My Logitech c920 webcam doesn't show video in Firefox, but the audio works fine.

I've tried it with all add-ons disabled.

It's the only webcam on my system.

被選擇的解決方法

I found a fix for the problem. For Firefox, in its about:config controls under the media.*.enabled preferences search the media.autoplay.enabled was set to false. Returning it to its default boolean value (true) resolved the problem. A response from this thread also suggested changing any media.*.enabled preferences back to their default settings, but it didn't apply to my solution. Therefore, other media.*.enabled preferences may not be relevant.
