A significant release of the specialized Tor Browser 12.0 has been formed, transitioning to the ESR branch of Firefox 102. The browser focuses on ensuring anonymity, security, and privacy, with all traffic routed only through the Tor network. Direct access via the current system's standard network connection is impossible, which prevents tracking the user's real IP address (in the event of a browser hack, attackers could access system network parameters, so products like Whonix should be used to completely block potential leaks). Tor Browser builds are prepared for Linux, Windows, and macOS. The formation of a new version for Android is delayed. <\/p>\n
To provide additional protection, Tor Browser includes the HTTPS Everywhere extension, allowing encryption of traffic on all sites where possible. To mitigate threats from JavaScript-based attacks and to block plugins by default, the NoScript extension is included. To combat traffic blocking and inspection, fteproxy and obfs4proxy are utilized. <\/p>\n
To establish an encrypted communication channel in environments that block any traffic other than HTTP, alternative transports are offered, which allow, for example, bypassing attempts to block Tor in China. To protect against tracking user movement and to avoid exposing characteristics specific to individual visitors, APIs such as WebGL, WebGL2, WebAudio, Social, SpeechSynthesis, Touch, AudioContext, HTMLMediaElement, Mediastream, Canvas, SharedWorker, WebAudio, Permissions, MediaDevices.enumerateDevices, and screen.orientation are disabled or limited, along with telemetry sending tools, Pocket, Reader View, HTTP Alternative-Services, MozTCPSocket, 'link rel=preconnect', and a modified libmdns. <\/p>\n
In the new version: <\/p>\n
\n
The code base has transitioned to Firefox 102 ESR and the stable branch tor 0.4.7.12.\n
Multilingual builds are provided \u2014 previously, a separate build was required for each language, but now a universal build is available that allows for on-the-fly language switching. For new installations in Tor Browser 12.0, the language corresponding to the locale set in the system will be automatically selected (the language can be changed during use), and when transitioning from branch 11.5.x, the previously used language in Tor Browser will be retained. The multilingual build takes about 105 MB.
<\/center>\n
In the Android version, the HTTPS-Only mode is enabled by default, wherein all requests made without encryption are automatically redirected to the secure versions of pages («http:\/\/» is replaced with «https:\/\/»). This mode was included in the last significant version for desktop builds.\n
In the Android version, a setting called «Prioritize .onion sites» has been added to the «Privacy and Security» section, which ensures automatic redirection to onion sites when attempting to open web pages that issue the HTTP header «Onion-Location», indicating the presence of a site variant in the Tor network.\n
Interface translations have been added for Albanian and Ukrainian languages.\n
The tor-launcher component has been redesigned to facilitate the launch of Tor for Tor Browser.\n
The implementation of the letterboxing mechanism has been improved, adding padding around web page content to prevent identification by window size. The option to disable letterboxing for trusted pages has been provided, the removal of one-pixel borders around fullscreen videos has been implemented, and potential information leaks have been addressed.\n
After conducting an audit, support for HTTP\/2 Push has been enabled.\n
Data leaks regarding locale through the Intl API, system colors via CSS4, and blocked ports (network.security.ports.banned) have been prevented.\n
The Presentation API and Web MIDI have been disabled.\n
Native builds for Apple devices with Apple Silicon chips have been prepared. <\/ul>\n
