Tested on a large number of different computers, there is one common problem.
360 video is very slow in the firefox browser. At the same time, it works great in other browsers (chrome, edge, even internet explorer). In firefox, it slows down even on very powerful PCs.
H264 or VP9 - it doesn't matter. It's about 4K (3840*1920).
Even 8K (7680*3840) plays perfectly in chrome, and even 3K (3072*1536) is very slow in firefox.
Is there any hope that the situation will improve?
