If you haven’t got your hands on the final release of Firefox 4, you can download the Windows 32 bit version in English U.S. from the link at the bottom of this article. I am currently using the final release version of Firefox 4 to write this article and to share my observations with you.

After upgrading my add-ons to the latest versions, everything seems to be working properly.

Those who have tried the beta are already familiar with the graphic user interface [GUI]. It is totally different from past versions of Firefox and uses a look a la Google Chrome with the tabs up on top. I actually prefer the tabs up on top. Since I started using Google Chrome as my primary browser because of a compatibility issues using Zemanta, I have adapted easily to this feature. You also have the option to turn off tabs on top if you wish.

Memory usage, which has always been a bone of contention for me, has not improved. After running Firefox 4 for less than an hour, memory soared to 223,556K , according to Process Explorer. Though some have claimed that memory usage has improved, I haven’t seen it.

Speed. Everyone wants to talk about speed. Plus everyone wants to claim that their browser is the fastest. Today, every browser is fast — or is it the browser’s connection speed to the Internet that is fast? For those of you who are still on dial-up, no browser is going to be speedy. For those who use broadband, I seriously doubt that one will be able to see any speed difference as pages render quickly before your eyes.

What is going to separate and differentiate all of the browsers is when everyone starts to use all of the new versions and we can determine which browser is more secure.

Download a copy of Firefox 4 for yourself and let us know what you think.

Comments welcome.
