Camera freeze extensions, explained
People searching for a “camera freeze extension” are usually looking for the simplest thing that will hold a still frame on a call. An extension is a reasonable guess, and for Google Meet it can work. For Zoom, Teams and Discord it cannot, and the reason is worth thirty seconds of your time.
The short answer
A browser extension can only reach video inside that browser. A virtual camera registers with the operating system, so every app can select it. If any of your calls happen in a desktop app, you want a virtual camera.
Where each approach actually works
| Call happens in | Browser extension | Virtual camera |
|---|---|---|
| Google Meet (browser) | Works | Works |
| Zoom desktop app | No | Works |
| Microsoft Teams desktop app | No | Works, after a one-time setup step |
| Discord desktop app | No | Works |
| FaceTime, Webex, OBS, Slack huddles | No | Works |
Why an extension cannot reach Zoom
A Chrome extension runs inside Chrome. It can intercept the browser API that a web page uses to request your camera, which is why it can change what a site like Google Meet receives. The Zoom desktop app never touches that API — it asks the operating system for the camera directly, and the browser is not involved at any point.
A virtual camera solves the problem one level down. It presents itself to macOS as a camera device, so any app that can list your webcam can list it too. One install covers the browser and every desktop app at once.
What FreezingCam is
FreezingCam is a virtual camera for macOS, not a browser extension. You pick it as your camera in whichever app you are calling from, then freeze the frame, loop a short recording of yourself, or fake a bad connection from the menu bar.
It is macOS-only today. If you are on Windows, OBS Studio's Virtual Camera is the free equivalent, and you can join the Windows waiting list to hear when our build is ready.
