Flash plugin works well on Chrome, but why it does not work on Firefox? :(


I've updated Flash Player quite a number of times, but whenever I try to play a video on Youtube or any other websites, the same line of words appears asking me to download Flash Player. I've got the Adobe Flash Player installed not long ago and it works just well on Chrome. The flash plugin in Internet Explorer is not working too..

please help ~

Google Chrome comes with its own version of the Flash Player plugin.

Your system details list doesn't show that the Shockwave Flash plugin is installed and enabled.

You can find the latest Flash player versions for Firefox on this page.
