Mozilla addressed a YouTube playback problem that was affecting certain Firefox users, specifically with high-resolution videos. After months of investigation, the issue was traced back to an incorrect VP9 muxed byte stream served by YouTube, which was not a regression on Firefox’s part. This led to videos playing fine in some instances but stopping abruptly in others due to buffering issues. While this is not the first time Firefox users have faced problems with YouTube, it underscores the challenges of using non-Chromium browsers with certain services. Mozilla plans to release a fix in Firefox 127.0.2 to resolve the issue later this month. This highlights the ongoing struggle for Firefox users in a digital landscape dominated by mega-corporations like Google.
