A suspected YouTube interface bug spikes RAM usage above 7 gigabytes, users report severe lag and frozen tabs — bug might be trapping browsers in an endless lay

That forces the browser to continuously recompute layout geometry, redraw interface elements, and update rendering states, rapidly consuming CPU resources and memory. A user shared screenshots on Reddit showing CPU cores pinned near maximum utilization while YouTube tabs became nearly unresponsive. Others reported browser-wide slowdowns severe enough to temporarily freeze entire systems.

Mozilla developers are reportedly still investigating the issue, though no broadly confirmed fix appears to exist yet. The fact that both Firefox-based and Chromium-based browsers appear to experience similar problems further supports the suspicion that the issue may originate primarily with YouTube. For now, the exact root cause remains unofficial; neither Google nor YouTube has publicly confirmed the source of the problem.

Notton I've noticed youtube interface bugs with watchlater disappearing, but my firefox is only consuming 3.6~3.8GB memory after letting it play for 8hrs consecutively at 1.75x playback speed. Though I have noticed videos stuttering when opening Tom's top page and any news article. Reply

usertests Chat on YouTube live and previously live streams can be a major user of RAM and cause the tab to crash. Also spikes CPU usage. Not as bad as this bug though. Reply

chaos215bar2 Sounds like a browser bug first, and perhaps a YouTube bug second. Why is a single tab allowed to keep consuming memory to the point it freezes entirely? Reply

DingusDog Probably another instance of trash AI code. Reply
