Offensive popup telling me I need media player update update but is not compatible with my Mac OS 10, then, how can I block this popup?

I downloaded the update, but the installer says that it won't work with my operating system. It appears constantly and it is very annoying. How can I stop it? Block popup is selected in my preferences.

Unfortunately, at a given time that you have installed the extension MediaPlayer, possibly as part of a free download of something else.

Please remove this one and disable all non-essential or unrecognized extensions on page modules. Either:

  • CMD + SHIFT + a
  • "3-bar" menu button (or tools) > Add-ons

In the left column, click Extensions. Then take a critical look on the list on the side right and, in case of doubt, disable (or delete). Keep in mind that all extensions are optional and none is included with Firefox when you get it first.

Often, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.

What is fix?
