    BB 43072: Add aria label and description to moz-message-bar.

Ensures that moz-message-bar, including notifications, are announced on
Orca.

This addresses upstream bugzilla bug 1895857 and should likely be
replaced when it is fixed.

    BB 42739: Use the brand name for profile error messages.

Some messages in profileSelection.properties use gAppData->name as
variable inputs. However, gAppData->name is still "Firefox" for our
base-browser builds, rather than the user-facing browser name. We swap
these instances with the displayed brand name instead.

    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).

The currently vendored copy of python-attrs's .git_archival.txt
includes a ref-names field which might make source tarballs not
reproducible.
Upstream fixed this in da2333cd37747d692d5c78b0c94bd400ff883a9a,
therefore we apply the same change until Mozilla vendors an updated
copy of python-attrs.

    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.

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.

In the past the ClearKey system had not been compiled when specifying

case for it is not really visible while the code had security
vulnerabilities in the past.

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).

In Bug 93141, Mozilla started sending users to their home when they type

On Linux, we change $HOME for various reason, therefore you would be
redirected to the spoofed home directory when typing ~.
So, we check if the original home directory is known, and use that,
instead.

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.

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.

  16014, 16909, 24476, and 25909.

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.

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/.

    TB 2176: Rebrand Firefox to TorBrowser

See also Bugs #5194, #7187, #8115, #8219.

This patch does some basic renaming of Firefox to TorBrowser. The rest of the
branding is done by images and icons.

Also fix bug 27905.

Bug 25702: Update Tor Browser icon to follow design guidelines

- Updated all of the branding in /browser/branding/official with new 'stable'
icon series.
- Updated /extensions/onboarding/content/img/tor-watermark.png with new icon and
add the source svg in the same directory
- Copied /browser/branding/official over /browser/branding/nightly and the new
/browser/branding/alpha directories. Replaced content with 'nightly' and
'alpha' icon series.
Updated VisualElements_70.png and VisualElements_150.png with updated icons in
each branding directory (fixes #22654)
- Updated firefox.VisualElementsManfiest.xml with updated colors in each
branding directory
- Added firefox.svg to each branding directory from which all the other icons
are derived (apart from document.icns and document.ico)
- Added default256.png and default512.png icons
- Updated aboutTBUpdate.css to point to branding-aware icon128.png and removed
original icon
- Use the Tor Browser icon within devtools/client/themes/images/.

Bug 30631: Blurry Tor Browser icon on macOS app switcher

It would seem the png2icns tool does not generate correct icns files and
so on macOS the larger icons were missing resulting in blurry icons in
the OS chrome. Regenerated the padded icons in a macOS VM using
iconutil.

Bug 28196: preparations for using torbutton tor-browser-brand.ftl

A small change to Fluent FileSource class is required so that we
can register a new source without its supported locales being
counted as available locales for the browser.

Bug 31803: Replaced about:debugging logo with flat version

Bug 21724: Make Firefox and Tor Browser distinct macOS apps

When macOS opens a document or selects a default browser, it sometimes
uses the CFBundleSignature. Changing from the Firefox MOZB signature to
a different signature TORB allows macOS to distinguish between Firefox
and Tor Browser.

Bug 32092: Fix Tor Browser Support link in preferences

about:tor needs these files but it is included earlier.

Before reordering patches, we used to keep the Tor-related patches

After that issue, we decided to move them towards the end.

In addition to that, we have decided to move Tor Browser-only
preferences there, too, to make Base Browser-only fixups easier to
apply.

    TB 23247: Communicating security expectations for .onion

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.

    by Kathy Brade at 2026-02-18T17:16:39-08:00 
    TB 30237: Add v3 onion services client authentication prompt

When Tor informs the browser that client authentication is needed,
temporarily load about:blank instead of about:neterror and prompt
for the user's key.

If a correctly formatted key is entered, use Tor's ONION_CLIENT_AUTH_ADD
control port command to add the key (via Torbutton's control port
module) and reload the page.

If the user cancels the prompt, display the standard about:neterror
"Unable to connect" page. This requires a small change to
browser/actors/NetErrorChild.jsm to account for the fact that the
docShell no longer has the failedChannel information. The failedChannel
is used to extract TLS-related error info, which is not applicable
in the case of a canceled .onion authentication prompt.

Add a leaveOpen option to PopupNotifications.show so we can display
error messages within the popup notification doorhanger without
closing the prompt.

Add support for onion services strings to the TorStrings module.

Add support for Tor extended SOCKS errors (Tor proposal 304) to the
socket transport and SOCKS layers. Improved display of all of these
errors will be implemented as part of bug 30025.

Also fixes bug 19757:
 Add a "Remember this key" checkbox to the client auth prompt.

 Add an "Onion Services Authentication" section within the
 about:preferences "Privacy & Security section" to allow
 viewing and removal of v3 onion client auth keys that have
 been stored on disk.

Also fixes bug 19251: use enhanced error pages for onion service errors.

Whenever a valid Onion-Location HTTP header (or corresponding HTML

presence of an onionsite alternative with a badge in the urlbar.

We have enabled HTTPS-Only mode, therefore we do not need
HTTPS-Everywhere anymore.
However, we want to keep supporting .tor.onion aliases (especially for
securedrop).
Therefore, in this patch we implemented the parsing of HTTPS-Everywhere
rulesets, and the redirect of .tor.onion domains.
Actually, Tor Browser believes they are actual domains. We change them
on the fly on the SOCKS proxy requests to resolve the domain, and on
the code that verifies HTTPS certificates.

that is then available at chrome://browser/content/manual/.

    TB 41197: [android] Disable autofill.

Firefox is an Autofill service. From the Android docs:

> An autofill service is an app that makes it easier for users to fil
> out forms by injecting data into the views of other apps. Autofill
> services can also retrieve user data from the views in an app and
> store it for use at a later time. Autofill services are usually
> provided by apps that manage user data, such as password managers.

Tor Browser is not an autofill service. All of the autofill backend
is disabled at build time, since it lives in application-services.

This commit disabled the client side of autofill.

Undo rebase mistake. An unrelated pref was accidentally
disabled in this commit. We do want it disabled, it's just
unrelated here.

Will remove it from here and then add it to another commit.
