Works great on with FF119 on my 34" 3440*1440. Just select the mode you want, refresh the browser and you're good to go.

Add-on doesn't work, clicking the icon does nothing, and trying the keyboard shortcuts do nothing on several attempts with different Netflix movies. Tried restarting Firefox as well as restarting my PC.

Edit: another app was messing with this one's ability to do it's job. Amending review.

WOW Finally I can enjoy my Big screen
thank you it works Amazing
Peace

Awesome extension.

Działa jak należy, poprawiając niedoróbkę leniwych informatyków netflixa.

simple and easy

Thanks to the creator! It works perfectly.

great ext...

Works GREATR with my 35" 3440x1440

Does what it says and removes the black bars from top and bottom for ultrawide viewing in fullscreen mode. Kind of a shame that this isn't a native feature for Netflix.

Funciona perfectamente y es fácil de usar. Recomendado probar los distintos modos que trae.

10/10.

Works great and couldn't be more simple to use ! Well done ! Thanks

amazing, works as expected.
