This happens to me sometimes in Opera, Chrome and Firefox, and it's extremely irritating. I remember the good old days when dual-core processors were just starting to become mainstream, and browsers would just use one core. The browser could crash all it liked, but the system would always be responsive. But now browsers take advantage of all cores, meaning that if they crash, they can block your entire system. I wish there was a way of telling the browser to strictly use only K cores on Windows. I'd instantly switch to a browser offering that feature.
