Re: Org links and Flatpak firefox

[Ken Mankoff]

Hi Max,

Thanks for the debugging suggestions. It helped me figure out that the problem 
was us usual human error.

Emacs opens URLs in the last-active (from the UI perspective) firefox, even if 
there is a firefox on the current virtual desktop. I had 
"browse-url-generic-program" set to a script that used xdotool to find if there 
was a firefox on this desktop, and then sent the URL there. xdotool doesn't 
play nice withe flatpak, and that was the problem.

Thanks again for the suggestions,

  -k.
