downloaded, worked immediatley. That's all i wanted so 5 stars :)

Best ultrawide extension for Firefox I've found and I've tried many. Even works with local media servers like Jellyfin.

Vielen Dank für diese Extension! Schön, dass hier hier Ideen weiter gedacht werden als bei manchen Desktop-Website Entwicklern der jeweiligen Streamingplattformen.

super recomendo 😍😍😍😍😍😍

add fixed 16:9, 21:9 and 32:9 aspect ratio options for manual selection please!

does what it says, as of may 2021. it's a little too auto-magic for my tastes, but it saved movie night! so maybe it's better that it just works as easy as it does.

Installed on Firefox Nightly for Android to fix the problem of the bottom of Youtube videos being cut off in full-screen mode. Works perfectly for my 20:9 Samsung Galaxy A52 screen. It's incredible that Firefox doesn't include this add-on in its normal set of recommended Android add-ons, or simply fix this problem.

I use it in firefox nightly for android, so I can see youtube without cropping . 5 stars for the extension! Not so much for firefox.

thank you, needed this for crunchyroll

Really nice extension.. Works like a magic for new Firefox android

Works and has a gorgeous simple interface.

Funcionó fantástico en Firefox for Android Nightly. Ya no tengo problema al visualizar cualquier video.

UtraWimeo is the only one that actually works, I tried many other addons and wasted a lot of time for this. If this didn't work, I would need to be spending money for bigger monitor on computer I rarely use. Email answer was great also. This plugin is also private, nothing is sent out of computer.

Thanks, this fixed youtube cropped videos in fullscreen landscape mode

I'm using this with a 4:3 CRT and it's amazing. Works on HBO, Youtube, everything I've tried so far. Great for old 4:3 movies and videos that were uploaded with forced 16:9 pillarboxing, to put them back in fullscreen like they should be.
