# Help Menu

Many of the commands in this menu use ImageJ's BrowserLauncher to open a Web page using the user's default browser. On Linux, with ImageJ 1.38k or later, BrowserLauncher looks for 'netscape', 'firefox', 'konqueror', 'mozilla', 'opera', 'epiphany' or 'lynx' and uses the first one it finds.
