Xfce Change program launcher icon theme/desktop-wide?

[Espionage724]

With Chicago95 theme, Firefox defaults to "firefox" icon which is a Netscape-themed icon. "firefox_2" is a Firefox-themed icon. I can right-click Firefox in Whisker menu to change to "firefox_2" in the app launcher list, but "firefox" (Netscape icon) is still used for title bar/window list taskbar.

Is there a way to globally set the "firefox_2" icon for Firefox everywhere? I'm thinking something like gsettings set firefox-icon firefox_2 or a dconf.

This quick-fix works:

Get Icon files:

pkg info -l 'chicago95' | grep 'firefox_2'

Replace firefox with firefox_2:

ln -F -f -s -v '/usr/local/share/icons/Chicago95/apps/16/firefox_2.png' '/usr/local/share/icons/Chicago95/apps/16/firefox.png' && ln -F -f -s -v '/usr/local/share/icons/Chicago95/apps/32/firefox_2.png' '/usr/local/share/icons/Chicago95/apps/32/firefox.png' && ln -F -f -s -v '/usr/local/share/icons/Chicago95/apps/48/firefox_2.png' '/usr/local/share/icons/Chicago95/apps/48/firefox.png' && ln -F -f -s -v '/usr/local/share/icons/Chicago95/apps/scalable/firefox_2.svg' '/usr/local/share/icons/Chicago95/apps/scalable/firefox.svg'
