Firefox android won't play a video image

Hi, I'm trying to play a 360 video I think it uses html5 and webgl. '''In the desktop version it works perfectly''', with the mouse I direct the camera and I have image and sound. However''' in the android version I only have sound, the image stays black.''' I connected the phone with remote debug and this is what I got: [https://pastebin.com/0BPYgfjg Debug file Mozilla5 Android 13 Mobile rv109 Gecko Firefox114] To play it, I go to the website [https://omegaodin.itch.io/00000 https://omegaodin.itch.io/00000] I click on "run game" and again on the little play button. Playback starts, there is audio but no picture. In others mobile browsers as Samsung browser or Chrome, it's working. I am very novice, but I would like to know the cause and if there is a technical solution that the developer can apply. Thank you very much for your help.
