Well there goes my short-lived interest...\n\nAlso you've claimed before that no JavaScript JIT means W^X would be possible but this is not true. The SpiderMonkey in UXP has supported W^X from the very beginning despite it using JIT; Firefox's did it from version 46 (before UXP's fork point), and only disabled it by default on all platforms in version 116 (except OpenBSD where W^X is mandatory) because they saw the performance trade-off not being worth it (probably because their support for W^X is designed for a single-process model in the first place, but it looks like the alternate method which would be designed for multiple proce introduces overhead across all processes too anyway).\n\n* * *",
