I absolutely love Opera... Its so fast, useful, and those darned mouse gestures are what really keep me using it.
Opera has a mouse gesture system that is really the core of why I use it. By holding the right mouse button and waving the mouse around a bit, you can close one window, open another, and rearrange them all within Operas tabbed interface.
Opera also has this feature thats an auto-form-filler-in thing. You can have it remember your address, passwords, anything you like, then have it automatically fill out forms for you.
You can type g mouthshut in the address bar and it will do a Google search for mouthshut automatically. Or, maybe e antiques to do an eBay search for antiques.
Another strong point of Opera is that its so fast. After using Opera for a bit, I decided to open up MSIE to see what its like, and the load times were unbearable after using Opera. I really enjoyed it.
Operas so jam-packed with features that its insane! Anything you ever wanted from a browser can be found here in Opera!
Operas great, free, fast, powerful, and exciting to use! Try it now!
