Bug 1787790: Normalize system fonts with RFP on. r=emilio

System fonts can leak any user customization of system fonts, or user's
locale (e.g., en-US and ja Windows have different system fonts).
Also, Linux distributions/desktop environments set default fonts in
different ways.

Customization can be detected either with font metrics, the font allowed
list is not enabled or the font is included in it, or with
getComputedStyle, that leaks the name of the font that Firefox tries to
apply.

This patch try to prevent these leaks by using a generic "sans-serif"
for all system fonts, except on macOS, where it uses "-apple-system",
and on Android, where these fonts always use Roboto.

Bug 1907726 - Make sure WebTransportSessionProxy::NotifyDatagramReceived is called after OnStopRequest,  a=RyanVM

The crash occurs because WebTransportSessionProxy::OnDatagramReceivedInternal is called before WebTransportSessionProxy::OnStopRequest.
When this happens, WebTransportSessionProxy::mTarget is the main thread, so a task is dispatched to the main thread. This causes WebTransportSessionProxy::NotifyDatagramReceived to be called on the main thread.

If WebTransportSessionProxy::NotifyDatagramReceived is invoked while WebTransportSessionProxy::mStopRequestCalled is true, it can lead to OnDatagramReceived being called on the main thread (instead of the socket thread), resulting in a crash.

(removed in https://bugzilla.mozilla.org/917049)

Bug 14952: Enable http/2 and AltSvc

In Firefox, SPDY/HTTP2 now uses Origin Attributes for
isolation of connections, push streams, origin frames, etc.
That means we get first-party isolation provided
"privacy.firstparty.isolate" is true. So in this patch, we
stop overriding "network.http.spdy.enabled" and
"network.http.spdy.enabled.http2".

Alternate Services also use Origin Attributes for isolation.
So we stop overriding
"network.http.altsvc.enabled" and "network.http.altsvc.oe"
as well.

(All 4 of the abovementioned "network.http.*" prefs adopt
Firefox 60ESR's default value of true.)

However, we want to disable HTTP/2 push for now, so we
set "network.http.spdy.allow-push" to false.

Bug 26146: Spoof HTTP User-Agent header for desktop platforms

In Tor Browser 8.0, the OS was revealed in both the HTTP User-Agent
header and to JavaScript code via navigator.userAgent. To avoid
leaking the OS inside each HTTP request (which many web servers
log), always use the Windows 7 OS value in the desktop User-Agent
header. We continue to allow access to the actual OS via JavaScript,
since doing so improves compatibility with web applications such
as GitHub and Google Docs.

Bug 12885: Windows Jump Lists fail for Tor Browser

Jumplist entries are stored in a binary file in:
  %APPDATA%\\Microsoft\Windows\Recent\CustomDestinations\
and has a name in the form
  [a-f0-9]+.customDestinations-ms

The hex at the front is unique per app, and is ultimately derived from
something called the 'App User Model ID' (AUMID) via some unknown
hashing method. The AUMID is provided as a key when programmatically
creating, updating, and deleting a jumplist. The default behaviour in
firefox is for the installer to define an AUMID for an app, and save it
in the registry so that the jumplist data can be removed by the
uninstaller.

However, the Tor Browser does not set this (or any other) regkey during
installation, so this codepath fails and the app's AUMID is left
undefined. As a result the app's AUMID ends up being defined by
windows, but unknowable by Tor Browser. This unknown AUMID is used to
create and modify the jumplist, but the delete API requires that we
provide the app's AUMID explicitly. Since we don't know what the AUMID
is (since the expected regkey where it is normally stored does not
exist) jumplist deletion will fail and we will leave behind a mostly
empty customDestinations-ms file. The name of the file is derived from
the binary path, so an enterprising person could reverse engineer how
that hex name is calculated, and generate the name for Tor Browser's
default Desktop installation path to determine whether a person had
used Tor Browser in the past.

The 'taskbar.grouping.useprofile' option that is enabled by this patch
works around this AUMID problem by having firefox.exe create it's own
AUMID based on the profile path (rather than looking for a regkey). This
way, if a user goes in and enables and disables jumplist entries, the
backing store is properly deleted.

Unfortunately, all windows users currently have this file lurking in
the above mentioned directory and this patch will not remove it since it
was created with an unknown AUMID. However, another patch could be
written which goes to that directory and deletes any item containing the
'Tor Browser' string.  See bug 28996.

Bug 22548: Firefox downgrades VP9 videos to VP8.

On systems where H.264 is not available or no HWA, VP9 is preferred. But in Tor
Browser 7.0 all youtube videos are degraded to VP8.

This behaviour can be turned off by setting media.benchmark.vp9.threshold to 0.
All clients will get better experience and lower traffic, beause TBB doesn't
use "Use hardware acceleration when available".

believed were still valid for 102, and some brief description for the
reasons to keep them.

fixup! Firefox preference overrides.

Bug 41043: Hardcode the UI font on Linux

The mechanism to choose the UI font does not play well with our
fontconfig configuration. As a result, the final criterion to choose
the font for the UI was its version.

Since we hardcode Arimo as a default sans-serif on preferences, we use
it also for the UI. FontConfig will fall back to some other font for
scripts Arimo does not cover as expected (we tested with Japanese).

Bug 41901: Hardcode normalized FontSubstitutes.

Windows has a system to set font aliases through the registry.
This allows some customization that could be used as a fingerprinting
vector.
Moreover, this mechanism is used by Windows itself, and different SKUs
might have different default FontSubstitutes.

Bug 30605: Honor privacy.spoof_english in Android

This checks `privacy.spoof_english` whenever `setLocales` is
called from Fenix side and sets `intl.accept_languages`
accordingly.

Bug 40198: Expose privacy.spoof_english pref in GeckoView

Bug 42562: Normalized the Accepted Languages on Android.

The OS language might be outside the list of actually supported
languages and it might leak the user's region.
Therefore, we force the locale reported in Accept-Language to match one
we support with translations, even when it means using a not exact
region tag.

Bug 40171: Make WebRequest and GeckoWebExecutor First-Party aware

Bug 26345: Hide tracking protection UI

Bug 9173: Change the default Firefox profile directory to be relative.

This commit makes Firefox look for the default profile directory in a
directory relative to the binary path.
The directory can be specified through the --with-relative-data-dir.
This is relative to the same directory as the firefox main binary for
Linux and Windows.

On macOS, we remove Contents/MacOS from it.
Or, in other words, the directory is relative to the application
bundle.

This behavior can be overriden at runtime, by placing a file called
system-install adjacent to the firefox main binary (also on macOS).

Bug 13028: Prevent potential proxy bypass cases.

It looks like these cases should only be invoked in the NSS command line
tools, and not the browser, but I decided to patch them anyway because there
literally is a maze of network function pointers being passed around, and it's
very hard to tell if some random code might not pass in the proper proxied
versions of the networking code here by accident.

Base Browser strings

This commit adds all the strings needed by following Base Browser
patches.

Bug 41369: Improve Firefox language settings for multi-lingual packages

Change the language selector to be sorted by language code, rather than
name, and to display the language code to the user.

Bug 41372: Handle Japanese as a special case in preferences on macOS

Japanese is treated in a special way on macOS. However, seeing the
Japanese language tag could be confusing for users, and moreover the
language name is not localized correctly like other langs.

Bug 41378: Tell users that they can change their language at the first start

With multi-lingual builds, Tor Browser matches the user's system
language, but some users might want to change it.
So, we tell them that it is possible, but only once.

Bug 40283: Workaround for the file upload bug

Bug 18905: Hide unwanted items from help menu

Bug 25660: Remove the "New Private Window" option

Bug 31575: Disable Firefox Home (Activity Stream)

Avoid loading AboutNewTab in BrowserGlue.sys.mjs in order
to avoid several network requests that we do not need.

Bug 41624: Disable about:pocket-* pages.

Bug 4234: Use the Firefox Update Process for Base Browser.

Windows: disable "runas" code path in updater (15201).
Windows: avoid writing to the registry (16236).
Also includes fixes for tickets 13047, 13301, 13356, 13594, 15406,
  16014, 16909, 24476, and 25909.

Also fix bug 27221: purge the startup cache if the Base Browser
version changed (even if the Firefox version and build ID did
not change), e.g., after a minor Base Browser update.

Also fix 32616: Disable GetSecureOutputDirectoryPath() functionality.

Bug 26048: potentially confusing "restart to update" message

Within the update doorhanger, remove the misleading message that mentions
that windows will be restored after an update is applied, and replace the
"Restart and Restore" button label with an existing
"Restart to update Tor Browser" string.

Bug 28885: notify users that update is downloading

Add a "Downloading Base Browser update" item which appears in the
hamburger (app) menu while the update service is downloading a MAR
file. Before this change, the browser did not indicate to the user
that an update was in progress, which is especially confusing in
Tor Browser because downloads often take some time. If the user
clicks on the new menu item, the about dialog is opened to allow
the user to see download progress.

As part of this fix, the update service was changed to always show
update-related messages in the hamburger menu, even if the update
was started in the foreground via the about dialog or via the
"Check for Tor Browser Update" toolbar menu item. This change is
consistent with the Tor Browser goal of making sure users are
informed about the update process.

Removed #28885 parts of this patch which have been uplifted to Firefox.

fixup! Bug 4234: Use the Firefox Update Process for Base Browser.

Bug 42747: Discard unsupported updates earlier.

Firefox's updater has a function to select updates, which checks mainly
the version number.
Therefore, a more recent update that is unsupported will be chosen over
a compatible one.
We patch this to be able to provide an alternative update path to
Windows 7.

Bug 42061: Create an alpha update channel.

Bug 41682: Add base-browser nightly mar signing key

Bug 41603: Customize the creation of MOZ_SOURCE_URL

MOZ_SOURCE_URL is created by combining MOZ_SOURCE_REPO and
MOZ_SOURCE_CHANGESET.
But the code takes for granted that it refers to a Hg instance, so it
combines them as `$MOZ_SOURCE_REPO/rev/$MOZ_SOURCE_CHANGESET`.
With this commit, we change this logic to combine them to create a URL
that is valid for GitLab.
$MOZ_SOURCE_CHANGESET needs to be a commit hash, not a branch or a tag.
If that is needed, we could use /-/tree/, instead of /-/commit/.

Bug 41698: Reword the recommendation badges in about:addons

Firefox strings use { -brand-product-name }.
As a result, it seems that the fork is recommending extensions, whereas
AMO curators are doing that.
So, we replace the strings with custom ones that clarify that Mozilla is
recommending them.

We assign the strings with JS because our translation backend does not
support Fluent attributes, yet, but once it does, we should switch to
them, instead.

Bug 42438: Tweaks to the migration wizard.

Remove the items not compatible with our features (such as history) from
the migration wizard.

On Linux, allow to specify an alternative home directory, since we
usually change $HOME in our startup script.

Bug 40069: Add helpers for message passing with extensions

Bug 41598: Prevent NoScript from being removed/disabled.

Bug 40253: Explicitly allow NoScript in Private Browsing mode.

Bug 41736: Hide NoScript extension's toolbar button by default.

This hides it from both the toolbar and the unified extensions panel.

We also hide the unified-extension-button if the panel would be empty:
not including the NoScript button when it is hidden. As a result, this
will be hidden by default until a user installs another extension (or
shows the NoScript button and unpins it).

Bug 41834: Hide "Can't Be Removed - learn more" menu line for uninstallable add-ons

Bug 40925: Implemented the Security Level component

This component adds a new Security Level toolbar button which visually
indicates the current global security level via icon (as defined by the
extensions.torbutton.security_slider pref), a drop-down hanger with a
short description of the current security level, and a new section in
the about:preferences#privacy page where users can change their current
security level. In addition, the hanger and the preferences page will
show a visual warning when the user has modified prefs associated with
the security level and provide a one-click 'Restore Defaults' button to
get the user back on recommended settings.

Bug 40125: Expose Security Level pref in GeckoView

Bug 40926: Implemented the New Identity feature

User-Agent header, to see if matching header and JS property improve
usability.
