In Firefox… sometimes you might have noticed that  the cursor starts blinking on the screen. It might happen when you click on any element on the page , a division or an image etc. This Blinking Cursor in the browser window is actually an ACCESSIBILITY Feature of FireFox called ‘caret browsing’. This features  allows/enables  users to select text on the page with the keyboard ( Which we normally tend to do with the use of our mouse).

Well! if you donot want this feature … simple press “F7” to toggle it to false  and vice-versa ( if you want it ON).  You could also  type “about:config” in the address bar (type in “caret” in the filter box) and simply double click to change the option “accessibility.browsewithcaret” from “true” (turn caret browsing ON) to “false” ( turn caret browsing OFF)
