1. READ the full README

|
|
3. If you skipped steps 1 and 2 above (shame on you), then here is the absolute minimum
|
|
* Auto-installing updates for Thunderbird and extensions are disabled (section 0302's)
|
|
* Browsing related technologies, and JavaScript disabled. Use your web browser for browsing.
|
|
4. BACKUP your profile folder before implementing (and/or test in a new/cloned profile)

These do rely on 3rd parties (Google for SB and Disconnect for TP), but many steps, which are

/*** [SECTION 1600]: HEADERS / REFERERS
|
|
Only *cross domain* referers need controlling and XOriginPolicy (1603) is perfect for that. Thus we enforce
|
|
the default values for 1601, 1602, 1605 and 1606 to minimize breakage, and only tweak 1603 and 1604.
|
|
|
|
Our default settings provide the best balance between protection and amount of breakage.
|
|
To harden it a bit more you can set XOriginPolicy (1603) to 2 (+ optionally 1604 to 1 or 2).
|
|
To fix broken sites (including your modem/router), temporarily set XOriginPolicy=0 and XOriginTrimmingPolicy=2 in about:config,
|
|
use the site and then change the values back. If you visit those sites regularly (e.g. vimeo), use an extension.
