A (Mobile)Safari-like web browser for iOS (wrapping around UIWebView, of course) with a design goal of increased security and privacy.

Current builds are available for free in the App Store.

Basic browser functionality implemented:

• Basics of entering URLs, following redirections, back, forward, cookie storage, HTTP basic authentication

• Multiple tabs with support for window.open() and <a target="_blank"> automatically opening new tab windows, but blocks calls not made via user interaction events (similar to most desktop browser popup blockers)

• Bookmark list with management, re-ordering, and editing

• Custom long-press menu for links to open in a new tab, and to save images to the device; shows image or link alt text (useful for sites like xkcd)

• Swipe left and right to go back and forward

• Search from URL bar with DDG, Google, or Startpage

• Optional dark/night-time interface

Security and privacy-focused features implemented:

• Per-host/domain security and privacy settings:

  • Disables SSL 2 and SSL 3 by default with a configurable minimum TLS version to require from the host, such as TLS 1.2-only. Also disables weak TLS ciphers.

  • Configurable security policy:

    • Open (default, normal browsing mode)

    • No after-load connections (blocks XMLHTTPRequest/AJAX requests, WebSockets, and <video> and <audio> elements)

    • Strict (blocks all of the above plus embedded fonts and Javascript)

  • Blocks mixed-content requests (http elements on an https page) unless disabled (useful for RSS readers), shows broken padlock

  • Blocks pages loaded from non-local networks (i.e., the internet) from trying to load sub-requests (e.g., images, iframes, ajax) from hosts that are on local RFC3330 networks such as routers and other insecure devices

  • Defaults to only accepting cookies and local storage for the duration of the session (until the last tab accessing that data closes) but allows persistent storage from configured hosts

• Auto-destroys non-whitelisted cookies and local storage (even within the same tab) that has not been accessed by any other tab within a configurable amount of time (defaults to 30 minutes) to improve privacy while browsing within a long-running tab

• Cookie and localStorage database listing and deletion per-host

• Integrated full HTTPS Everywhere ruleset to do on-the-fly URL rewriting to force requests over SSL where supported, including setting the secure bit on received cookies and auto-detection of redirection loops

• HTTP Strict Transport Security (RFC6797) implementation (in addition to WebKit's mystery built-in one) with Chromium's large preload list

• Integrated URL blocker with a small included ruleset of behavior-tracking advertising, analytics, and social networking widgets (this list is intended for enhancing privacy and not to be an AdBlock-style comprehensive ad-blocking list)

• Shows locked padlock for fully SSL-encrypted URLs, and organization name for sites with EV SSL certs

• Integrated SSL certificate viewer by tapping on padlock icon, highlighting weak SSL certificate signature algorithms and showing per-connection negotiated TLS/SSL protocol version and cipher information

• Optional sending of Do-Not-Track header on all requests

• Integrated 1Password button to autofill website logins, passwords, credit card numbers, etc.; requires the 1Password iOS app to be installed (and is not enabled if not installed)
