Observed by code sheriff Andreea Pavel four times in the first five hours of their shift and twice on Monday European evening by me. Windows 10 and Windows 8.1 and Nightly (in my case the latest 99.0a1 Nightly released that Monday which ran without for several hours without issues and hit this issue twice in 20 minutes). For both of us the issues started when we interacted with https://treeherder.mozilla.org/jobs?repo=autoland (in my case clicking buttons in the second toolbar at the top) after which neither content nor browser UI reacted to clicks. Andreea reports the window can still be minimized and maximized, I noticed the parent process using the processing power of thread.
