The Opera browser is great, but it does not run on Nokia Series 40 devices. Even with accelerator proxy support, it still makes heavy use of the Series 60 device's network and CPU resources, since it still needs to parse and render the HTML code. If you want to browse HTML pages from a Nokia Series 40 device or use a browser that runs faster on a Nokia Series 60 device, you can choose Reqwireless's Java-based web client, called WebViewer.
The idea behind WebViewer is to push the browser proxy to the limit. The WebViewer client is only 48 KB, and you can install it on even first-generation Series 40 devices, such as the Nokia 7210. Without the proxy, the browser cannot render any web pages. In fact, the browser is configured to connect to the proxy only. The proxy not only fetches and resizes web content on behalf of the browser, but also parses the HTML and decides how to render the page. These rendering instructions, together with any embedded images and other media objects, are returned to the WebViewer browser in a highly compressed, proprietary binary format. This way, the device browser does not need to parse the HTML and manage the layout. It simply follows the well-formed instructions from the proxy to place text and images at specified places on the screen. The proxy renders the page to fit the device's screen size so that you will never need to scroll horizontally (similar to the SSR mode in the Opera browser).
