How to Manage Camera Permissions in Firefox

Allow, block or reset camera access for websites in Firefox, check the operating-system camera permission, and fix the most common camera access problems.

Firefox decides camera access for each website. A site can use your webcam only after you allow it, and you can change that decision later from the address bar or from the browser settings. If the operating system blocks Firefox from the camera, no site permission will help, so this guide covers both layers.

Before you start

  • Use the desktop version of Firefox. Menu names can differ slightly between versions; older releases on Windows call the settings page Options instead of Settings.
  • Make sure the camera is connected and not in use by another app. Video call apps and camera utilities can hold the device and stop the browser from opening it.
  • Open the site over a secure connection. Firefox offers camera access only to secure pages, so a page loaded without HTTPS will not show a camera prompt.
  • Know where the video goes. Permission management happens locally in Firefox, but once you allow a site, what happens to the video depends on that site or service. Check its privacy information rather than assuming the stream stays on your device.

Step-by-step instructions

Respond to the camera prompt

When a page asks for your camera, Firefox shows a prompt below the address bar. If you have more than one camera, check which device is listed and pick the one you want before you allow access. The prompt has a Remember this decision option: tick it to keep your choice for the site, or leave it unticked to grant access for the current visit only. Choose Allow to share the camera or Block to refuse.

Change permission for the current site

  • Open the site whose camera access you want to change.
  • Click the permissions icon at the left end of the address bar, next to the padlock.
  • Find the camera entry. Click the X next to it to clear the saved decision, so the site asks again next time.
  • Reload the page and answer the prompt again.

You can also open Page Info for the site, go to the Permissions tab and find Use the Camera. Turn off Use Default, then choose Always Ask, Allow or Block. Ticking Use Default again returns the site to your global setting, which keeps the change easy to reverse.

Manage all camera permissions in browser settings

  • Open the Firefox menu and choose Settings.
  • Select Privacy & Security and scroll to the Permissions section.
  • Next to Camera, click Settings to see every site with a saved camera permission.
  • Change the status for a site to Allow or Block, or select it and use Remove Website. Remove All Websites clears the whole list.
  • To stop all new sites from asking, tick Block new requests asking to access your camera. Sites already allowed in the list keep their access.
  • Click Save Changes.

Allow Firefox in the operating system

If Firefox itself cannot reach the camera, the operating-system permissions need attention. On Windows 10 and 11, open Settings, go to Privacy & security, then Camera, and make sure camera access is on and desktop apps are allowed to use the camera. On macOS, open System Settings, go to Privacy & Security, then Camera, and turn on Firefox. Restart Firefox after changing these settings. On Linux, sandboxed packages such as Snap or Flatpak can have their own device permissions; check the permissions for the Firefox package if the camera is detected by other apps but not by the browser.

Check the output

Open a webcam test page or the call or image tool you plan to use, and allow access when asked. While the camera is active, Firefox shows a camera sharing icon in the address bar and a sharing indicator. If the preview shows video from the expected device, the permission chain works.

Picture quality is a separate question from permission. Firefox has no setting for webcam resolution or frame rate; the site requests them and the camera and driver decide what is actually delivered. If the image looks soft or choppy, check the camera and quality options inside the site, and improve the lighting, since a dim room often makes cameras lower the frame rate and add noise.

Common problems and next steps

  • No prompt appears: the site may be blocked in the camera permissions list, or new requests may be blocked globally. Remove the site from the list or untick the blocking option, then reload.
  • The wrong camera opens: clear the saved camera permission for the site and choose the right device in the prompt, or select the camera in the site's own device settings.
  • The camera is detected but shows a black image or an error: close other apps that may be using it, check any privacy shutter or hardware switch, and confirm the operating-system permission for Firefox.
  • The permission was allowed but the site still fails: reload the page, restart Firefox, and test the camera in another app to see whether the problem is the browser or the device.
  • You want to revoke access after a call: clear the camera permission from the address bar or remove the site in browser settings.

If the camera works in other apps and other browsers but not in Firefox after these checks, try a fresh Firefox profile or the browser's troubleshooting options to rule out a setting or extension that interferes with camera access.
