Full-featured web browser with support for the Gecko engine

If you're tired of your old web browser, try using alternatives which, despite not being very well-known, they work perfectly well. One of them is Sleipnir. 

An alternative to the big players not to be stifled with

Sleipnir is a complete web browser that can fully replace Internet Explorer or Firefox. In fact, it uses the Internet Explorer core engine but you can replace it by the Mozilla Gecko engine if you want. Sleipnir also comes bundled with Roboform, a handy password and web form manager.When running Sleipnir for the first time, you can import data from quite a varied amount of browsers. I must say however that my first impression of Sleipnir wasn't very good: the interface is simply bloated with buttons and toolbars, too many for someone like me who loves minimalist design.

A safe option that makes this a worthwhile idea

That said, Sleipnir does have many positive sides to it. You can browse the web comfortably (thanks to its powerful tab management system) and safely (with a wide array of security tools). Sleipnir also features a complete built-in search tool, an RSS manager similar to Firefox Live Bookmarks, support for proxy servers and many other interesting tools. Sleipnir is a powerful alternative web browser that's definitely worth a try, even if you're happy with your current browser.

    Sleipnir. I have been using Sliepnir for some time. It was well known as the most customizable browser out there. It was the oly browser to be able to display in the colours (menus, tabs etc.) necessary for a partially sighted person like me to see. Sleipir 3 won't do anything. It is not worth downloading - absolute garbage and gobbledy gook.

    Handles tabs well. I like browsers that open new pages in new tabs - like SlimBrowser - this one does the job. I have found it to be very stable and the plugin handling is excellent e.g. Roboform works fine. I won't use any browser that can't handle Roboform. Pros: Very stable
