Hey guys, I have been having issues with flash player and java lately. It seems as though the browser is not recognizing the add-on and extensions. I have installed the latest flash/java versions, tried safe mode, reinstall firefox, and nothing seems to work. I have windows 10 v1511. My last solution was to check other browsers to see if flash and java was enabled on theirs. It seems Internet Explorer and Google Chrome both have flash player and java working. Only Firefox was not working. Any help would be appreciated. Thanks

Make sure your Java (Not JavaScript) is up to date Verify Java and Find Out-of-Date Versions {web link}

Version 8 Update 73 Release Date February 5, 2016 http://java.com/en/download/manual.jsp


If you have problems with current Shockwave Flash plugin versions then check this:

  • see if there are updates for your graphics drivers

  • disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)

Wow! Thanks for the help FredMcD! It turns out it was the hardware acceleration problem. All the other solutions didn't fix the problem until i disabled hardware acceleration! I'm not sure what causes this but it fixed the problem! Thanks so much for the help, I was pulling my hair out trying to fix this problem ever since I got my new laptop. THANKS!
