The Opera 8.52 browser has some nice features. It supports a "Small screen" viewing mode that simulates how web pages may appear on mobile devices with small displays. The browser also makes assists those with disabilities through its "Author" vs. "User" viewing modes. In the "User" mode, the browser strips away CSS styles and substitutes user text style preferences. There is also a "No images" button that turns off images. This provides an easy way to make sure all your images have appropriate alt text associated with them which is something important to keep in mind when designing for accessibility.
