Firefox Error: Camera permissions are not available in this browser

Is your feature request related to a problem? Please describe.
I managed to run the barcode-scanner on chromium-based browsers, is it planned to run the barcode-scanner also on firefox?
Describe the solution you'd like

Run the scanner on Firefox
Describe alternatives you've considered
I tried alternative solutions (my stack is vue/ionic/capacitor) with no luck:

• https://github.com/gruhn/vue-qrcode-reader
• https://github.com/bitpay/cordova-plugin-qrscanner

Additional context
I took the code from: https://github.com/capacitor-community/barcode-scanner#usage

The current browser solution is in beta and not ready for production, so it is possible that this implementation has issues. We are working on a better solution for the future, but this has currently not the highest priority since we are working on other issues at the moment. I will keep the issue open and inform you about some news.

I looked into it and it looks like that the error is generated by this call:

barcode-scanner/src/web.ts

Line 98 in 5a1e8d6

const permission = await window.navigator.permissions.query({

and is related to this: mozilla/standards-positions#19 (comment)
Basically Firefox is not implementing query for "camera".
After a quick research I found out that on firefox must use this to prompt for camera permission: https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia
on code should be something like that:

      const firefoxPermission = navigator.mediaDevices.getUserMedia({ video: true });

Is it possible to try a PR to fix this?

Just opened a PR for this. With this, firefox is also working. @pavva91
