How to Allow Camera Access in Firefox for a Makeup Mirror

Open the mirror page in Firefox and click Allow when Firefox asks for camera access. If you already blocked it, click the padlock in the address bar, open connection or site permissions, and change camera access for the site to Allow. If the page still cannot start the camera, check that the site is opened over HTTPS, close other apps that may be using the webcam, and review your computer's camera privacy settings.

Start with the Firefox prompt

The quickest fix is the first permission box Firefox shows when the page asks for camera access. Open makeupmirroronline.com, wait for the prompt near the address bar, choose the camera you want if Firefox lists more than one, then click Allow. If you have a built-in laptop camera and a USB webcam, pick the one you want before allowing access. If no prompt appears, Firefox may already have a saved block or allow rule for the site. That is common after an earlier test.

Open the page and wait a moment for the request box.
Pick the correct camera if Firefox shows a device list.
Click Allow, not Block.
Reload the page if the prompt appeared before the camera was plugged in.

Change a blocked permission for this site

If you clicked Block earlier, you do not need to clear all Firefox data. Change only the camera rule for this website. In Firefox, click the padlock icon beside the web address. From there, open the site permission details and look for the camera setting. Remove the block or switch the site to Allow, then reload the page. This mirror does not ask for microphone access, so you only need to fix the camera permission.

Click the padlock at the left of the address bar.
Open the permission details for the current site.
Find Camera and remove the blocked rule or set it to Allow.
Refresh the tab and try again.

If Firefox still will not start the webcam

A browser permission is only one part of camera access. Firefox also needs a secure page context for camera use. That usually means the page must load over HTTPS. The mirror also depends on the camera not being locked by another app such as Zoom, Teams, or the Windows Camera app. On Windows, system privacy settings can also block desktop apps from using the camera. If Firefox keeps failing after you allowed the site, check Windows camera privacy and confirm camera access for desktop apps is turned on. Some people expect saved access to work with no internet on the first visit. That is not a safe assumption here. Offline app files can work only after a successful earlier visit, and camera behavior without a connection varies by browser.

Confirm the page address begins with https://.
Close other apps that may be using the webcam.
On Windows, review camera privacy settings for desktop apps.
Do not count on first-time offline use.

Using the mirror once permission is fixed

After Firefox starts the camera, the page works like a simple makeup mirror. The front view is mirrored. You can switch to another webcam if Firefox and your device make more than one available. The 1x to 3x zoom is a digital crop, not optical zoom, so image sharpness can drop as you zoom in. For low light, the site uses a bright white border on the page as a screen light. It cannot change your hardware brightness from the web. You can freeze the image right away or with a 0, 3, 5, or 10 second timer. There is also a movable and resizable reference pin and an optional grid. If you save an image, export is started by you and the file is a PNG. Where that PNG ends up depends on your browser and operating system download or file picker settings.

Space freezes or resumes the image.
P pins or unpins the reference overlay.
Escape stops the camera.
Shortcuts do not fire while a text field is active.

Open makeupmirroronline.com in Firefox over HTTPS.
Click Allow on the Firefox camera prompt and pick the webcam you want.
If blocked before, change the site camera rule from the padlock menu, then reload.
If it still fails, close other camera apps and check Windows or system camera privacy settings.

Why does Firefox not show the camera prompt anymore?

Firefox may already have a saved decision for the site. Click the padlock in the address bar, review site permissions, clear the blocked rule or change camera access to Allow, then reload the page.

Can the mirror brighten my laptop screen for makeup use?

The page can show a white border as a screen light, but it cannot change hardware brightness controls from the web.

Where is my saved mirror photo?

The image is exported as a PNG after you start the save action. The exact save location depends on your browser, operating system, and download or file picker settings.
