Webcam not working on mozilla firefox
Hi all, I have this problem: my webcam (is an USB camera on a desktop with Windows 10 - Innoo Tech 1080HD - quite a low budget one) does not work on the first on Firefox (using Google meet or any webcam test site), but after I run a FPS test on (https://it.webcamtests.com/fps) it will star working. I already have given the necessary permission for using the camera (checked both on windows and mozilla options) to all sites. Here is the thing: when I start a call in Google meet it says "camera is starting" but nothing appear on the screen. The camera does not work also in all sites for testing the webcam, nothing appear in the screen. But here is the trick: if I run the FPS test on webcamtests.com all start working, but if I close firefox on the next time I will open it, the camera will not start working again. All the times I run the FPS test the camera starts working properly.
How could I solve seriously this problem? thanks Lorenzo
