Due to https://github.com/netblue30/firejail/commit/5d88ee8957dc38a52c36f71b91c786dbec9d4ec9 we should provide an override option here IMO.

And sort the paths on allow-gjs.inc.
$ pacman -Q js78
js78 78.6.0-1
$ pacman -Qlq js78 | grep -v /usr/include/
/usr/
/usr/bin/
/usr/bin/js78
/usr/bin/js78-config
/usr/lib/
/usr/lib/libmozjs-78.so
/usr/lib/pkgconfig/
/usr/lib/pkgconfig/mozjs-78.pc
This appears to be the only counterpart path missing when looking at the
current lib64 entries with:
$ grep -Fnr lib64 etc

uim is a multilingual input method framework, so any program that takes user input potentially needs it to work.

The paths are taken from ssh(1) and sshd(8).
$ pacman -Q openssh
openssh 8.4p1-2
These are only used by sshd(8), so always blacklist them:
* ~/.rhosts: controls remote access to the local machine
* ~/.shosts: same as above
* ~/.ssh/authorized_keys: same as above
* ~/.ssh/authorized_keys2: same as above
* ~/.ssh/environment: potentially allows arbitrary command execution on
the local machine
* ~/.ssh/rc: allows arbitrary command execution on the local machine
* /etc/hosts.equiv: system-wide equivalent of ~/.rhosts
Note: There are files in /etc/ssh that are equivalent to some of the
above ones, but they are already blocked by `blacklist /etc/ssh/*`.
Note2: From sshd(8):
> If the file ~/.ssh/rc exists, sh(1) runs it after reading the
> environment files but before starting the user's shell or command.
So even if the user shell is set to /usr/bin/firejail and
disable-common.inc is loaded, this patch shouldn't interfere with sshd.
This file is actually used by ssh(1), so just mark it read-only:
* ~/.ssh/config: allows arbitrary command execution on the remote
machine (with e.g.: RemoteCommand) and also defines the connection
strength
Since version 7.3p1 (released on 2016-08-01), openssh supports including
other config files on ssh_config(5)[1][2]. This is the conventional
path for storing them[3], so mark it read-only:
* ~/.ssh/config.d: same as above
P.S. See also the explanation on the commit b5542fc94
("disable-common.inc: read-only access to ~/.ssh/authorized_keys"),
which last touched/added the "Remote access" section.

Leaving it limited to only ssh, ssh-agent and seahorse by default seems
unnecessarily restrictive.
From ssh(1):
> The most convenient way to use public key or certificate
> authentication may be with an authentication agent. See ssh-agent(1)
> and (optionally) the AddKeysToAgent directive in ssh_config(5) for
> more information.
$ pacman -Q openssh
openssh 8.4p1-2
With ssh-agent(1) running in the background (and with the private key(s)
loaded through ssh-add(1)), ssh(1) doesn't need direct access to the
actual key pair(s), so you could probably get away with this on
allow-ssh.local:
ignore noblacklist ${HOME}/.ssh
noblacklist ${HOME}/.ssh/config
noblacklist ${HOME}/.ssh/config.d
noblacklist ${HOME}/.ssh/known_hosts
And then this on the profiles of ssh key pair managers, such as
seahorse.local:
noblacklist ${HOME}/.ssh

This is the system-wide equivalent of ~/.ssh/config.
$ pacman -Q openssh
openssh 8.4p1-2
Reasons for blacklisting both /etc/ssh and /etc/ssh/* on
disable-common.inc:
Leave /etc/ssh that way so that profiles without allow-ssh.inc remain
unable to see inside of /etc/ssh. And blacklist /etc/ssh/* so that
profiles with allow-ssh.inc are able to access only nonblacklisted files
inside of /etc/ssh.

And move the scattered `noblacklist ${HOME}/.ssh` entries into it.
Command used to find the relevant files:
$ grep -Fnr 'noblacklist ${HOME}/.ssh' etc
Also, add it to profile.template, as reminded by @rusty-snake at
https://github.com/netblue30/firejail/pull/3885#pullrequestreview-567527031

That was added on the commit e93fbf3bd ("disable ssh-agent sockets in
disable-programs.inc").
Currently, it's the only ssh-related entry on disable-programs.inc.
Further, it seems that all the other socket blacklists live on
disable-common.inc. Also, even though this socket does not necessarily
allow arbitrary command execution on the local machine (like some paths
on disable-common.inc do), it could still do so for remote systems.
Put it above the "top secret" section, like the terminal sockets are
above the terminal server section.

* refactor google-earth{-pro} blacklisting
* fix google-earth-pro.profile
I've included all binaries found in the Arch Linux AUR package to private-bin. But I also added a note on ignoring private-bin because I'm not sure what google-earth is doing on other distro's.
* unbreak google-earth.profile
Not sure why we need grep, ls and sed in private-bin exactly but keeping them around wouldn't hurt too much I guess.

/bin/sh is usually just a symlink to bash. However this is not the case
for every distro, debian for example uses dash. bash,dash and sh have a
blacklist command in disable-shell.inc. An own allow-*.inc for it
enusres usage of all necessary nolacklists.
For private-bin sh is enough because it follows symlinks.
