    Majority of the users reporting on the internet that redesign of YouTube is five times slower on Edge and Firefox browser, as compared to Chrome browser.

    Now you might be wondering why YouTube is working perfectly on Chrome? Your answer would be, it is a robust web browser, right? Of course not. It is happening because Google designed YouTube in a way so that it runs faster on Chrome as compared to Edge and Firefox. We all know that YouTube and Chrome both belong to Google.

    Seriously I was not expecting this from Google. To force users to download Chrome browser, they used this cheap approach.
