YouTube Flash Video Player

YouTube Flash Video Player is a powerful tool that will let you choose Flash video player as default YouTube video player.

YouTube Flash Video Player is a robust Chrome extension that allows users to select the Flash video player as the default for watching YouTube videos. Unlike the standard HTML5 player, the Flash player often provides access to higher resolution and HD streaming options, enhancing your viewing experience.

This extension supports MultiProcess Firefox Electrolysis and offers easy toggling between Flash and HTML5 players via its settings. Though unofficial and unaffiliated with YouTube™ or Adobe®, it is designed to improve playback quality for YouTube™ users seeking superior video resolution.

    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.

    YouTube Flash Video Player requires a lot of sensitive permissions. Exercise caution before installing.

    Risk likelihood
    Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

    YouTube Flash Video Player has earned a fairly good reputation and likely can be trusted.
