First it didn't work at all. Then I checked a link the dev posted as reaction to a 4-star-review and added "--disable-direct-composition-video-overlays" to firefox-command in terminal (using Linux). Works like a charm now. Thanks!

Edit: stopped working again after switching to another tab. hmm...
Edit2: Figured it out, it only works in actual fullscreen, not F11. Then even without the added line. Dumb me ^^

flawless, works instantly after page refresh! rad!

This doesn't work at all on Hulu sadly, needs an update for the latest firefox version and testing with multiple streaming platforms as well.

UPDATE: It works! Just had to refresh webpage after installation.

Good job!

Real easy to use, works like a charm. Weird that Disney doesn't fix this themselves.

Thanks Dev, works great.

Works as expected and solves the annoying fact that Dinsey+ doesn't support ultrawide monitors.

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.
