Do you use Google Chrome as your primary browser? If not, you probably should be.
Now, don't get me wrong, there are other browsers that are very good. Such as Firefox, Opera, Safari and others. But the one I would recommend is Chrome by a long shot.
Why? A few reasons.
Extensions. Yes, other browsers have extensions, but the way they're handled in Chrome is better. For example, in Chrome if you install or uninstall a theme or extensions you do NOT have to restart the browser. It takes full effect right away.
Multi-threaded. This is a big one. In Google Chrome, all tabs and plugins are separate threads in Windows. This gives it a small edge with multi-cored systems and more importantly adds greatly to stability. If one of your tabs or a plugin (such as flash) crashes, it won't take the rest of the browser with it. This also makes it handle RAM more effectively.
Design. It's design is very streamlined. Instead of an URL bar and a search bar you just have one that works as both. It works very well. Everything else about it is compact but functional.
