Where did you download from? The main page at

https://get.adobe.com/flashplayer/

usually has two optional offers from Intel/McAfee, not from Norton.

Anyway, your Firefox reported to the forum that you already have Flash installed, so perhaps the issue is one of the following:

• Site doesn't have permission to use the Flash plugin (check for a dark gray icon similar to a small Lego block toward the left end of the toolbar to manage plugin permissions).
• Site needs a plugin other than Flash such as Java or Unity -- can you give a link to the page so a volunteer can investigate?

I have been using Google Chrome earlier and all the gaming sites worked perfectly! Recently installed firefox from better privacy but I can't play any of the games online.

I particularly like playing Ben 10 Ultimate Alien Games but everytime the game loads completely and just a white screen appears.

I read on a forum to upgrade my Adobe flash player but that too didn't help. Is there any plugin or extension? I am using the latest firefox.

Please help me.. Thanks.

Hi russmartinez, does Flash work in your Firefox on Adobe's test page:

Please be aware of the need to give sites permission to use Flash: Why do I have to click to activate plugins?
