Firefox native messaging regression in 0.9.62.4 -> 0.9.64rc1

[cinnaboot]

When upgrading to firejail 0.9.64rc1, the firefox extension https://github.com/woodruffw/ff2mpv breaks.
It makes use of https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Native_messaging to talk to other native applications.

In firefox.local, I have
# Python 3
noblacklist ${PATH}/python3*
noblacklist /usr/include/python3*
noblacklist /usr/lib/python3*
noblacklist /usr/lib64/python3*
noblacklist /usr/local/lib/python3*
noblacklist /usr/share/python3*

After upgrading to 1.9.64rc1 (and in 1.9.64), I get the following in strace:
[pid 261] execve("/home/user/.mozilla/ff2mpv.py", ["/home/user/.mozilla/ff2mpv.py", "/home/user/.mozilla/native-mes"..., "[email protected]"], 0x7f9a121b4c00 /* 86 vars */) = -1 EACCES (Permission denied)

firejail --noprofile does work too

Do I need to add some more options for the new DBus filtering maybe?

Forgot to add, this is on Arch Linux

Add ignore noexec ${HOME} to your firefox.local.

In 0.9.62 was ignore noexec ${HOME} by default set even it shouldn't.

Thanks, that helped.
I ended up needing to add a bunch of stuff from mpv.profile to make it go also:

ignore noexec ${HOME}

# copy firejail config parts from mpv.profile
noblacklist ${HOME}/.config/mpv
noblacklist ${HOME}/.config/youtube-dl
noblacklist ${HOME}/.netrc

include allow-lua.inc
include allow-python3.inc
mkdir ${HOME}/.config/mpv
mkdir ${HOME}/.config/youtube-dl
mkfile ${HOME}/.netrc
whitelist ${HOME}/.config/mpv
whitelist ${HOME}/.config/youtube-dl
whitelist ${HOME}/.netrc
whitelist /usr/share/lua
whitelist /usr/share/lua*
whitelist /usr/share/vulkan
