Download QupZilla Appimage

Download the file, make it executable from its Properties window, and finally run the Appimage to launch QupZilla web browser:

Don’t see the “Run” option even after made the Appimage executable? Go to file manager’s menu Edit -> Preferences -> Behavior -> Choose the option says ‘Run executable text files when they are opened’.
