Orfox is a web browser for Android that is based on the same source code as the Tor Browser but with some privacy modifications added to it.
Basically, if you want to run Tor on Android, Orfox is probably your best bet when it comes to that as it is an official product by the Tor Project.
Setup is not overly complicated, but it requires more than just installing the Orfox application. You need to install the Orbot application for Android as well as Orfox requires it. Without it, you cannot use the web browser as all as it is configured to use the Tor network; Orbot connects to the Tor network, and that is why you cannot use the web browser without it.
Orfox: a Tor Browser for Android
Orfox prompts you to install Orbot on first run; if you have not installed the secondary application already, use the prompt to install it.
From there it is always necessary to start a Tor connection using the Orbot app first. Orfox is based on Firefox (as is the Tor browser), and it shows.
The Orfox browser ships with the NoScript and Tor Browser Settings add-ons. NoScript is a highly rated script blocker that supports other security protections on top of the core functionality.
You may access the Security Slider with a tap on menu and the selection of Orfox Settings. It is set to standard after installation and replicates the security slider of the desktop Tor browser (where the default level is named low).
Basically, what you can do is improve security by limit functionality that websites may use. If you switch to safer, the following restrictions are enabled:
- Audio and video media won't autoplay anymore. You need to tap on the media to start playback.
- Some fonts and math symbols are disabled.
Orfox shares many features with Firefox, but there are also differences:
- Orfox does not require Contacts, Camera, Microphone, Location or NFC permissions of Android.
- Orfox removes features such as WebRTC or support for interacting with casting devices. The reason given is that these are not compatible with "proxying communication through a TCP-based network like Tor).
- Proxying of all Java network HTTP communication through the local Orbot HTTP proxy.
Android users who run Orweb, the default browser for Orbot/Tor mobile users at the point in time may wonder whether they should switch to Orfox, or stick with Orweb right now.
One core difference between the two browsers is that Orweb is using the WebView component of the Android operating system. The developers don't have full control over the component which makes it difficult or even impossible to upgrade it directly or patch bugs. Orweb replicates only a limited number of tweaks that reduce browser fingerprinting.
Check out the official Orfox website for additional information. It lists download links that point to Google Play and F-Droid.
The developers plan to include mobile versions of NoScript, the Tor Browser Button and HTTPS Everywhere in a future release.
