Otter Browser for Windows XP

Otter Browser, developed by Michał Dutkiewicz, is a cross-platform, open-source web browser that aims to recreate the best aspects of Opera 12.x in Qt. Currently, Otter Browser is one of the few web browsers that still support Windows XP. Updates will continue arriving indefinitely and provide further fixes to the browser. As of now, Otter is a solid browsing option but may lack features for daily use.
