firefox: How to open other programs?

[lonelypositron]

Hi,

I am not sure how to handle this properly so I am asking this here.
I need to be able to open from firefox, my default browser on some distro, some other app through the xdg link.
We are talking about trivial stuffs like deezer or tidal. But also more important stuff like jetbrains.
I am not quite sure how to do that because the firejail for frirefox is very effective and does not permit that. Which is quite alright. IT is what is should be. But How can I slightly modify it to open maybe specific links?

Thanks in advance for your help

I need to be able to open from firefox, my default browser on some distro,
some other app through the xdg link. We are talking about trivial stuffs
like deezer or tidal. But also more important stuff like jetbrains. I am not
quite sure how to do that because the firejail for frirefox is very effective
and does not permit that. Which is quite alright. IT is what is should be.

It should be doable if firefox is calling the other programs through IPC (such
as through dbus).

If that's the case, you can try to figure out (with something like d-feet)
which dbus methods it calls to open a program and allow it in the profile.

For example, if it calls program Foo with the foo.bar.baz method, you can
allow it in firefox-common.local:

dbus-user.talk foo.bar.baz

Feel free to post the methods found.

Though note that the more programs are allowed to be called outside of the
sandbox, the less effective the sandbox becomes.

But How can I slightly modify it to open maybe specific links?
