Pagerank indicator not working in Google Toolbar?

I’m using Firefox for my regular SEO work. In my browser Google toolbar, Pagerank indicator always shows gray and ‘unranked’ status. Even I have install the search status addon for firefox but it showing no pagerank information available for every website which I open in my browser.Already I uninstall FF and reinstall it, the same problem occurs. Even I have reinstalled Google toolbar also. Any one please help me.
Note: Even http://www.google.com shows pagerank N/A.

I personnaly notice that some PR tools have a bad updates system. I used a PR toolbar in the past too, but the best way to check Page rank is to do it directly in website like http://www.pageranke.com
