There was three identical files in three different locations, so I renamed all except the one with the latest date (*.dll.old) and it worked like a charm. Thanks.

</p><p>In the plugins-section, I had two versions of the shockwave flash player - 12.0 and 11.3 - and I only wanted 12.0. When I disabled the older version, the newer was also disabled.
</p><p>I tried uninstalling flash player, and then re-install it, but the two different plugins were still there.
</p><p>Then I went to about:plugins, and found the folder where the old shockwave plugin were - something like this:
</p>
<ul><li> path: <strong>C:\Windows\SysWOW64\Macromed\Flash\</strong>NPSWF32_12_0_0_70.dll
</li></ul>
<p>I discovered two flashplayerplugin.exe-files in that folder - both the new and the old. I then uninstalled again, and updated the folder; only the new .exe-file was removed. Then I deleted the folder (called flash), and re-installed flash player, and voila, problem solved. Now I only have the newest flash player.
</p><p>And when you're at it, check the programfiles-folder and delete that too after uninstalling, so that there is no more old files lurking around.
</p><p>Hope this helps!&nbsp;:)

For one thing, the previous answer was only repeating the question.&nbsp;;)
But mainly, your second paragraph, which does address the question, may not actually be desireable. I found from other sites that I could simply:
</p><pre>go into my programs, and/or my Windows system folder and delete the

<p>npdeployjava1.dll file.
</p><p>I did this, and it worked perfectly!&nbsp;:)
Hope this helps!

This has recently started to pile up in my Add-Ons/ Plug-in container as well and is a bit annoying. Well, for those who like to be tidy&nbsp;:)
</p><p>The solution previously offered on here, to delete registry keys, does NOT work for duplicate plug-ins with different versions. I have not tried yet, to remove the registry key and then re-install, to see whether the latest version only will appear in the plug-in list.
</p><p>The other example is my Java Deployment Kit. No duplicate older version, but it *constantly* shows 'Ask to Activate' and to be careful with the extension, although it's the same version as the Java Platform plug-in. Luckily, FF offers to remember the 'Allow' for each site, so it's not that big of a bother. The only thing I noticed is too many 'unresponsive' scripts on web pages, but have no idea these events are connected.
</p><p>So, if we are communicating now better (hopefully with the attached pictures), why is FF doing this, and is it something that developers can look into. That's what I like to know.
</p><p>Thanks guys.
</p>Short answer, Extensions and Themes are installed in Firefox, while Plugins are not.

</p>You have never been able to delete plugins from the "Firefox/Tools > Add-ons > Plugins" page.

You can only do that with extensions that you have installed yourself (globally installed extensions can only be disabled).

I know it use to be you could delete a plug in or add-on directly from the add on page. But my Add ons Page only has "always activate" or "Never Activate". Nothing about Deleting. In my searching so far I've found nothing about this. So I'm still needing assistance. Many thanks.
