📝 Browser Permissions: Camera, Microphone and Location

Browser permissions decide which parts of your computer a website may reach. Camera, microphone, location, notifications and clipboard access are the main ones. They default to off and are requested per site — but once granted, they usually stay granted.

Permissions are per site

Camera access granted to one site does not transfer to another. That is good design, with one side effect: your permission list accumulates. Dozens of sites you visited years ago may still be sitting in it.

Clicking the icon to the left of the address bar shows what the current site holds, and lets you revoke it in one click.

How sensitive is each one?

• Camera and microphone: the most sensitive. Grant only to sites you use for calls and trust.
• Location: reasonable for weather and maps, unnecessary for a news site.
• Notifications: the most abused permission by some distance. Most sites want it to push advertising.
• Clipboard: can read what you copied. Treat with care.
• Automatic downloads: do not grant multiple-file download rights to sites you do not trust.

What to check when a prompt appears

Ask two questions: which site is asking, and why now? There is no legitimate reason for a news site to want your camera. If the request does not match what you are doing, decline it.

Note that choosing “block” means the browser will never ask again. If you later need that permission, you have to enable it by hand — which is precisely why so many people believe their camera has broken.

Confirm permissions are working

Before a meeting, the fastest way to verify camera and microphone permissions is to test them. The webcam test and the microphone test show both the permission state and whether the device itself responds.

You can review your browser’s broader security posture with the browser security test, which lists which protections are currently enabled in one place.

Make it a routine

Every six months, open your permission list and clear out sites you no longer use. Pay particular attention to notifications — it is the list that grows fastest, and clearing it noticeably reduces the junk you see during the day.

Frequently asked questions

Can a site I allowed turn the camera on without me knowing?
When the camera is in use the browser shows an indicator in the tab and the address bar, and most computers also light a hardware LED.

Are permissions different in private browsing?
Yes. Permissions granted in a private window are discarded when it closes.

Will revoking a permission break the site?
No. The site will simply ask again when it next needs that feature.
