I am using the latest version of FF, which is 21.0. I have went through each and every plugin and extension and removed anything unnecessary. Also ensured that everything is up to date. As part of my testing, I had also disabled every single extension as a test.

Here is the issue. When I open certain threads (or other sites), I get an error at the top of my screen that an addition plugin is needed to display media. Here is the error:



Of course I then click on the option to find the plugin, and I get a message returned 'that no suitable plugin' could be found. It's not a huge problem, as everything works and I can't find a single thing that doesn't load when this happens.

But if anyone else is using the latest FF, and Windows 7 home premium, here is one of the pages that displays the error for me:
