% sysctl -d kern.elf32.allow_wx kern.elf32.allow_wx: Allow pages to be mapped simultaneously writable and executable % sysctl -d kern.elf64.allow_wx kern.elf64.allow_wx: Allow pages to be mapped simultaneously writable and executable % <https://lists.freebsd.org/archives/freebsd-questions/2023-July/003962.html> Well, instead of allowing `WX' globally, I'm now only setting it on firefox:
$ sudo elfctl -e +wxneeded /usr/local/lib/firefox/firefox \
/usr/local/lib/firefox/firefox-bin
It works just as well--as a workaround for the time being.

Created attachment 243659 [details] Error messages from firefox-116.0,2 After the recent firefox-116.0.2 update, _all_ tabs crash when these are set in /boot/loader.conf: ``` kern.elf32.allow_wx=0 kern.elf64.allow_wx=0 ``` The same result with a clean firefox package reinstall (and also a brand new run with ~/.cache and ~/.mozilla removed). A ~150 MB core file is left behind after this. Didn't have any issues with any of the previous upgrades at all. I've worked around this by setting both those sysctl vars. to `1'. The error message from a pristine first-run of Firefox is attached.
