I think its a must for all SEO and webmasters.It have two main options.

One for showing live PR and Alexa ranking.

Another for checking nofollow links.

This two will be very useful for SEOs during link building.They can make sure about the quality of backlinks.

Here's a very useful tool SEO Quake The firefox version seems to work better than the IE version.

 

I always use Firefox because its having a many wonderful Plugins

 

There are a variety of tools available on the net to check Alexa and PR. Some guys prefer to have inbuilt plugins, while others use external sites to check out the same.

The best and one of the only tools i use when doing SEO is Google.com
