How do you hide installed plugins in Firefox?

This website shows that too much about you can be seen: http://centralops.net/asp/co/BrowserMirror.vbs.asp

Most plugins don't need to be seen by content providers.

There isn't a way to do this yet in firefox. This is necessary so that the server you are connecting to can know what form to send the content back to you in. The closest analogy I can draw is how SSL sends all of the acceptable connection types (SSL1, TSL, etc.) and the server can pick what it wants to use to communicate. When we are sending all this information to the server we are letting it know that we have these plugins and it can send us content we will be able to use.

Yet? Is it being planned? I realize the point, but again, most plugins don't need to be seen. For example, the Foxit Reader plugin. Foxit is an alternative for viewing .PDF documents. Nobody needs to know what I'm using to view .PDF files. I disabled the plugin, and when I opened the next .PDF Firefox asked me what to do, I said "remember," and it uses Foxit without people knowing. But some plugins you need, and the other end doesn't need to know the details. – Carl May 1 '10 at 15:02
I don't know of any plans to add this functionality. Overall it isn't to much of a concern. Ther are so many bigger attacks which can be levied against a browser for disclosure of information such as the CSS visited link attack which can find out your browsing history, and a number of others. This really is relatively minor and is necessary for the way the web works. I really wouldn't be that concerned about it. If you are I suggest using a proxy server (CGIirc like) – Daisetsu May 1 '10 at 17:26
I found the above centralops site wouldn't tell me what Firefox was running until I allowed it in NoScript. – Umber Ferrule Aug 2 '10 at 22:50
