode", although the settings dialogue is not available, so I can't set the default to keep aspect ratio. Not a huge deal you just have to click the icon on each video to fit to screen correctly, otherwise a bit of the bottom is cut off.

Works great on mobile, works just like the app!!!

this fullscreen addon for youtube doesnt play yt videos once thier clicked on
