Site permissions
Decide which sites may use your camera, microphone, location, notifications and devices, and change your mind later.
A site has to ask before it uses your camera, your microphone or anything else that could reveal something about you. Luma asks you, and remembers your answer if you want.
When a site asks
A panel opens from the address bar: “example.com wants to”, followed by what it wants. Click Allow or Block.
Remember this decision is ticked by default, so Luma won’t ask that site again. Untick it to answer for this time only. A site asking to open an external application is asked about every time.
| The site wants to | What it means |
|---|---|
| Use your camera / Use your microphone | Video and voice calls, recording. |
| Know your location | Maps, nearby shops, local weather. |
| Show notifications | Messages that appear in Windows even when the tab is in the background. |
| See text and images copied to the clipboard | Pasting from a button inside the page. |
| Use MIDI devices | Music keyboards and controllers. |
| Know when you’re actively using this device | Showing you as away in chat apps. |
| Connect to devices on your local network | Printers, routers, home devices. |
| Open an external application | Links that open another app, such as Zoom or Spotify. |
A few harmless features are allowed without asking, such as full screen, keeping the screen on during a video, or copying text to the clipboard. Requests for features Luma can’t offer a proper choice for yet are refused (see Not there yet).
Pop-ups
A pop-up window can open only right after you click something on the page. When Luma stops one, the address bar shows Pop-ups blocked: click Always allow if the site needs them.
Change a decision
- For the site you’re on: open the privacy panel from the shield. Permissions for this site lists what you decided.
- For every site: open the privacy dashboard, or click Privacy dashboard next to Site permissions in Settings › Privacy & security. Set each permission to Allow, Block or Ask.
- All at once: in Clear browsing data (Ctrl+Shift+Delete), tick Site permissions and exceptions.
Screen sharing and devices
When a site wants to share your screen, Luma shows what you can share under Screens and Windows. Pick one, tick Also share the computer’s sound if you want, and click Share. The site sees only what you picked, and only for this request.
Sites that work with USB, HID, serial or Bluetooth devices show a chooser too. Pick the device and click Connect (or Pair for Bluetooth). The site gets only the device you picked. A USB, HID or serial device stays available to that site until you quit Luma.
A tab that is using your camera or microphone is never put to sleep.
