Pier Angelo Vendrame authoredWindows has a system to set font aliases through the registry. This allows some customization that could be used as a fingerprinting vector. Moreover, this mechanism is used by Windows itself, and different SKUs might have different default FontSubstitutes.

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).

This hack directly includes our preference changes in omni.ja. Bug 18292: Staged updates fail on Windows Temporarily disable staged updates on Windows. Bug 18297: Use separate Noto JP,KR,SC,TC fonts Bug 23404: Add Noto Sans Buginese to the macOS whitelist Bug 23745: Set dom.indexedDB.enabled = true Bug 13575: Disable randomised Firefox HTTP cache decay user tests. (Fernando Fernandez Mancera <ffmancera@riseup.net>) 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 The pref "security.enable_tls_session_tickets" is obsolete (removed in https://bugzilla.mozilla.org/917049) Bug 14952: Enable http/2 and AltSvc In Firefox, SPDY/HTTP2 now uses Origin Attributes for isolation of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. "network.http.sped.enabled.v3-1" was removed in Bug 1248197. Bug 26114: addons.mozilla.org is not special * Don't expose navigator.mozAddonManager on any site * Don't block NoScript from modifying addons.mozilla.org or other sites Enable ReaderView mode again (#27281). Bug 29916: Make sure enterprise policies are disabled Bug 2874: Block Components.interfaces from content 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 30845: Make sure default themes and other internal extensions are enabled Bug 28896: Enable extensions in private browsing by default Bug 31065: Explicitly allow proxying localhost Bug 31598: Enable letterboxing Disable Presentation API everywhere Bug 21549 - Use Firefox's WASM default pref. It is disabled at safer security levels. Bug 32321: Disable Mozilla's MitM pings Bug 19890: Disable installation of system addons By setting the URL to "" we make sure that already installed system addons get deleted as well. 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". Bug 25741 - TBA: Add mobile-override of 000-tor-browser prefs Bug 16441: Suppress "Reset Tor Browser" prompt. Bug 29120: Use the in-memory media cache and increase its maximum size.

See the description of that issue to see all the preferences we believed were still valid for 102, and some brief description for the reasons to keep them.

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. Upstream: https://bugzilla.mozilla.org/show_bug.cgi?id=1817756

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.

Firefox Ion (previously 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. Bug 41662: Disable about:sync-logs 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.

In the past the ClearKey system had not been compiled when specifying --disable-eme. But that changed and it is even bundled nowadays (see: Mozilla's bug 1300654). We don't want to ship it right now as the use case for it is not really visible while the code had security vulnerabilities in the past.

The GeckoView AndroidManifest.xml is not preprocessed unlike Fennec's manifest, so we can't use the ifdef preprocessor guards around the permissions we do not want. Commenting the permissions is the next-best-thing.

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.
