I think every infinite loop should be instantly stopped. Like javascript:while(1){history.go(-1);}

Reproducible: Always

This is almost definitely WONTFIX, just as far as implementation goes. There isn't guaranteed to be a relevant Web history for every place that JavaScript runs (e.g., outside of a browser in XUL), and the actual application may not even have a such thing as a browser. Even if that weren't the case, people do write legitimate loops where the condition is true or 1, and use conditionals inside the loop body to break out of it, especially if the conditions are complex.

this doesn't belong here and I don't think it's something we should be putting in core:js either.

running while(true) { something(); } will eventually popup the slow script dialog.
