Safe Browsing is designed to protect users from malicious sites. Tracking Protection is designed

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

This sub-section has been redesigned to differentiate between "real-time"/"user initiated" data

those lists. There are NO privacy issues here. *IF* required, a full url is never sent to Google,

swear it is anonymized and only used to flag malicious sites/activity. Firefox also takes measures

|
such as striping out identifying parameters and storing safe browsing cookies in a separate jar.

/*** [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.
