Well trust me. I spent almost 2 hours trying to find out why my web page lags (I'm a web developer). And then when I disabled this addon everything was working smooth again. Download it at your own risk. Checked with operating system Windows 7 64bit.
Fixed the bug mentioned by you. Thanks for reporting this bug. We are now doing all the requests asynchronous. So it will not cause any lag or delay. Please try the addon again and give me your feedback. Thanks
Hi Indezoo, Its working for your site and showing the Correct Pagerank 4. Google Pagerank take some time to get updated and its variable. Please use the addon and give me the review again. Thanks for using the addon.
