Automate login process of our specific sites in firefox :

 There are two modes available in firefox : 
(1) simple(General) Mode : In this mode firefox will open as normal.
(2) Automate mode : which is password protected and verify password online/offline 
                             - In this mode we can set our specific sites URL with username and password and firefox 
                               will automatically login to desired site which we select from the list.
                             - This functionality will help a lot to developer as well as frequently users on different
                               applications. 
                             - These can be done same as web Test automation (for ex. Selenium webdriver api).
