Browser / Version: Firefox Mobile 134.0 Operating System: Android 15 Tested Another Browser: Yes Chrome

Problem type: Something else Description: Youtube videos switch to portrait orientation in full screen view. Steps to Reproduce: When i go to full screen mode by clicking the full screen icon, the video will correctly be shown in full screen in landscape orientation for about 10 seconds. but after that, the orientation automatically switches to portrait orientation whilst still in full screen view. this happens with all videos on YouTube. On other video sites this doesn't happen, so it seems to be a specific issue with YouTube.
