This is so far the best extension for my ultrawide video consumption at 3440x1440p. No other can force crop or aspect ratio in such an easy way. I would recommend the icon of this app (which appears at the tools bar once installed) sharing that same icon when searching it on the add-ons bay of extensions. Cheers from Spain.

Works and makes videos look a lot better on a 34" 21:9 Monitor using the full screen

Funcționează, dar trebuie setat manual ce opțiune vrei. Pentru mine a funcționat „Force crop”, pentru un monitor de 21:9.

I'm not mad just giving my review.
I can't get this app to work on Firefox nightly for andriod on my 20:9 andriod phone and the phone is a samsung galaxy a53 5g and my phone is the only I am using this app for my phone do to the fact that it is 20:9. I have a samsung galaxy tab s5e and a windows 11 hp pavilion laptop.

works for me 👌

Очень хорошее дополнение.Спасибо

Great extension. works exactly like it should.
Even in Plex! :)
But i have 1 issue. the shortcut (CTRL + ALT + C) doesn't cycle through the experimental modes, which is the one i need for the video to run properly in 21:9. i have to manually click in the menu, which sucks a bit :/

(an option to choose which ones it cycles through would be nice....
"normal", "experimental", "both" )

Anyways, apart from that, it works perfectly.
Thank you.

Ne fonctionne pas, ne fait strictement rien et les options qui fonctionne empire le format...

While the options menu would benefit from clarification, "Force crop" mode was exactly what I was looking for — cropping the black bars from the top of some Vimeo videos. Now they fill the whole ultrawide monitor, not just half of it with the black bars everywhere.

Does not work, waste of time

This extension is so useful !
I have a 21/9 screen and when videos are uploaded in 16/9 with black bands at top and at the bottom, in fullscreen there are contours, the extension can remove them !
