Fix Browser Webcam and Microphone Permissions Denied

Problem overview

Web applications like Google Meet or Discord run in your browser but cannot access your microphone or camera. The browser displays an error indicating that permissions were denied, preventing your video and audio from transmitting.

Common causes

• Accidental click on “Block” when prompted by the site
• Operating system privacy settings restricting the browser
• Antivirus software blocking webcam access
• Another application holding exclusive control of the camera

Solution 1: Check browser site permissions

1. Navigate to the web application you are trying to use.
2. Click the padlock icon (or site information icon) on the left side of the URL bar.
3. Look for the Camera and Microphone toggles or dropdowns.
4. Ensure both are set to Allow.
5. Refresh the webpage to apply the new permissions.

Solution 2: Clear site permissions and re-grant

1. Open your browser settings and search for Site Settings (Chrome/Edge) or Privacy & Security (Firefox).
2. Locate the specific website in the list of recent permissions.
3. Click the trash can icon or Reset permissions to clear saved rules.
4. Return to the web application and trigger an action that requires the camera.
5. Click Allow when the permission prompt appears at the top of the browser.

Solution 3: Check Windows Privacy settings

1. Press Win + I to open Windows Settings.
2. Navigate to Privacy & security > Camera.
3. Toggle on Camera access and Let apps access your camera.
4. Scroll down and verify Let desktop apps access your camera is enabled, ensuring your browser is listed below it.
5. Repeat these steps under Privacy & security > Microphone.

Solution 4: Close apps with exclusive access

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Look for applications like Zoom, Microsoft Teams, or OBS Studio that might be using the camera in the background.
3. Right-click these applications and select End task.
4. Restart your browser and test the camera again.
