Plug-ins not working Win10 32-bit
When I go to about:addons and look at my plug-in list they're there but when I go to check for updates it give me the error "No plugins were found. If you believe this is an error, please file a bug and let us know. "
Windows 10.0.10240 32-bit Home Firefox 40.0.2

Can my test page detect your plugins:

There is a preference you can use to hide plugins from sites that use collections to enumerate them. To see whether that setting has been customized:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.
(2) In the search box above the list, type or paste enum and pause while the list is filtered
(3) If the plugins.enumerable_names preference is bolded and "user set" to anything other than its default value of * (meaning "all") then that would explain why sites that check the plugins collection do not see any plugins not listed in that preference value.

Your website did not detect any plugins. After I may have voided my Firefox warranty, I saw that plugins.enumerable_names was user set and had the value of nothing. I'll set that to * and see what happens.
It worked! I don't know how that got changed, and I don't know much about the things in about:config so I definitely would not have solved this on my own.
That preference is a bit of a secret. You would generally only learn about it if you were researching something called browser fingerprinting, a technique some sites use to recognize your browser based on the sum total of its technical characteristics.
