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

The URL query stripping service is enabled only in nightly builds,
still it is initialized and remote settings are downloaded.
This adds a condition that prevents the service from being initialized
if disabled.

We should remove this patch if Mozilla decides that this is a problem
also for them, or if they do not but we decide to use the feature.

Bug 25660: Remove the "New Private Window" option

cypherpunks1 authored 2 years ago and Pier Angelo Vendrame committed 2 years ago

(cherry picked from commit 1bacd26d)

This is a temporary patch that we need until we switch our strings to
Fluent. The reason is that we currently set strings when we populate
our XUL content.
We could rework the whole mechanism, but it is not worth it because we
want to switch to Fluent, which will handle everything automatically.

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 41434: Letterboxing, preemptively apply margins in a global CSS rule to mitigate race conditions on newly created windows and tabs.

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 17252: Enable session identifiers with FPI

Session tickets and session identifiers were isolated
by OriginAttributes, so we can re-enable them by
allowing the default value (true) of
"security.ssl.disable_session_identifiers".

The pref "security.enable_tls_session_tickets" is obsolete
(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.

"network.http.spdy.enabled.http2draft" was removed in Bug 1132357.
"network.http.sped.enabled.v2" was removed in Bug 912550.
"network.http.sped.enabled.v3" was removed in Bug 1097944.
"network.http.sped.enabled.v3-1" was removed in Bug 1248197.

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".

More concretely, SearchService.jsm 'hijack-blocklists' and

Avoid creating instance for 'anti-tracking-url-decoration'.

If prefs are disabling their usage, avoid creating instances for
'cert-revocations' and 'intermediates'.

Do not ship JSON dumps for collections we do not expect to need. For
the ones in the 'main' bucket, this prevents them from being synced
unnecessarily (the code in remote-settings does so for collections
in the main bucket for which a dump or local data exists). For the
collections in the other buckets, we just save some size by not
shipping their dumps.

We also clear the collections database on the v2 -> v3 migration.
