I have been using at work and home, Firefox 3 for several days and I am quite satisified with the quality of the release. The memory leak issue seems to be much better now though I think for my part, I only worsen it with the variety of plugins I use.

The “Awesome Bar” I have found useful and not an impediment to my browsing as many others have complained.

However, what I will see from FF3 will be speed in rendering and better security along with other under the hood improvements, not so much in the interface portion of the app which in reality I do not forsee to change much in the next few releases as people are comfortable in the way the browser is set up.
