Well, finally, use Internet Explorer haters and Mac lovers can have a toolbar that displays the Google PageRank. All you need is the Firebox browser and then a few plugins. The download instructions and thread at WebmasterWorld discuss just that. Here are the instructions again:
1. Download FireFox browser from http://www.mozilla.org/products/firefox/2. Install the GoogleBar Mozilla extension from http://googlebar.mozdev.org/
3. Install the PR indicator extension from http://toolbar.nickstallman.net/
I have installed it on my Firebox browser and its cool. It does take a few noticeable seconds to display the PageRank but its still cool. Here is a screen shot from my corporate site on Firebox with PageRank.
