Flash® Player for YouTube™
Because of important changes on YouTube™ this extension may not work as expected, and due to very limited free time its development has ended. For info, Adobe will stop updating and distributing the Flash® Player at the end of 2020.
The HTML5 player is the default player on YouTube™ for Edge, Chrome, Firefox, Opera, Safari, and other modern browsers. Unfortunately for hundreds of thousands people the HTML5 player is laggy and/or consumes much more material resources (CPU, RAM) than Flash® Player. What is really frustrating for these people is that YouTube™ has removed the possibility to choose between both players, forcing them to watch videos with it, loading the Flash® Player only when a problem occurs with the HTML5 player. Fortunately, browser extensions exist! Just like my popular Firefox add-on YouTube™ Flash® Player, Flash® Player for YouTube™ can force the use of the Flash® Player on YouTube™ (see How to use Flash® Player for YouTube™). Flash® Player is directly integrated with Chrome, and updates are automatically included in Chrome system updates, so Chrome users don't need to worry about security. You can verify that it is installed by typing chrome://settings/content/flash in the address bar. The HTML5 player has been greatly improved over the last years, but based on what people say about Flash® Player for YouTube™ it is still not working perfectly on all devices, so if like a lot of people you are experiencing issues with it, or if you just want to compare both players, you should give a try to Flash® Player for YouTube™ because if your PC or laptop doesn't easily support HTML5 videos there are good chances that it will improve your watching experience without having to buy a new computer with better hardware components. To install Flash® Player for YouTube™, click the button below then click on the "Add To Chrome" button. You can remove it at anytime from the extensions page chrome://extensions if the HTML5 player is not as bad as you thought.
