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.

AT_EMPTY_PATH comes with glibc 2.14. However, Debian Wheezy, which we still use for building our stable Linux bundles, comes only with glibc 2.13 resulting in an "undeclared-identifier"-error during build time.

This problem got introduced by fixing https://bugzilla.mozilla.org/show_bug.cgi?id=1660901.

This loads HTTPS Everywhere as a builtin addon from a hardcoded resource:// URI in desktop. It also ensures that the non-builtin HTTPS Everywhere addon is always uninstalled on browser startup.

The reason of making this desktop-only is that there are some issues when installing a builtin extension from geckoview side, making the extension not available on first startup. So, at least for now we handle the Fenix case separately. See #40118 for a followup for investigating these.

Firefox Pioneer is an opt-in program in which people volunteer to participate in studies that collect detailed, sensitive data about how they use their browser.

In https://bugzilla.mozilla.org/show_bug.cgi?id=1563246 Firefox implemented fetching the Public Suffix List via RemoteSettings and replacing the default one at runtime, which we do not want.

Whenever a valid Onion-Location HTTP header (or corresponding HTML <meta> http-equiv attribute) is found in a document load, we either redirect to it (if the user opted-in via preference) or notify the presence of an onionsite alternative with a badge in the urlbar.

A custom HTTPS Everywhere update channel is installed, which provides rules for locally redirecting some memorable .tor.onion URLs to non-memorable .onion URLs.

When these redirects occur, we also rewrite the URL in the urlbar to display the human-memorable hostname instead of the actual .onion.

It's time for our rotation again: Move the backup key in the front position and add a new backup key.

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.

Do not ship JSON dumps for collections we do not expect to need.

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.

This patch adds a new about:preferences#tor page which allows modifying bridge, proxy, and firewall settings from within Tor Browser. All of the functionality present in tor-launcher's Network Configuration panel is present:

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.

Only ship the pdfjs extension.

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.

notify users that update is downloadingBug 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).

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.

Unless the -osint command line flag is used, the browser now defaults to the equivalent of -no-remote. There is a new -allow-remote flag that may be used to restore the original (Firefox-like) default behavior.

When handling an external URI or downloading a file, invoke Torbutton's external app blocker component (which will present a download warning dialog unless the user has checked the "Automatically download files from now on" box).

For e10s compatibility, avoid using a modal dialog and instead use a callback interface (nsIHelperAppWarningLauncher) to allow Torbutton to indicate the user's desire to cancel or continue each request.

This should eliminate our need to rely on a wrapper script that sets /Users/arthur and launches Firefox with -profile.

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.

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.

Build and package Tor Launcher as part of the browser (similar to how pdfjs is handled).

If a Tor Launcher extension is present in the user's profile, it is removed.

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.

Windows Jump Lists fail for Tor BrowserBug 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.

Firefox downgrades VP9 videos to VP8 when measured performance is not enoughBug 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".
