This is technically an embargoed Mozilla bug, so I probably shouldn't provide
too many details.

Suffice to say that NTLM and Negotiate auth are bad for Tor users, and I doubt
very many (or any of them) actually need it.

The Mozilla bug is https://bugzilla.mozilla.org/show_bug.cgi?id=1046421

We cannot use the @mozilla.org/extensions/blocklist;1 service, because we
actually want to stop plugins from ever entering the browser's process space
and/or executing code (for example, AV plugins that collect statistics/analyse
urls, magical toolbars that phone home or "help" the user, skype buttons that
ruin our day, and censorship filters). Hence we rolled our own.

See https://trac.torproject.org/projects/tor/ticket/3547#comment:6 for musings
on a better way. Until then, it is delta-darwinism for us.

Because of the non-restartless nature of Torbutton, it required
a two-stage installation process. On mobile, it was a problem,
because it was not loading when the user opened the browser for
the first time.

Moving it to tor-browser and making it a system extension allows it
to load when the user opens the browser for first time.

Additionally, this patch also fixes Bug 27611.

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The pref "security.enable_tls_session_tickets" is obsolete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.

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".

Under unknown circumstances, we can end up running chrome
JS during thread manager shutdown. Sometimes this ends up
trying to load new JSMs, but gJarHandler has already been
cleared, leading to a crash.

To avoid this and other issues, this patch forbids the
importing of new JSMs after we're late enough in shutdown
to have cleared the ClearOnShutdown pointers. I allow the
importing of JSMs that have already been loaded, as that
seems like it should be okay.
