I use Google Chrome on my Debian laptop, but at one point I had Firefox installed. Now I'm developing a GTK application, and when I click on a link, it outputs this:
(charry.phpw:6267): Gtk-WARNING **: Unable to show 'http://t.co/nOOjE9u1': Failed to execute child process "/opt/firefox/firefox" (No such file or directory)
I don't understand why it would be calling for Firefox, because I have x-www-browser set to Chrome. Does anyone have insight as to how GTK picks a browser to open hyperlinks?
Now I have to expand this question. I woke up this morning and tried to run this application on my Windows box, but it says:
<php.exe:3360>: Gtk-WARNING **: Unable to show 'http://t.co/tKtwKbAt': No application is registered as handling this file
So how does GTK register URI handlers? No one on the Internet seems to know how to do this...without Gnome, at least.
