Ask SI about Dillo

Answers use saved listing facts and recorded sources.

What it does

Dillo is a lightweight independent browser with a restrictive privacy policy, domain blocking and cookies disabled by default.

Dillo's manual is candid about the tradeoff: its default privacy policy can break website functionality. Cookies are off unless configured, and the browser does not implement JavaScript. That makes it more useful for reading compatible pages on a small system than for web applications that depend on scripts.

The manual also documents domain blocking and separate choices for session-only or persistent cookies. The project has moved to dillo-browser.org; the old dillo.org domain is no longer controlled by its developers.

Strengths

Cookies disabled by default
Configurable domain blocking

Watch out for

No JavaScript support and incomplete modern-web compatibility
