Mozilla does not have phone support. Many private companies offer support for Firefox and other browsers, but those are not officially licensed or approved by Mozilla.

Is this problem on your Galaxy S4 or on a PC (Windows? Mac?), or both?

There are many possible reasons. Does it only affect one website?

Do you get a page that has a section called Technical Details, or can you find an error code in parentheses that describes the problem more specifically?

Or can you give a link to it (assuming no login is required)?

I am unable to get you a link to it. Its only on pogo.com a game called hearts. It's a card game. It also says a java needs to be updated. And when I updated it it would not accept it because it says the update for Java is the most current. And when I try to verify Java it says this plugin is not supported.

Okay, I'm going to assume this problem is on Windows and not Android.

Could you check the Add-ons page to see whether Java is listed and, if so, whether it is blocked? Either:

  • Ctrl+Shift+a
  • "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Plugins. On the right side, you may find two different Java plugins, the key one is called

Java(TM) Platform SE 8 U51 version 11.51.2.16

Do you have that version, or an earlier version such as U45?
