You’ll encounter this error when Google Chrome or Edge runs out of memory. This is often because of an app or website that uses excessive memory. This phenomenon occurs in Chrome and Edge and not in Firefox.

This means the memory stack limit set by Firefox is different from that of Chrome and Edge.
