2024-11-23 vandim 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
2024-11-09 Tiger II 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.
2024-09-06 wando Lags out on some videos, making them unable to be normally watched.

2024-04-26 Firefox user 18389140 Fixed my twitch and youtube, saved my marriage, cured my stomach ache and drove my kids to lacrosse practice every day. Not a single add on does that, but if you believe in yourself and in Tamius, it is possible. Dont let your memes be dreams!

2023-11-28 Firefox user 14302851 Funktioniert zwar, aber flackert bzw. ist langsam wenn man in Fullscreen geht und zurück. Die ganzen Optionen sind für mich auch schwer zu erklären.
2023-11-27 Braix Works well. Ironically, I'm using it to stretch 4:3 to widescreen so it looks correct on my crt (adapter shenanigans)
