High CPU load after tor exits unexpectedlyBug 40501: High CPU load after tor exits unexpectedly

When a peers (tor) disconnects, Firefox seems to keep the stream open, and return 0 on available, rather than throwing. So, as a matter of fact, we had a while trying to read 0 bytes without any pause in _readLine, hence the 100% CPU usage.

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.

Additionally, this patch also fixes AndroidBug
Restart Gecko after first-runBug 27611.

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.

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.

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.

Improve security warning when downloading a fileBug 40701: Improve security warning when downloading a file This reverts commit 5d003f7c5e0910c8e0c6f4e55a0ca7aa002faad1.

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.

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.

Add support for onion services strings to the TorStrings module.

Page Info window for view-source:http://...onion addresses says Connection Not EncryptedBug 41533: Fix onion detection on the page info window

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.

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.

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.

Disable the "Create New Login" button when security.nocertdb is true.

Only ship the pdfjs extension.

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 RESOLVED FIXED(Fx52), Blocks: 1299627, 1299694, 1528884
Remove MOZ_EME build option and make EME disabled by preferences.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.

iis windows authentication prompt not showing uptor-browser#27602

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.

Rebase geckoview patches to 99.0Bug 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.

Prevent mach package-multi-locale from actually creating a packageBug 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.
