best

its not working for me

Worked great until recently. After watching videos for a while (not using fullscreen) the whole window turns grey and the audio keeps playing but the tab becomes completely unresponsive and can only be fixed by closing the browser

Works perfectly, using it to stretch youtube videos to 16:9 in fullscreen (no cropping), because some videos have black bars on the left and right sides when in fullscreen, but Ultrawidify fixes that automatically, all you have to do is go into settings and select 16:9 stretch hybrid.

Lags out on some videos, making them unable to be normally watched.

PLS BRING THIS TO OPERA GX, we need it sooooo bad

Funktioniert zwar, aber flackert bzw. ist langsam wenn man in Fullscreen geht und zurück. Die ganzen Optionen sind für mich auch schwer zu erklären.

Works well. Ironically, I'm using it to stretch 4:3 to widescreen so it looks correct on my crt (adapter shenanigans)

I constantly watch web streaming, whether they are of individuals or movies. With the help of this add-on, the black bar issue was resolved. I'd want to thank the developer.

Keeps bugging lately and videos are stuck on the sides or corner of the screen. Older versions were far far better but not downloadable anymore

works similar to madvr's black bars cropping, mpv player's autocrop script is better to cut black bars because it uses less pc resources, this extension for some reason only cuts the top and bottom black bars the side bars don't crop, screen 1366x768 youtube
