I am trying to open the cloud provider Internxt's desktop app. I have Librewolf installed, which I'm sure is going to work as a substitute for Firefox. Can I

ln -s /usr/bin/librewolf /usr/bin/firefox  

to make their app use Librewolf instead, thinking it's actually executing Firefox? If not, would an alias work?

You might want to configure xdg to open what you want instead.

Thanks! I'll bookmark this since I should learn xdg someday, but not today. 🤣 For now, this ln fakery worked. 😅

You can use the update-alternatives command with the x-www-browser key to create the symlink and let the system manage it.

It seems to me that having the symbolic link in /usr/bin would cause an error if you tried to install Firefox. It might be better to place the symlink in /usr/local/bin.

Eh, i just symlink the executable to ~/.local/bin/xdg-web and set that in the Webbrowser shortcut. There's a bunch of xdg- links now and i know with a ls -l what's what.

Oh, well... xD Maybe next time then. I guess the only difference in my case is that xdg still looks through all possible executables until encounteres Firefox? While your solution doesn't have to run through them all, but immediately jumps to the browser of your choice?

Thanks! I don't see myself ever installing Firefox, but I'll definitely read up of the differences between local/bin and "normal" bin. :)

Exactly. I've found xdg's script with a switch case cumbersone with my custom script (and ugly), while the other stuff is good enough for open-with. So i just "wire" the defaults, while keeping to a naming scheme.

Edit: in hindsight, this sounds confusing, huh?
