Hi all,

I'm new to AEL. I'd like to use it for launching firefox on OSMC.
I've configured a simple launcher with the name and path to firefox (which is installed, of course).

When starting that launcher following error is shown in the log.

Launching blocking process subprocess.call()
Process retcode = 1
(see https://paste.kodi.tv/evudicecay.kodi for more lines)

Do you have any idea about it? Googling about it didn't really help.
Thanks a lot.

Retcode 1 means the process returns an error. It could happen if /usr/bin/firefox it's a script. Can you test the following? Change the app to /bin/sh and the use /usr/bin/firefox as argument.
