Both Intel and Arm still does not allow to use addresses beyond 48 bit even if formally the address word is 64-bit. Which means that SpiderMonkey (JS engine in Forefox) even on 64 bit can use NaN boxing technique, https://searchfox.org/firefox-main/source/js/public/Value... . However when future processors start to support bigger address space, like 52 bits or even more, the SpiderMonkey will need to be redesigned.

I think that once the memory usage of your browser starts approaching those numbers even Chrome and Firefox would start looking for memory leaks...
