[tor-browser/tor-browser-89.0-10.5-1] Bug 40091: Load HTTPS Everywhere as a builtin addon in desktop
by sysrqb＠torproject.org 26 May '21

26 May '21

commit 2c4a9093bb460dc8a4ba9abe8e16514b76e26669 Author: Alex Catarineu <acat(a)torproject.org> Date: Fri Sep 4 12:34:35 2020 +0200 Bug 40091: Load HTTPS Everywhere as a builtin addon in desktop This loads HTTPS Everywhere as a builtin addon from a hardcoded resource:// URI in desktop. It also ensures that the non-builtin HTTPS Everywhere addon is always uninstalled on browser startup. The reason of making this desktop-only is that there are some issues when installing a builtin extension from geckoview side, making the extension not available on first startup. So, at least for now we handle the Fenix case separately. See #40118 for a followup for investigating these. --- browser/components/BrowserGlue.jsm | 37 ++++++++++++++++++++++ toolkit/components/extensions/Extension.jsm | 10 ++++-- .../mozapps/extensions/internal/XPIProvider.jsm | 13 ++++++++ 3 files changed, 57 insertions(+), 3 deletions(-) diff --git a/browser/components/BrowserGlue.jsm b/browser/components/BrowserGlue.jsm index bf14d06f9c1d..cac1f2e0a8c4 100644 --- a/browser/components/BrowserGlue.jsm +++ b/browser/components/BrowserGlue.jsm @@ -43,6 +43,7 @@ XPCOMUtils.defineLazyModuleGetters(this, { DownloadsViewableInternally: "resource:///modules/DownloadsViewableInternally.jsm", E10SUtils: "resource://gre/modules/E10SUtils.jsm", + ExtensionData: "resource://gre/modules/Extension.jsm", ExtensionsUI: "resource:///modules/ExtensionsUI.jsm", FeatureGate: "resource://featuregates/FeatureGate.jsm", FirefoxMonitor: "resource:///modules/FirefoxMonitor.jsm", @@ -118,6 +119,13 @@ XPCOMUtils.defineLazyServiceGetters(this, { PushService: ["@mozilla.org/push/Service;1", "nsIPushService"], }); +XPCOMUtils.defineLazyServiceGetters(this, { + resProto: [ + "@mozilla.org/network/protocol;1?name=resource", + "nsISubstitutingProtocolHandler", + ], +}); + const PREF_PDFJS_ISDEFAULT_CACHE_STATE = "pdfjs.enabledCache.state"; /** @@ -1388,6 +1396,35 @@ BrowserGlue.prototype = { "resource://builtin-themes/alpenglow/" ); + // Install https-everywhere builtin addon if needed. + (async () => { + const HTTPS_EVERYWHERE_ID = "https-everywhere-eff(a)eff.org"; + const HTTPS_EVERYWHERE_BUILTIN_URL = + "resource://torbutton/content/extensions/https-everywhere/"; + // This does something similar as GeckoViewWebExtension.jsm: it tries + // to load the manifest to retrieve the version of the builtin and + // compares it to the currently installed one to see whether we need + // to install or not.
