      In Firefox, we see perf issues on some sites when the stack size is too big. https://bugzilla.mozilla.org/show_bug.cgi?id=1578350 …

      Sites that depend on, or junk being pulled in because of ads/trackers/other unwanted crap?

      Also, let me guess, they hang because these are native calls thanks to JIT hell, whereas with a reasonable interpreter control would return to browser after a fixed number of interpreter steps...

          Personally, I'm of the opinion that is a bug in the website and that Firefox shouldn't fix it. Firefox is working as intended and they need to either stop trying to break devtools or find a better way to disable it.
