Solipsism Browser is a third-party, open-source browser based on Chromium, launched just over three months ago. It features a unique side-rail design for navigation buttons, allowing for ergonomic one-handed use, especially on larger devices. Users can customize the homepage with HTML and CSS, and it includes a built-in ad blocker powered by uBlock Origin and a malware scanner. However, it lacks extension support, which is a strength of Firefox, and the address bar's placement at the top can hinder one-handed usability. Solipsism is not available on the Google Play Store and requires updates through platforms like F-Droid or Obtanium. The developer plans to create a future version based on the Servo engine.
