Ui.click hold context menus
From MozillaZine Knowledge Base
On the Macintosh, many users do not use a two-button mouse. In the mid-â€™90s, Netscape started using the convention of â€œclick-and-holdâ€ to provide access to the context menu. Later, Apple standardized Control-Click as the way to access context menus. For backwards compatibility, Mozilla still supports â€œclick-and-hold.â€ This preference determines whether or not the context menu will be shown when clicking and holding down the primary mouse button on a Macintosh.
Possible values and their effects
Holding down the primary mouse button will show the context menu.
â€œClick-and-holdâ€ does nothing; Control-Click is the only way to show the context menu.
Note: On Gecko 1.8.0 (Firefox 1.5 etc) this is hard coded to TRUE on OS X and FALSE on all other platforms. The preference did not exist then and if manually created has no effect.
