Been trying to reslove a issue i've noticed since updating to the latest firefox version that was released this week. Never had a problem before. Chrome and Edge load and play stream normally. Updated all the normal things like drivers for audio and video card, reinstalled Firefox with a new profile, no add ons etc, turned hardware acceleration on and off, still get the same issue. System is overpowered so its not down to it running slow or being old and also intenet connection is fine and I'm cabled in before anyone asks the "Have you turned it on and off questions :)" Going to try and downgrade to the version before and see it fixes the issue and hope its resloved in the next hotfix. It should be noted that this problem is related to streams and not normal videos, however someone on this forum posted problems with lagging videos, so maybe related.
