I need to get text of currently displayed page from extension.

var wm = Components.classes["@mozilla.org/appshell/window-mediator;1"]
                  .getService(Components.interfaces.nsIWindowMediator);
       var mainWindow = wm.getMostRecentWindow("navigator:browser");
       
alert(mainWindow.getBrowser().selectedBrowser.contentDocument.getSelection().toString()) 


This returns only selected text. I need to get all text content but has 
no glue how to do this.
Please help.

mainWindow.getBrowser().selectedBrowser.contentDocument.innerHTML/
innerText ?

or, if you want the text in some element with id=3Deleid:

gBrowser.selectedTab.contentDocument.getElementById('eleid').innerHTML/
innerText

 mainWindow.getBrowser().selectedBrowser.contentDocument.innerHTML

does not work 

mainWindow.getBrowser().selectedBrowser.contentDocument.innerText

In error console I see 

Warning: reference to undefined property mainWindow.getBrowser().selectedBrowser.contentDocument.innerText

no idea why it doesn't work

I think there is a simpler way to get the tabbrowser element of the
firefox interface: just use 'gBrowser', check out the code snippet
section of MDC
