commit aa38c32e5c4aa1b9ea9b1773fbc9bd51e8365698 Author: Kathy Brade brade@pearlcrescent.com Date: Wed Nov 25 11:36:20 2015 -0500

Bug 16940: After update, load local change notes.

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.

Also fix bug 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. --- browser/actors/AboutTBUpdateChild.jsm | 12 +++ browser/actors/AboutTBUpdateParent.jsm | 120 +++++++++++++++++++++ browser/actors/moz.build | 6 ++ .../base/content/abouttbupdate/aboutTBUpdate.css | 74 +++++++++++++ .../base/content/abouttbupdate/aboutTBUpdate.js | 27 +++++ .../base/content/abouttbupdate/aboutTBUpdate.xhtml | 39 +++++++ browser/base/content/browser-siteIdentity.js | 2 +- browser/base/content/browser.js | 4 + browser/base/jar.mn | 5 + browser/components/BrowserContentHandler.jsm | 55 +++++++--- browser/components/BrowserGlue.jsm | 15 +++ browser/components/about/AboutRedirector.cpp | 6 ++ browser/components/about/components.conf | 3 + browser/components/moz.build | 5 +- .../locales/en-US/chrome/browser/aboutTBUpdate.dtd | 8 ++ browser/locales/jar.mn | 3 + toolkit/modules/RemotePageAccessManager.jsm | 5 + 17 files changed, 373 insertions(+), 16 deletions(-)
