User reviews

Ultrawidify was praised for effectively stretching videos to fit ultrawide monitors and enhancing viewing on platforms like YouTube and Plex. However, recent updates have caused significant problems: a persistent in-player UI cannot be disabled; videos sometimes shrink unpredictably; settings fail to save; and keyboard shortcuts become unreliable. Users report performance issues such as freezes and high memory usage, along with compatibility problems on certain sites and browsers. Despite much appreciation for its original simplicity and effectiveness, many users urge the developer to revert changes to restore previous stability and functionality.

Pros

Effectively removes black bars on ultrawide monitors by stretching videos automatically to fit the screen.
Works well on various video platforms like YouTube and Plex before recent updates.
Previously simple and lightweight, providing seamless automatic video stretching without issues.
Highly appreciated by users with ultrawide screens for enhancing viewing experience.
Developer recognized for putting significant effort into the extension.

Cons

Latest updates introduced a persistent, intrusive UI overlay that cannot be disabled and annoys users.
Post-update versions frequently fail to save user settings or reset them unexpectedly.
Videos randomly shrink to small rectangles or have flickering issues, disrupting viewing.
Keyboard shortcuts and auto-scaling features no longer function reliably or as before.
Extension causes performance issues, including browser freezes, high memory consumption, and compatibility problems with platforms like Netflix and Vivaldi browser.

Seems to work, but the UI is so annoying and completely unable to be disabled. I disabled in settings, modified .json files and imported them, changed dev settings, but nothing.

Imprescindible si tiene una pantalla ultra ancha, simplemente es obligatorio tenerlo ya que se va aprovechar de esos videos en formato 16:9 que tiene franjas para adaptarlo a tu pantalla ultra ancha de manera automática. Explicación: Estas viendo un video en YouTube en el formato normal de toda la vida(16:9) pero de pronto el video pone franjas negras en la parte superior e inferior, cuando pasa eso la extensión recorta esas partes negras y acomoda el video de tal forma que aprovecha todo el ancho de tu pantalla, y lo hace de manera automática y mientras se reproduce el video en vivo, y si durante la reproduccion del video se quitan nueva mente esas franjas negras entonces vuelve al formato original(16:9) para no perder nada de imagen. El que creo esto realmente se las cráneo para dar con la solución definitiva a las barras negras en videos 100/10.

darei volentieri le 5 stelle se il menu non sparisse a caso! fino a ieri il menu appariva nel video ma ora non lo fa pie per farlo funzionare sono obbligato a fare schermo intero e non per vedere il menu e pregare chissà quale divinità finta in modo che io possa dire a questa estensione di eseguire lo stretch per favore risolvete

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Ultrawidify requires a few sensitive permissions. Exercise caution before installing.
