Sleipnir 3 for Windows Web Browser isn't just powerful. It also includes a feeling that encaptures you from the moment you touch it. The feeling when using the easy tab switching of the all new full screen mode makes everyday browsing a much more pleasant experience. Sleipnir 3 for Windows Web Browser starts in an instance, even when opening hundreds of tabs. There is also no waiting time when opening a mass of bookmarks at one time. We have made daily browsing a much more speedy process by incorporating tab groups with many ideas.
