Encrypting pages hosted on Onion Services with SSL/TLS is redundant
(in terms of hiding content) as all traffic within the Tor network is
already fully encrypted.  Therefore, serving HTTP pages from an Onion
Service is more or less fine.

Prior to this patch, Tor Browser would mostly treat pages delivered
via Onion Services as well as pages delivered in the ordinary fashion
over the internet in the same way.  This created some inconsistencies
in behaviour and misinformation presented to the user relating to the
security of pages delivered via Onion Services:

 - HTTP Onion Service pages did not have any 'lock' icon indicating
   the site was secure
 - HTTP Onion Service pages would be marked as unencrypted in the Page
   Info screen
 - Mixed-mode content restrictions did not apply to HTTP Onion Service
   pages embedding Non-Onion HTTP content

This patch fixes the above issues, and also adds several new 'Onion'
icons to the mix to indicate all of the various permutations of Onion
Services hosted HTTP or HTTPS pages with HTTP or HTTPS content.

Strings for Onion Service Page Info page are pulled from Torbutton's
localization strings.

This patch adds a new 'securitylevel' component to Tor Browser intended
to replace the torbutton 'Security Slider'.

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.

Strings used by this patch are pulled from the torbutton extension, but
en-US defaults are provided if there is an error loading from the
extension. With this patch applied, the usual work-flow of "./mach build
&& ./mach run" work as expected, even if the torbutton extension is
disabled.

Many fonts have issues with their vertical metrics. they
are used to influence the height of ascenders and depth
of descenders. Gecko uses it to calculate the line height
(font height + ascender + descender), however because of
that idiosyncratic behavior across multiple operating
systems, it can be used to identify the user's OS.

The solution proposed in the patch uses a default factor
to be multiplied with the font size, simulating the concept
of ascender and descender. This way all operating
systems will have the same line height only and only if the
frame is outside the chrome.

Bug 16322: Update DuckDuckGo search engine

We are replacing the clearnet URL with an onion service one (thanks to a
patch by a cypherpunk) and are removing the duplicated DDG search
engine. Duplicating DDG happend due to bug 1061736 where Mozilla
included DDG itself into Firefox. Interestingly, this caused breaking
the DDG search if JavaScript is disabled as the Mozilla engine, which
gets loaded earlier, does not use the html version of the search page.
Moreover, the Mozilla engine tracked where the users were searching from
by adding a respective parameter to the search query. We got rid of that
feature as well.

Also:
This fixes bug 20809: the DuckDuckGo team has changed its server-side
code in a way that lets users with JavaScript enabled use the default
landing page while those without JavaScript available get redirected
directly to the non-JS page. We adapt the search engine URLs
accordingly.

Also fixes bug 29798 by making sure we only specify the Google search
engine we actually ship an .xml file for.

Configure with --enable-verify-mar (when updating, require a valid
  signature on the MAR file before it is applied).
Use the Tor Browser version instead of the Firefox version inside the
  MAR file info block (necessary to prevent downgrade attacks).
Use NSS on all platforms for checking MAR signatures (instead of using
  OS-native APIs, which Mozilla does on Mac OS and Windows). So that the
  NSS and NSPR libraries the updater depends on can be found at runtime,
  we add the firefox directory to the shared library search path on macOS.
  On Linux, rpath is used by Mozilla to solve that problem, but that
  approach won't work on macOS because the updater executable is copied
  during the update process to a location that is under TorBrowser-Data,
  and the location of TorBrowser-Data varies.

Bug 26048: potentially confusing "restart to update" message

Within the update doorhanger, remove the misleading message that mentions

"Restart and Restore" button label with an existing

Bug 28885: notify users that update is downloading

Add a "Downloading Tor 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.

Use a localized string from Torbutton for the app menu's
"Downloading update" message. This is a temporary fix that can
be removed once Tor Browser is based on Firefox 79 or newer (at
which point the localized string will be included in the Firefox
language packs).

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.)

In Tor Browser 8.0, the OS was revealed in both the HTTP User-Agent

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.
