Force YouTube to use Flash player over the HTML5 player

Download

Install Compare

The "YouTube use Flash Player" browser extension allows users to force YouTube to use the Flash player rather than the default HTML5 player. This can improve performance on low-end devices where Flash performs better. The extension only requests Flash on YouTube's website itself, keeping embedded YouTube players on other sites to use HTML5 for lightweight operation. Users can watch embedded videos in Flash by opening them in a new tab. To activate the extension, simply refresh any open YouTube tabs after installation. This tool is part of a suite of YouTube utilities designed to enhance user experience, including options such as YouTube HD, no annotations, no autoplay, and ad blockers. Note that the FAQs for the extension use Google Analytics with linked terms for user privacy.

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 use Flash Player requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
