download windows media player browser plug in for firefox 56

It seems that as soon as I get most things squared away in a new Mozilla browser, then they have come out with three new versions, so when I'm still struggling with version FF5 (as I am now) there will be version 9 that I'm getting constant annoying 'reminders' to upgrade to. I'm tired of going through all the troublesome steps of upgrading and figuring out what Mozilla has changed and left out of a another browser upgrade and re-installing the plugins, extensions, add-ons and customizations and troubleshooting everything that doesn't work, as I am still doing now with Firefox 5. What is the solution? Upgrading again for the 3rd time in the last 2 months is not an option. I've already gone through all the Mozilla troubleshooting info and accessed the page on this topic and nothing works. So the question is, why is Firefox 5 requiring I install an older Windows Media Player plugin, version 1.0.0.8 from 2007 when I already have it installed?. it still doesn't show up in Firefox 5 nor will this browser play a WMV file in the embedded test player linked from the Mozilla WMP plugin troubleshooting page, nor from other pages that have WMV players embedded. I also tried the 'repair' option in the plugin installer. So I tried re-installing it with the original installer and the installer that is available from the URL above (they appear to be the same except my original installer has a 2010 date).

In spite of already having the required plugin installed and showing in my Programs and Features panel, this WMP plugin is not showing up on my Firefox 5 plugins panel. When I check my 'Programs and Features' panel in Windows 7 on my control panel, I can see that I already have something installed named, 'Windows Media Player Firefox Plugin' installed and it is dated, and it is version 1.0.0.8.

Then there is a 'Manual Install' button, and when I click that, it takes me to a third party plugin site called ' ' that has a Firefox WMP plugin available that is dated April 2007. If I then click to install the Windows Media Player 11 plugin, it goes to another Firefox panel that says, 'No plugins were installed, Windows Media Player 11 - Not Available'. When I click 'Click here to download plugin' in Firefox 5, I get a Firefox panel that says I need Windows Media Player 11, but I already have Windows Media Player 12 and the Firefox WMP browser plugin installed on this computer. When I click on a link to play a standard WMV video in Firefox 5, in the movie player window it says 'Click here to download plugin'.
