commit babb7636b06acb0645be12c2f0a0625713c0bb68 Author: Kathy Brade <brade(a)pearlcrescent.com> Date: Thu Apr 16 17:07:09 2020 -0400 Bug 32418: Allow updates to be disabled via an enterprise policy. Restrict the Enterprise Policies mechanism to only consult a policies.json file (avoiding the Windows Registry and macOS's file system attributes). Add a few disabledByPolicy() checks to the update service to avoid extraneous (and potentially confusing) log messages when updates are disabled by policy. Sample content for distribution/policies.json: { "policies": { "DisableAppUpdate": true } } On Linux, avoid reading policies from /etc/firefox/policies/policies.json --- .../enterprisepolicies/EnterprisePoliciesParent.jsm | 14 ++++++++++++-- toolkit/components/enterprisepolicies/moz.build | 3 +++ 2 files changed, 15 insertions(+), 2 deletions(-) diff --git a/toolkit/components/enterprisepolicies/EnterprisePoliciesParent.jsm b/toolkit/components/enterprisepolicies/EnterprisePoliciesParent.jsm index f5de14798de1..9c702ea3fde8 100644 --- a/toolkit/components/enterprisepolicies/EnterprisePoliciesParent.jsm +++ b/toolkit/components/enterprisepolicies/EnterprisePoliciesParent.jsm @@ -4,6 +4,10 @@ var EXPORTED_SYMBOLS = ["EnterprisePoliciesManager"]; +// To ensure that policies intended for Firefox or another browser will not +// be used, Tor Browser only looks for policies in ${InstallDir}/distribution +#define AVOID_SYSTEM_POLICIES MOZ_PROXY_BYPASS_PROTECTION + const { XPCOMUtils } = ChromeUtils.import( "resource://gre/modules/XPCOMUtils.jsm" ); @@ -13,9 +17,11 @@ const { AppConstants } = ChromeUtils.import( ); XPCOMUtils.defineLazyModuleGetters(this, { +#ifndef AVOID_SYSTEM_POLICIES WindowsGPOParser: "resource://gre/modules/policies/WindowsGPOParser.jsm", macOSPoliciesParser: "resource://gre/modules/policies/macOSPoliciesParser.jsm", +#endif Policies: "resource:///modules/policies/Policies.jsm", JsonSchemaValidator: "resource://gre/modules/components-utils/JsonSchemaValidator.jsm", @@ -140,11 +146,13 @@ EnterprisePoliciesManager.prototype = { _chooseProvider() { let platformProvider = null; +#ifndef AVOID_SYSTEM_POLICIES if (AppConstants.platform == "win") { platformProvider = new WindowsGPOPoliciesProvider(); } else if (AppConstants.platform == "macosx") { platformProvider = new macOSPoliciesProvider(); } +#endif let jsonProvider = new JSONPoliciesProvider(); if (platformProvider && platformProvider.hasPolicies) { if (jsonProvider.hasPolicies) { @@ -491,7 +499,7 @@ class JSONPoliciesProvider { _getConfigurationFile() { let configFile = null; - +#ifndef AVOID_SYSTEM_POLICIES if (AppConstants.platform == "linux") { let systemConfigFile = Cc["@mozilla.org/file/local;1"].createInstance( Ci.nsIFile @@ -504,7 +512,7 @@ class JSONPoliciesProvider { return systemConfigFile; } } - +#endif try { let perUserPath = Services.prefs.getBoolPref(PREF_PER_USER_DIR, false); if (perUserPath) { @@ -585,6 +593,7 @@ class JSONPoliciesProvider { } } +#ifndef AVOID_SYSTEM_POLICIES class WindowsGPOPoliciesProvider { constructor() { this._policies = null; @@ -686,3 +695,4 @@ class CombinedProvider { return false; } } +#endif diff --git a/toolkit/components/enterprisepolicies/moz.build b/toolkit/components/enterprisepolicies/moz.build index 09d2046e1bd7..3f685d3fbbd6 100644 --- a/toolkit/components/enterprisepolicies/moz.build +++ b/toolkit/components/enterprisepolicies/moz.build @@ -19,6 +19,9 @@ if CONFIG["MOZ_WIDGET_TOOLKIT"] != "android": EXTRA_JS_MODULES += [ "EnterprisePolicies.jsm", "EnterprisePoliciesContent.jsm", + ] + + EXTRA_PP_JS_MODULES += [ "EnterprisePoliciesParent.jsm", ]

[tor-browser/tor-browser-91.5.0esr-11.5-2] Bug 9173: Change the default Firefox profile directory to be TBB-relative.

commit 17e615981256302ae70f0d6e2007ab27d2a93d10 Author: Kathy Brade <brade(a)pearlcrescent.com> Date: Fri Oct 18 15:20:06 2013 -0400 Bug 9173: Change the default Firefox profile directory to be TBB-relative. This should eliminate our need to rely on a wrapper script that sets /Users/arthur and launches Firefox with -profile. Bug 13252: Do not store data in the app bundle When --enable-tor-browser-data-outside-app-dir is enabled, all user data is stored in a directory named TorBrowser-Data which is located next to the application directory. Display an informative error message if the TorBrowser-Data directory cannot be created due to an "access denied" or a "read only volume" error. On Mac OS, add support for the --invisible command line option which is used by the meek-http-helper to avoid showing an icon for the helper browser on the dock. --- toolkit/profile/nsToolkitProfileService.cpp | 5 +- toolkit/xre/nsAppRunner.cpp | 75 +++++++++++--- toolkit/xre/nsConsoleWriter.cpp | 2 +- toolkit/xre/nsXREDirProvider.cpp | 150 ++++++---------------------- toolkit/xre/nsXREDirProvider.h | 22 ++-- xpcom/io/TorFileUtils.cpp | 133 ++++++++++++++++++++++++ xpcom/io/TorFileUtils.h | 32 ++++++ xpcom/io/moz.build | 5 + xpcom/io/nsAppFileLocationProvider.cpp | 98 ++++++------------ 9 files changed, 315 insertions(+), 207 deletions(-) diff --git a/toolkit/profile/nsToolkitProfileService.cpp b/toolkit/profile/nsToolkitProfileService.cpp index b2920c88345d..154806ebbccf 100644 --- a/toolkit/profile/nsToolkitProfileService.cpp +++ b/toolkit/profile/nsToolkitProfileService.cpp @@ -819,10 +819,11 @@ nsresult nsToolkitProfileService::Init() { NS_ASSERTION(gDirServiceProvider, "No dirserviceprovider!");

by richard＠torproject.org 01 Feb '22

commit a5541e23d8b510a7d5a4af56df8647ca1c277f99 Author: Igor Oliveira <igor.oliveira(a)posteo.net> Date: Sun Dec 10 18:16:59 2017 -0200 Bug 23104: Add a default line height compensation 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. --- layout/generic/ReflowInput.cpp | 19 +++++++++--- layout/generic/test/mochitest.ini | 1 + layout/generic/test/test_tor_bug23104.html | 50 ++++++++++++++++++++++++++++++ 3 files changed, 65 insertions(+), 5 deletions(-) diff --git a/layout/generic/ReflowInput.cpp b/layout/generic/ReflowInput.cpp index 2c56afd2e02a..4d30c7762c14 100644 --- a/layout/generic/ReflowInput.cpp +++ b/layout/generic/ReflowInput.cpp @@ -31,6 +31,7 @@ #include "mozilla/SVGUtils.h" #include "mozilla/dom/HTMLInputElement.h" #include "nsGridContainerFrame.h" +#include "nsContentUtils.h" using namespace mozilla; using namespace mozilla::css; @@ -2642,7 +2643,8 @@ void ReflowInput::CalculateBlockSideMargins() { // For risk management, we use preference to control the behavior, and // eNoExternalLeading is the old behavior. -static nscoord GetNormalLineHeight(nsFontMetrics* aFontMetrics) { +static nscoord GetNormalLineHeight(nsIContent* aContent, + nsFontMetrics* aFontMetrics) { MOZ_ASSERT(nullptr != aFontMetrics, "no font metrics"); nscoord normalLineHeight; @@ -2650,6 +2652,12 @@ static nscoord GetNormalLineHeight(nsFontMetrics* aFontMetrics) { nscoord externalLeading = aFontMetrics->ExternalLeading(); nscoord internalLeading = aFontMetrics->InternalLeading(); nscoord emHeight = aFontMetrics->EmHeight(); + + if (nsContentUtils::ShouldResistFingerprinting() && + !aContent->IsInChromeDocument()) { + return NSToCoordRound(emHeight * NORMAL_LINE_HEIGHT_FACTOR); + } + switch (GetNormalLineHeightCalcControl()) { case eIncludeExternalLeading: normalLineHeight = emHeight + internalLeading + externalLeading; @@ -2667,7 +2675,8 @@ static nscoord GetNormalLineHeight(nsFontMetrics* aFontMetrics) { return normalLineHeight; } -static inline nscoord ComputeLineHeight(ComputedStyle* aComputedStyle, +static inline nscoord ComputeLineHeight(nsIContent* aContent, + ComputedStyle* aComputedStyle, nsPresContext* aPresContext, nscoord aBlockBSize, float aFontSizeInflation) { @@ -2696,7 +2705,7 @@ static inline nscoord ComputeLineHeight(ComputedStyle* aComputedStyle, RefPtr<nsFontMetrics> fm = nsLayoutUtils::GetFontMetricsForComputedStyle( aComputedStyle, aPresContext, aFontSizeInflation); - return GetNormalLineHeight(fm); + return GetNormalLineHeight(aContent, fm); } nscoord ReflowInput::CalcLineHeight() const { @@ -2718,7 +2727,7 @@ nscoord ReflowInput::CalcLineHeight(nsIContent* aContent, float aFontSizeInflation) { MOZ_ASSERT(aComputedStyle, "Must have a ComputedStyle"); - nscoord lineHeight = ComputeLineHeight(aComputedStyle, aPresContext, + nscoord lineHeight = ComputeLineHeight(aContent, aComputedStyle, aPresContext, aBlockBSize, aFontSizeInflation); NS_ASSERTION(lineHeight >= 0, "ComputeLineHeight screwed up"); @@ -2731,7 +2740,7 @@ nscoord ReflowInput::CalcLineHeight(nsIContent* aContent, if (!lh.IsNormal()) { RefPtr<nsFontMetrics> fm = nsLayoutUtils::GetFontMetricsForComputedStyle( aComputedStyle, aPresContext, aFontSizeInflation); - nscoord normal = GetNormalLineHeight(fm); + nscoord normal = GetNormalLineHeight(aContent, fm); if (lineHeight < normal) { lineHeight = normal; } diff --git a/layout/generic/test/mochitest.ini b/layout/generic/test/mochitest.ini index bde689457ebc..af9dbe3c0444 100644 --- a/layout/generic/test/mochitest.ini +++ b/layout/generic/test/mochitest.ini @@ -145,3 +145,4 @@ skip-if = debug == true || tsan # the test is slow. tsan: bug 1612707 support-files = file_reframe_for_lazy_load_image.html [test_bug1655135.html] +[test_tor_bug23104.html] diff --git a/layout/generic/test/test_tor_bug23104.html b/layout/generic/test/test_tor_bug23104.html new file mode 100644 index 000000000000..8ff1d2190c45 --- /dev/null +++ b/layout/generic/test/test_tor_bug23104.html @@ -0,0 +1,50 @@ +<!DOCTYPE HTML> +<meta charset="UTF-8"> +<html> +<head> + <title>Test for Tor Bug #23104: CSS line-height reveals the platform Tor browser is running</title> + <script type="application/javascript" src="/tests/SimpleTest/SimpleTest.js"></script> + <script type="application/javascript" src="/tests/SimpleTest/SpawnTask.js"></script> + <style type="text/css"> + span { + background-color: #000; + color: #fff; + font-size: 16.5px; + } + </style> +</head> +<body> +<span id="test1">Test1</span> +<span id="test2">كلمة</span> +<span id="test3">ação</span> +<script> + +let setPref = async function (key, value) { + await SpecialPowers.pushPrefEnv({"set": [[key, value]]}); +} + +function getStyle(el, styleprop) { + el = document.getElementById(el); + return document.defaultView.getComputedStyle(el, null).getPropertyValue(styleprop); +} + +function validateElement(elementName, isFingerprintResistent) { + var fontSize = getStyle(elementName, 'font-size'); + var lineHeight = getStyle(elementName, 'line-height'); + var validationCb = isFingerprintResistent ?

[tor-browser/tor-browser-91.5.0esr-11.5-2] Bug 32220: Improve the letterboxing experience

01 Feb '22

commit d54491873d7e1d27ccb37ad457131f4f99f8aff0 Author: Richard Pospesel <richard(a)torproject.org> Date: Mon Oct 28 17:42:17 2019 -0700 Bug 32220: Improve the letterboxing experience CSS and JS changes to alter the UX surrounding letterboxing. The browser element containing page content is now anchored to the bottom of the toolbar, and the remaining letterbox margin is the same color as the firefox chrome. The letterbox margin and border are tied to the currently selected theme. Also adds a 'needsLetterbox' property to tabbrowser.xml to fix a race condition present when using the 'isEmpty' property. Using 'isEmpty' as a proxy for 'needsLetterbox' resulted in over-zealous/unnecessary letterboxing of about:blank tabs. --- browser/base/content/browser.css | 7 ++ browser/base/content/tabbrowser-tab.js | 9 +++ browser/themes/shared/tabs.inc.css | 6 ++ .../components/resistfingerprinting/RFPHelper.jsm | 94 +++++++++++++++++++--- 4 files changed, 104 insertions(+), 12 deletions(-) diff --git a/browser/base/content/browser.css b/browser/base/content/browser.css index 2d74162b1543..0a766b976fc5 100644 --- a/browser/base/content/browser.css +++ b/browser/base/content/browser.css @@ -94,6 +94,13 @@ body { } } +.browserStack > browser.letterboxing { + border-color: var(--chrome-content-separator-color); + border-style: solid; + border-width : 1px; + border-top: none; +} + %ifdef MENUBAR_CAN_AUTOHIDE #toolbar-menubar[autohide="true"] { overflow: hidden; diff --git a/browser/base/content/tabbrowser-tab.js b/browser/base/content/tabbrowser-tab.js index 320ca559d5fa..47edf39d9eba 100644 --- a/browser/base/content/tabbrowser-tab.js +++ b/browser/base/content/tabbrowser-tab.js @@ -229,6 +229,15 @@ return true; } + get needsLetterbox() { + let browser = this.linkedBrowser; + if (isBlankPageURL(browser.currentURI.spec)) { + return false; + } + + return true; + } + get lastAccessed() { return this._lastAccessed == Infinity ?
