When trying to open or preview an AR Scavenger H5P activity under Firefox, the following error message is obtained : "Impossible d'accéder à la caméra. The request is not allowed by the user agent or the platform in the current context." (preview mode)  or "Permission denied" (view mode). It prevents any use of the activity, even if access to camera is allowed for the whole website. No browser prompt to authorize camera access is displayed.

On the other browsers, this does not look to be the case.

Current H5P Lib version is 1.4.1. Same results were obtained with the official example of the activity on h5p.org.
