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.

Improve support for non-portable modeBug 20497: Make it possible to disable portable mode

9173 is the patch that enables portable mode for Tor Browser. We modified it to make it optional, but it still used to remove a few important parts that made it compulsory to define a profile directory in the application.ini (through the mozconfig).

This commit restores these parts, and makes it hopefully possible to disable portable mode without filling the home directory with TBB files. A few parts are then disabled in a following commit, since they are TBB-legacy behavior, but we might not want them for base-browser and for privacy-browser.

Also, this commit changes the configure flag from --with-relative-profile-directory to --with-relative-data-dir, because the data directories can contain the profile and the local data such as caches, not only the profile. Still, we are assuming we are using the same data directory for the profile and for the caches, which is not the case on Windows (where the profile is roaming, and the caches are local) and on Linux (where the profile is in the home, and the cache is in ~/.cache).

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

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.

Inform users when Tor Browser sets their language automaticallyBug 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.

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.

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.

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.

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).

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.

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).

We also clear the collections database on the v2 -> v3 migration.

For now this function only deletes old language packs for which we are already packaging the strings with the application.

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.

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.

eBay and Amazon don't treat Tor users very well. Accounts often get locked and payments reversed.

Add an about:tbupdate page that displays the first section from TorBrowser/Docs/ChangeLog.txt and includes a link to the remote post-update page (typically our blog entry for the release).

Always load about:tbupdate in a content process, but implement the code that reads the file system (changelog) in the chrome process for compatibility with future sandboxing efforts.

Update about:tor when Tor Browser is updatedbug 29440. Now about:tbupdate is styled as a fairly simple changelog page that is designed to be displayed via a link that is on about:tor.

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.
