Useful, but subtitles don't show when in use (I use it to watch diney+)

I’ve noticed an issue when using UltraWideo with Apple TV+ in the Firefox browser. When I stretch the video to fill my screen, the Apple TV+ subtitles no longer display correctly. They get cut off or covered up, making them unreadable. This didn't used to happen, I believe. I suspect the extension is applying the stretch only to the

Works great for the most part. Only problem I have is that it makes Plex fail to change the video (next/previous, changing a stream etc.) when in fullscreen mode.

Would be befeter if the quality of the video was not so affected.

Does what it is written, but it just suddenly stopped working after the new FF update.

Edit: Thanks for the response, Dev. I am using Windows 11 21H2, FF 99.0.1 (64bit) I tried clean uninstall and reinstalling firefox, didnt work.

I wish it had hybrid upscale too.

Like upscaling the video to 18:9 and then stretching the result to fill up the whole screen. Right now stretch mode is hardly used.
The extension 'UltraWidify' does have this option though, but this extension is way more stable and performs a LOT smoother so I would like to see it here.

Works great and I enjoyed it for months when I had a UltraWide but when I upgraded to a Samsung G9 that has a wider aspect it no longer works correctly. It would be really nice if you added support for other resolutions. Right now the only options I have are to not use the add-on, have a ridiculous stretch that is unwatchable, or have it cut inches off the top and bottom of the video. I just want it to fill the screen and leave the sides black so the Video is as large as possible on my screen without cutting anything off. Your screenshots show that I should use "Normal Mode" for this effect but that's not how your addon works, not even with a standard Ultrawide.

The extension is great but I would love to see support for just removing the letterboxing seen on disney +. I don't want it upscale, just zoomed in enough to remove the letterboxing present.

It appears to not work when you fiddle with it, then when you fullscreen the video it works, so it took me a bit to figure that out. (on Disney+ at least)

My Oneplus 6T developed a problem after getting an update. If I'm not using YouTube then all videos are cropped in to take up the whole screen, chopping off content. This happened for whatever browser I was using, including Chrome. Getting Firefox and this add-on solved that. I guess the only thing I could ask for is being able to pinch or unpinch to change the modes (normal/upscale/stretch) or something like that. That way I don't have to open the menu to change it if I ever want to.

Edit: for those of you unable to use this, check out F-Droid and Fennec. F-Droid is an open source Android repository (think of it as a 3rd party app store for free/open source apps. Fennec is a free and open-source version of Firefox, and using Fennec you can download the specific older version of Firefox(Fennec) that allowed non recommended add-ons like this. I believe it was version 68.12.0

Amazing work! Allows me to use my old widescreen tv with vga pc resolutions.
My one issue is the resolution doesn't change in twitch.tv theater mode, only on full screen.
Thanks dvlden, you rock! :)
edit: You're right! I'm use to the wide aspect in theater mode since originally writing the review. This addon is the best!

works great but i wish you could add this feature it will make it 10 times better, can you make an option for half and half ? i mean upscale/stretch hybrid, this will minimize the crop and the picture wont look too stretched. idk if its possible but if it is that would look much better,best regards

It's a very good add-on with all the modes I needed and keyboard shortcuts to turn on and off. Works very well for the most part.

But there is a small problem. In youtube when I stop/pause the extension with the keyboard shortcut (ctrl+shift+9), leave full screen, then change video or refresh and then enter full screen again, I cannot unpause the extension. I have to leave full screen press the unpause keyboard shortcut and then it works again.
