/*** [SECTION 1600]: HEADERS / REFERERS
|
||||
Only *cross domain* referers need controlling: leave 1601, 1602, 1605 and 1606 alone
|
||||
---
|
||||
harden it a bit: set XOriginPolicy (1603) to 1 (as per the settings below)
|
||||
harden it a bit more: set XOriginPolicy (1603) to 2 (and optionally 1604 to 1 or 2), expect breakage
|
||||
---
|
||||
If you want any REAL control over referers and breakage, then use an extension. Either:
|
||||
uMatrix: limited by scope, all requests are spoofed or not-spoofed
|
||||
Smart Referrer: granular with source<->destination, whitelists
|
||||
---
|
||||
|
||||
Expect some breakage e.g. banks: use an extension if you need precise control

||||

You should set the values to what suits you best.

- "Offline Website Data" includes appCache (2730), localStorage (2710),
|
||||
service worker cache (2740), and QuotaManager (IndexedDB (2720), asm-cache)
|
||||
- In both 2803 + 2804, the 'download' and 'history' prefs are combined in the
|
||||
Firefox interface as "Browsing & Download History" and their values will be synced

Privacy & Security>Delete cookies and site data when Thunderbird is closed (1681701)
|

* If you want to keep some sites' cookies (exception as "Allow") and optionally other site
|

data but clear all the rest on close, then you need to set the "cookie" and optionally the
|
||||
"offlineApps" prefs below to false, and to set the cookie lifetime pref to 2 (2703)
