I would like to disable the webcam for firefox.

My notebook has a built in webcam with awful quality, not only I don't want people I interact with on firefox to know that I do have a webcam, whenever i join hangouts it automatically starts to broadcast my webcam which i find specially unsettling.

I already applied a piece of tape covering the lens but i want to block firefox from even finding out that i do have a webcam.

is this possible?

I don't want to disable my webcam completely tho, I use it to skype every day.

You can block it for specific sites:

  1. Write in address box about:permissions then Enter
  2. Select target site
  3. Use the camera: Block

Reference: Mozilla Support Forum: What are the camera and microphone permissions?

Firefox site permissions

Other way:

  1. Visit the target site
  2. Right click → View Page Info → Permissions tab
  3. Use the camera: Uncheck Use default then Choose Block

Reference: MozillaZine: About protocol links

Firefox site permissions 2

  • Thanks for such a good answer, what I really want tho, is to block Firefox from even knowing I have a webcam, it should be possible somehow – Computer's Guy Nov 28 '14 at 08:30

    @Dolan, I agree there should be a way, may be it does need building from source. I will give it a try. – user.dz Nov 29 '14 at 06:12
