Here's a little tutorial in order to run the Steam protocol with Firefox:
1. In Firefox, enter in the address bar:
about:config
2. A list of options appears, right-click and select:
New -> Boolean
Enter the name:
network.protocol-handler.external.steam
Validate -> In the new window, select
True then validate.
3. Again right-click,
New -> String
Enter the name:
network.protocol-handler.app.steam
Validate, in the new window enter the value:
steam
4. Final right-click:
New -> Boolean
Enter the name:
network.protocol-handler.warn-external.steam
Validate and this time select
False.
5. The following command must be used in root mode.
Please note that I use the nano text editor here because it's installed on all distributions, but it's not the easiest to use.
So I recommend replacing "nano" by your favorite text editor (vim, gedit, kate, ...)
In this file, enter:
#!/bin/sh
#
# Steam wrapper script
#
6. We must now find the command that launches
Steam,
usually it's:
Console:
nano ~/.PlayOnLinux/configurations/installed/Steam
(modify the path if PoL is not installed in the default directory)
Copy everything below:
#!/bin/bash
And paste it in the file you just created.
Add:
"$@"
(includint the quotes) after steam.exe
Which results in:
steam.exe "$@"
7. Run this command:
In root mode to be able to launch it.
Now links like "steam://" should launch properly.
