Updated on Jun 01, 2009: The current developer version of Chrome supports extensions since May 12, 2009. I developed a PageRank Extension for Chrome, it's a really toolbar extension that automatically shows Google PageRank of the current web page.
Because Google Chrome current version doesn't support for Google Toolbar and Alexa Toolbar, so it's a lot of vistors of PageRank Status Checker. Unfortunately, Alexa blocked my server IP since Dec 2008. When you check the PageRank, the page always shows Server Busy. :-(
I just modified the server script and released version 2.0, this version uses Widgets method to receive the Alexa data, it works fine now.
I also changed the report interface. The screenshot of version 1:
