-/*** 2697: USER AGENT (UA) SPOOFING
- Spoofing your UA to *LOWER* entropy *does* *not* *work*. It may even cause site breakage
- depending on your values. Even if you spoof, like TBB (Tor Browser Bundle) does, as the
- latest ESR, it still *does* *not* *work*. There are two main reasons for this.
- 1. Many of the components that make up your UA can be derived by other means. And when
- those values differ, you provide more bits and raise entropy. Examples of leaks include
- navigator objects, resource://URIs, <isindex> locale, feature detection and more.
- 2. You are not in a controlled set of significant numbers, where the values are enforced
- by default. It works for TBB because for TBB, the spoofed values ARE their default.
- * We do not recommend UA spoofing yourself, leave it to privacy.resistFingerprinting (see 4500)
- * Values below are for example only based on the current ESR/TBB at the time of writing
