Get Google page rank in the Firefox statusbar

If you are like me, then you want to be aware of the page rank of the site you are viewing. Also, if you are like me then you are browsing the web using Firefox. The Google Page Rank extension gives you the page rank in Firefox in a very convienent place, the statusbar (bottom of the browser window).

I also came across ListZilla which catalogs and lists all the extensions you have installed.
