I'm trying to access firefox properties, more specifically the launcher options I'm given following instructions:
Ubuntu (and other GNOME-based distributions):
- Click on the Preferences menu and select Main menu. The Main Menu window appears.
- Click on the program group called Internet.
- Select Firefox Web Browser and click on the Properties button. The Launcher properties window appears.
- Insert the string
env LD_PRELOAD=/usr/lib/libGL.so.1before the text specified in the Command field:
However when I click on Firefox Web Browser under the program group called internet it simply opens another window, if I right click on it it also opens another window, where may I find the "properties button"?
