I have verified this issue and it is still reproducible with the latest Firefox Reality version 9-40341450 (ade4895) build on websites like Instagram, Twitch and Twitter.
The issue is no longer reproducible on YouTube and Vimeo. It is also not reproducible on other websites like The Internet Archive or Facebook.
This behavior can be observed on the Oculus Go (Android 7.1.2), HTC Vive Focus Plus (Android 7.1.2) and HTC Vive Focus (Android 7.1.2) devices, but not on the Oculus Quest (Android 7.1.1).
