Bug 1941154 - Use shader to clear alpha targets on Adreno 510. a=diannaS DONTBUILD
Recent refactoring of render target initialization caused stale
contents of alpha render targets to be used as clip masks instead of
valid masks on Adreno 510 devices. Presumably we were fortunate not to
be hitting this previously, and it was regressed by a subtle
accidental behavioural change introduced by the refactor. Using quads
to clear alpha targets appears to be the most robust way of avoiding
it.

BB 42220: Allow for more file types to be forced-inline.
Firefox allows to open some files in the browser without any
confirmation, but this will result in a disk leak, because the file will
be downloaded to the temporary directory first (and not deleted, in some
cases).
A preference allows PDFs to be opened without being downloaded to disk.
So, we introduce a similar one to do the same for all the files that are
set to be opened automatically in the browser, except svg and html files
to prevent XSS hazards (see BB 43211).

Tweaks to the build system
Bug 40857: Modified the fat .aar creation file
This is a workaround to build fat .aars with the compiling enviornment
disabled.
Mozilla does not use a similar configuration, but either runs a Firefox
build and discards its output, or uses artifacts build.
We might switch to artifact builds too, and drop this patch, or write a
better one to upstream. But until then we need this patch.
See also https://bugzilla.mozilla.org/show_bug.cgi?id=1763770.
Bug 41458: Prevent `mach package-multi-locale` from actually creating a package
macOS builds need some files to be moved around with
./mach package-multi-locale to create multi-locale packages.
The required command isn't exposed through any other mach command.
So, we patch package-multi-locale both to prevent it from failing when
doing official builds and to detect any future changes on it.

Even though we disable sync by default with
`identity.fxaccounts.enabled`, this about: page is still avilable.
We could throw an exception on the constructor of the related
component, but it would result only in an error in the console, without
a visible "this address does not look right" error page.
If we fix the issues with MOZ_SERVICES_SYNC, we can restore the
component.

BB 31740: Remove some unnecessary RemoteSettings instances
More concretely, SearchService.jsm 'hijack-blocklists' and
url-classifier-skip-urls.
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.

BB 41599: Always return an empty string as network ID
Firefox computes an internal network ID used to detect network changes
and act consequently (e.g., to improve WebSocket UX).
However, there are a few ways to get this internal network ID, so we
patch them out, to be sure any new code will not be able to use them and
possibly link users.
We also sent a patch to Mozilla to seed the internal network ID, to
prevent any accidental leak in the future.

BB 43140: Tighten up fonts on Linux.
We ship a fontconfig configuration to esnure all Linux users have the
same defaults and reduce the chances of fingerprinting.
We used to add this file in tor-browser-build, but some users might
skip it by using the browser executable without the wrapper script.
Therefore, we decided to activate the file with the FontConfig API
instead of the environment variables.
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).

BB 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).

So, we check if the original home directory is known, and use that,
instead.

very hard to tell if some random code might not pass in the proper proxied
versions of the networking code here by accident.

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

language, but some users might want to change it.
So, we tell them that it is possible, but only once.

BB 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.

BB 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/.

MB 21: Disable the password manager
This commit disables the about:login page and removes the "Login and
Password" section of about:preferences.
We do not do anything to the real password manager of Firefox, that is
in toolkit: it contains C++ parts that make it difficult to actually
prevent it from being built..
Finally, we modify the the function that opens about:login to report an
error in the console so that we can quickly get a backtrace to the code
that tries to use it.
