// This is a Greasemonkey user script. To install it, you need
// Greasemonkey 0.5 or later: http://greasemonkey.mozdev.org/
// Then restart Firefox and revisit this script.
// Under Tools, there will be a new menu item to "Install User Script".
// Accept the default configuration and install.

// To uninstall, go to Tools/Manage User Scripts,
// select "Locator", and click Uninstall.

//
// This script is designed to make Rapattoni's Locator tool available to
// Firefox on Windows, Mac and Linux. The functionality implemented has
// been tested to work against two different MLS(s) using this system.
// In theory, it should work for many more. Any url patterns for such
// MLS(s) not included below, can simply be added through Firefox. To
// do so, under Tools/Manage User Scripts, select Locator then add
// Included Pages.
//
// This script includes the following functionality:
// Login:
// * Fixed NWMLS login, which disallowed Mac and Linux Firefox users.
// Navigation:
// * Provides replacement "pop-up" menus for all known navigation: Search, Listings,
// Contact, Links, Admin, Help. Menu items are dynamically created. Original
// menus were IE specific, and simply failed to operate in Firefox.
// Content:
// * No work has yet been done to review the functionality of content pages
// ( the pages that come up after choosing a menu item ).
