Windows 7/8 and macOS 10.12-10.14 Legacy/MaintenanceBug 42747: Discard unsupported updates earlier.

notify users that update is downloadingBug 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.

This hides it from both the toolbar and the unified extensions panel.

We also hide the unified-extension-button if the panel would be empty: not including the NoScript button when it is hidden. As a result, this will be hidden by default until a user installs another extension (or shows the NoScript button and unpins it).

Downloads button warning no longer announced on OrcaBug 42642: Focus the "Got it" button when opening the downloads panel.

This should ensure that the alert is read aloud by Orca screen reader.

Shown in the downloads panel, about:downloads and places.xhtml.

This patch associates the about:manual page to a translated page that must be injected to browser/omni.ja after the build. The content must be placed in chrome/browser/content/browser/manual/, so that is then available at chrome://browser/content/manual/. We preferred giving absolute freedom to the web team, rather than having to change the patch in case of changes on the documentation.

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.

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.

Several console errors: Console.maxLogLevelPref used with a non-existing pref:Bug 42596: Add preferences for log levels.

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.

TorBrowser might want to have an error page specific to when .onion links failbug 19251: use enhanced error pages for onion service errors.

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.

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.

This commit adds all the strings needed by following Base Browser patches.

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 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).

The OS language might be outside the list of actually supported languages and it might leak the user's region. Therefore, we force the locale reported in Accept-Language to match one we support with translations, even when it means using a not exact region tag.

This checks privacy.spoof_english whenever setLocales is called from Fenix side and sets intl.accept_languages accordingly.

Windows 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.

The pref "security.enable_tls_session_tickets" is obsolete (removed in https://bugzilla.mozilla.org/917049)

Audit HTTP/2 and SPDY if neededBug 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.

Setting general.useragent.override does not spoof the platform part anymore in ESR 60 which is confusingBug 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.

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 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

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.
