What is Ultrawidify?
Ultrawidify is a Firefox add-on that greatly improves video viewing on ultra and super-wide displays. Capable of auto-detecting and fixing aspect ratios for a smoother viewing experience, it supports a wide range of video platforms from Youtube to Twitch, Vimeo to Streamable, and more. In cases where auto-detection isn't possible due to site restrictions, this handy tool provides manual adjustment options. Further features include video alignment, player detection override and stretch video capabilities for improved versatility.

Summary
Analyze keywords

Need to remove unnecessary black bars from this youtube video you're watching? Ultrawidify is here for you. It should work on Youtube, Netflix, Twitch, Vimeo, Streamable (and on embedded videos that are hosted on these sites). It may work elsewhere as well, but no guarantees.

Important note: This addon is only tested and intended to work with Google Chrome specifically. If you're using a different browser, you're on your own. No, Edge is not Google Chrome (and neither is any other chromium-based browser).

FEATURES

1. AUTOMATIC ASPECT RATIO DETECTION Ensures that video will be cropped without you having to lift a finger. It even re-adjusts crop if aspect ratio changes mid-video. Autodetection is not 100% accurate and has some limitations, but it's accurate enough for most cases.

Autodetection is not supported on all sites. Some sites (e.g. Netflix, Disney+, Hulu) use DRM in order to prevent video piracy, and such protection measures interfere with automatic aspect ratio detection.

2. MANUAL ASPECT RATIO CORRECTION

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!
