Filed under: Internet , Windows , Freeware , Browsers Sleipnir is a web browser that's popular in Japan and pretty much unheard of in the rest of the world. The Windows-only browser lets users choose between the rendering engines used by market leaders Internet Explorer and Firefox. But Sleipnir is more than just a pretty front end for either browser. It's a standalone tool that provides users with a huge number of customization options. Fenrir, the company behind the free browser, has been making an English language version for a while now, but Computer World reports that the company is stepping up its efforts to promote the browser outside of Japan. Here are a few of the things that make Sleipnir worth checking out: If you install the optional Gecko plugin, you can switch between the Firefox and Internet Explorer rendering engines with the click of a button. You can do something similar with the IETab add-on for Firefox, but Sleipnir includes this functionality out of the box. When you select text, a box shows up on screen letting you search for that text on the web or translate the text from English to Japanese and vice versa. You can even plot a highlighted address on a map. You can extend the browser's functionality with scripts and plugins . There's also a portable version of Sleipnir that you can run from a flash drive. [via Digital Inspiration ] Read | Permalink | Email this | Comments ...
