Missing Firebug Icon on to Status Bar or Add-on Bar | Firefox 5

How to bring back the Missing Firebug Icon on to Status Bar or Add-on Bar?

After Upgrading to Firefox 5.0, i noticed the Firebug Icon moving on to the top right corner of the browser. (See the Pic Below). But i always feel very muck comfortable using Firebug addon from the bottom right corner of the window.

I have used firebug to design most of my personal websites like
Factsbite - For all Exam Related Results
Daily Results - University Results and Recruitment across India

I finally decided to move the Icon back to the same old position. Here are the steps to do it.

1) From Your Firefox, open the page about:config
2) Firefox will warn you about changing the advanced settings. Click on the button below to continue.
3) Search for the extension, "extensions.firebug.showStatusIcon". Double click to set the value to true. (Right click and Toggle will also work).

Now you can see the Firebug on the bottom bar which was missing or disappeared.
