I don't want websites to query/enumerate my list of addons. How do I hide addons from websites?
I want to keep my of addons, extensions and plugins private. They can have acceptable content-types, but I don't want content delivery contingent on having/not having elements installed.
I assume this would have to be a per-site configuration item, I would prefer to block all, accept some (like I have to do with flash/java).

Websites can only enumerate plugins, not extensions. Sites detect some extensions (like ad blockers) based on the page of missing/added elements in the page.
Here's an example of a page that enumerates plugins:
- Standard: http://www.jeffersonscher.com/res/plugins.html
- Secure: https://www.jeffersonscher.com/res/plugins.html
You can use an add-on to empty out the plugins array, although this might cause unpredictable results on sites where you actually do want to use plugins. For example, I posted a Greasemonkey userscript here: https://greasyfork.org/en/scripts/18256-hide-all-plugins
I didn't create a UI to easily add/exempt sites, but someone could do that, or perhaps you'll find something easier to use.

Hey, may I ask you a question?
I want to hide the add-on or plugins tap by changing the defaut configuration of "about:config". So I creat a pref.js file but I don't know which item in "about:config" is the relevant configuration, and could you tell me how i can do that?
Thanks a lot.

Hi tdassj, I see you have a separate question about this: https://support.mozilla.org/questions/1147720
I actually don't think there is a preference for hiding the about:addons page (or any other internal pages). If I think of anything, I'll post it in the other thread.

Thanks a lot @jscher2000
waiting for your further support :)
@jscher2000
And do you have any other methods to customize the requirement ?
