Firejail: electron-mail won't work with firejail unless I specify --no-profile

Doesn't work: firejail electron-mail including variants of adding --seccomp and --netfilter
Works: firejail --noprofile --netfilter=/etc/firejail/nolocal.net electron-mail Doesn't work when --seccomp is added

I need some help knowing which variables are causing it to not run as running the commands in the terminal doesn't give me any logs to find out the problem.

What I also tried is copying /etc/firejail/electron.profile to become /etc/firejail/electron-mail.profile but no luck. Though, maybe I can start from electron.profile and it'll work by just removing some stuff?

Would really appreciate any help!

@MystesofEternity Creating the electron-mail.profile automatically closed this issue. Feel free to re-open whenever you notice something missing or otherwise not working. Also, when your OS updates firejail, make sure to remove your ~/.config/firejail/electron-mail.profile file, as it will clash with the one in /etc/firejail. Thanks for reporting this here!

I've put together a testing profile for electron-mail. Can you create ${HOME}/.config/firejail/electron-mail.profile with the below content and post your findings here please? If we can get this to work properly I'll add it to git master as a new profile with firecfg support etcetera. But let's see what this does for you first.

On my Arch machine it works, although I don't have a protonmail account and didn't bother to create one. Also, to tighten the profile I made it a whitelist one and included private-dev. The latter will output some harmless error messages, don't mind these for now. Here's my output:

$ firejail electron-mail

Hey there, thanks for giving me something to test with!
So here's what happened:

Error: cannot access profile file: whitelist-usr-share-common.inc

I checked my /etc/firejail directory and indeed, whitelist-usr-share-common.inc doesn't exist
I am using firejail-0.9.68-1 and I am running fedora 30
Could you give me the contents of your whitelist-usr-share-common.inc? I'll create it and see how it goes

A thing to note though:
I commented apparmor because I am using fedora and there is no apparmor there RIP

Could you give me the contents of your whitelist-usr-share-common.inc? I'll create it and see how it goes

That won't work, as whitelist-usr-share-common.inc functionality isn't available in your firejail version. Just comment that line, like you did with the apparmor option.

I need some help knowing which variables are causing it to not run as running the commands in the terminal doesn't give me any logs to find out the problem.

You can add the debug option, like so: firejail --debug electron-mail.

Thanks for the heads' up! I commented it out as you said and I am also making use of the --debug option.

So here is another problem:

But it worked after I commented out seccomp !chroot
Sadly, adding in --seccomp doesn't seem to work and here's the log:
