Includes rounding of DOMHighResTimeStamps and other
timers with resolution higher than 1 ms.
Behind "BraveRoundTimeStamps" feature flag, enabled by default.
Also: disable 2 linux browser tests broken by timer rounding
Create a feature flag, BraveTorWindowsHttpsOnly, that
enables HTTPS-Only Mode for Private Windows with Tor.
Enable that flag by default.
Do not enforce HTTPS-Only for .onion sites: these
are already secure when using http://.
(Users can check "Always use secure connections" to enable
HTTPS-Only Mode for other windows if they wish.)
* [Experiment] Vertical tabs
This new feature is at experimental stage for now. So it's hidden
behind flag('Vertical tabs')
Impemented:
* Expand and collapse via a button on top of tabs.
* Vertical scroll area for tabs
* TabCards
* Tab reordering via drag-and-drop
* Tab detaching and attaching via drag-and-drop
* Shape customization
TBD:
* Switching tabs layout direction on runtime
- need to plumb pref to many UI components.
* Title area in frame
- Show title or move up toolbar
- Moving up toolbar can take some time.
* Layout animation
* Bug 23170: anti-fingerprinting: hide screen size and window position
Disabled by default behind the kBraveBlockScreenFingerprinting flag.
When farbling is active, modify API behavior in 4 categories:
1. window.outer{Width,Height}, window.screen{X,Y},
window.screen.{width,height,avail{Width,Height,Left,Top}}
R = random number between 0 and 8, seeded by session+domain
window.screen{X,Y} -> R
window.outer{Width,Height} -> window.inner{Width, Height} + R
window.screen.{width, height} -> window.inner{Width, Height} + R
window.screen.avail{Width, Height} -> window.inner{Width, Height} + R
window.screen.avail{Top, Left} -> R
window.screen.isExtended -> false
2. {mouse,drag,pointer,touch}Event.screen{X,Y}
Rewrite Event screen coordinates such that
event.screen{X,Y} -> devicePixelRatio * event.client{X,Y} + R
3. device-{width,height} in media queries
When farbling is enabled, media query for device-width
matches the same value as window.screen.width (also farbled).
Same for device-height.
4: make window.open play nice with spoofed screen coords
When a web page opens a child window, the position of the child window
should be relative to the spoofed screen coordinates, not relative
to the real screen coordinates.
Also:
* Factor out brave_session_cache.{cc,h} to speed up incremental builds.
* Add browser tests of these protections.
* Suppress upstream browser tests that expected isExtended to be true sometimes.
* Set the feature flag to be disabled by default. (We will be rolling
out enabled over griffin.)

fix https://github.com/brave/brave-browser/issues/24205
Querying channel info caused crash at startup because channel info
is not set on Windows Release build for unittest.
Do filtering playlist feature via unexpire_flags.cc instead.
* Implement navigator.languages farbling
* add support for HTTP headers
* add support for farbling HTTP header
* add reduce language preference toggle in settings
* Implement font whitelist

* rebase patches
* use anonymous namespace
* also add our AllowFontFamily method to TestFontSelector to avoid compile errors
* farble all non-whitelisted fonts without enumeration
* rename to MakePseudoRandomGeneratorForURL
* move session token management to singleton service
* move font whitelist to .cc file
* move prefs constants and code around
* pref names browsertest fix
* reduce patches (really)
* add web worker and service worker tests

* lint
* default session key to 12345 if command line switch is missing
https://github.com/brave/brave-browser/issues/22021
* change 12345 -> 23456 so it doesn’t match the test default
