Auto-hide status bar in Mozilla Firefox

The Google Chrome browser has a nice status bar which automatically hides when it has done displaying all the information like downloading webpage, opening website etc. But the statusbar of Mozilla Firefox is static and stays visible all the time. If you want the statusbar of Firefox to imitate the auto-hide feature of its Chrome counterpart, then you can use the autoHideStatusbar add-on. Here is how :

1. Visit https://addons.mozilla.org/ in your Firefox browser.
2. Click on the yellow (may turn green in future) Add to Firefox button to install the autoHideStatusbar add-on.
   
3. Restart Firefox to complete the installation of the add on.
4. Once you have installed the autoHideStatusbar add-on, you will see that your Firefo statusbar has been hidden. The Firefox window would look something like this :
   
5. If you want the statusbar to appear again, then you can hover the mouse cursor over the usual statusbar region. You can also press the hotkey Ctrl + Alt + U to make the statusbar appear.
6. You can access the autoHideStatusbar add-on preferences from Firefox menubar Tools → Add-ons → Extensions. In the prefernces window, you can choose to enable or disable the add-on and when to show the statusbar (like when hovering over a link, downloading a file or a pge is loading etc.)
   
7. If you have a particular website where you would like to have the statusbar always display, then you can add the URL here in the AHS Filters section as shown.
   

The autoHideStatusbar add-on for Firefox can fulfill the needs of a person who is looking forward to have a Chrome's statusbar like auto-hiding statusbar in Mozilla Firefox. It not only works for Firefox browser but also in Thunderbird email client and the Flock browser.
