This is a known issue. Its not really an issue just more of a limitation. When the messenger goes to open the link, it launches the browser itself, in the context of itself. Meaning the browser cannot access its files (due to the sandbox) and crashes/throws errors.

As for why links work in Firefox: it uses some weird way of keeping track of its instance and even if you run Firefox from in a sandbox, it'll somehow open the page in a currently running instance outside of the sandbox.

The workaround is to either use Firefox as your default browser, or manually copy/paste links when you need.

I'm sure there are issues that describe both in more detail, but I cannot seem to find any.

That was actually quite nice when it lasted, but it has stopped working a while ago.
If anyone has an idea for how to get Firefox to do this again, that'd be great!

I don't have nodbus set in this profile.

But https://github.com/glitsj16/firejail-handler-http looks great, thanks! Though I will have to understand the difference to https://github.com/glitsj16/firejail-handler-extra, they seem to be almost the same.

nodbus is deprecated and not set in any of your profiles. You must check for dbus-user xxx.
