Never seen this one before:

"[Error] SecurityError: Attempt to use history.replaceState() more than 100 times per 10 seconds"

I had a near-instant crash too, but different kind. Firefox iOS. The vibes are leaking

		On iOS, all browsers use WKWebView behind the scenes as required by Apple. So crash behavior is similar to Safari.
