SecBrowser Guide Update Suggestion

Support
1

May the devs update SecBrowser’s guide? The archived guides are outdated.

Although SecBrowser is currently unsupported, users seeking browser alternatives and also Tor users may benefit from an updated SecBrowser guide in using Tor Browser without its network (along with a VPN/proxy):

  1. Uniformity: same browser fingerprint as millions of Tor Browser users have.
  2. Freedom: access a website that discriminates against the Tor Network.
  3. Speed: download/upload faster than the Tor Network.
  4. Convenience: a hardened Firefox by default.

Summary

*** VPN users: Manual Method (Version 10)

Step I: Make a copy of Tor Browser and rename it.

Step II: Create autoconfig.js.

  1. Copy these 2 lines into a text editor:
    pref(“general.config.filename”, “firefox.cfg”);
    pref(“general.config.obscure_value”, 0);
  2. Replace each quotation mark by retyping them. (Because whonix.org converts programmer quotation marks to curved ones).
  3. Convert the newline to LF. (Windows: Use an advanced text editor like Notepad++).
  4. Save as: autoconfig.js. (Windows: File, Save As, Save as type, All Files, File name: autoconfig.js).

Step III: Create firefox.cfg.

  1. Copy these 5 lines into a text editor:
    // IMPORTANT: Start your code on the 2nd line
    lockPref(“extensions.torlauncher.start_tor”, false);
    lockPref(“network.dns.disabled”, false);
    lockPref(“network.proxy.socks_remote_dns”, false);
    lockPref(“network.proxy.type”, 0);
  2. Replace each quotation mark by retyping them. (Because whonix.org converts programmer quotation marks to curved ones).
  3. Optional for firefox.cfg: Convert the newline to LF.
  4. Save as: firefox.cfg. (Windows: File, Save As, Save as type, All Files, File name: firefox.cfg).

Step IV: Copy autoconfig.js and firefox.cfg into the renamed Tor Browser directory.

  1. autoconfig.js file path:
    Windows or Linux: …\Browser\defaults\pref
    MacOS: …/Contents/Resources/defaults/pref
  2. firefox.cfg file path:
    Windows or Linux: …\Browser
    MacOS: …/Contents/Resources

Version History

Since Tor Browser version 9, these configurations reset upon restarting firefox.exe:
network.proxy.socks_remote_dns
network.proxy.type

Since Tor Browser version 10, this must be set to false:
network.dns.disabled

Since Tor Browser version 10, these environment variables no longer work:
TOR_SKIP_LAUNCH=1
TOR_TRANSPROXY=1
