How do I add my own message to the Firefox status bar using extjs?

actually I am developing one project with front end UI design using ex开发者_JAVA百科tjs. But when my project is loading on the Mozilla browser, on the status bar, done has not been displayed to all the pages. How can I add my own messages to the Firefox status bar using extjs?

There are two answers to this question: First, you don't even need extjs, you can just use javascript's window.status (https://developer.mozilla.org/en/DOM/window.status) to add your own text.

However...

Firefox by default disables the ability to change that status, and it has to be re-enabled on each browser in order for you to be able to see those changes.
