How do I change Librewolf (AppImage) to be my default browser on Linux Mint?

[Rayser]

In the Preffered Applications there is no LibreWolf option. I think it's because I'm using the AppImage version.

But can be done?

Try this tactic:

Open your preferred file manager to go to a directory or folder that has an html file. Select one of the html files with a right-click to choose Open with and point it to LibreWolf. If Librewolf is not shown, I believe most file managers will let you pinpoint the LibreWolf application -- sometimes the icon acts as a hint.

If you tried the above approach, and it did not work, tell us which step messed you up.

The LibreOffice AppImage appears on the Preferred Applications after changing the default HTML app to LibreWolf.

Now if I click on a link it's open LibreWolf, but a blank page, not the link itself.

At least, you're getting somewhere...somewhere warmer, not colder

All you have to do is edit the entry to say "Librewolf filename" or "Librewolf &1" . In either of these cases, you can type in the terminal Librewolf filename and it should work.

That's it.

I don't get it.

Open up a terminal application; you know how to do this part. The toolbar probably has an icon for terminal on the bottom of your screen.

One way to start figuring out stuff in Linux is, for the most part, typing in commands on a command line. Sure you probably have avoided it for most of your computer life, but sooner or later you will have to work some magic. It's time to crack those knuckles and enter the command

which LibreOffice

and the response should point you to where the command is,e.g. /usr/share/bin

and you can run it like this /usr/share/bin/LibreWolf my-new.html and it should present you with a new (blank) html.

Maybe next response should be 'I don't understand xxx part'

Give it a shot
