Fully customizable per-site, of course.
- Keeps control in your hands
Override anything, from CSS to JS to cookies.
- Avoids much of the modern bloat of the web
With no Flash or WebGL to show you ads, or WebCL to run up your power bill, auto-playing loud ads are a thing of the past.
- SSL certificates handled in a SSH-like manner

This also nicely sidesteps pay-to-play schemes such as the Extended Validation, which gives a bigger green secure notification in common browsers.
- Performance and memory use are explicit goals
No JS extensions. All features are in native C/C++.
- Respects your privacy. URLs are never sent anywhere, unlike in certain other browsers
Similarly, the speed dial leaks no information to the site. No connection to the site is made, nor can the tile execute any JS when loading the speed dial page. The favicon is used if available, and it can only become available when you manually go to the site.
