commit bc8af4dcdafd3de656bbff245eb70a0025829b90 Author: Kathy Brade <brade@pearlcrescent.com> Date: Fri Jan 29 16:47:26 2016 -0500 fixup! Bug 16620: Clear window.name when no referrer sent Only clear window.name for the top document, not for frames. This fixes Bug 18168: iframe-based AJAX call opening in new tab and more closely matches the behavior of Torbutton's old JavaScript-based implementation. --- docshell/base/nsDocShell.cpp | 18 +++-- docshell/test/mochitest.ini | 1 + docshell/test/test_tor_bug16620.html | 131 ++++++++++++++++++++++++++++------- docshell/test/tor_bug16620_form.html | 51 ++++++++++++++ 4 files changed, 173 insertions(+), 28 deletions(-) diff --git a/docshell/base/nsDocShell.cpp b/docshell/base/nsDocShell.cpp index 0c404fa..3f059673 100644 --- a/docshell/base/nsDocShell.cpp +++ b/docshell/base/nsDocShell.cpp @@ -8993,8 +8993,9 @@ nsDocShell::CreateContentViewer(const char* aContentType, } FirePageHideNotification(!mSavingOldViewer); - // Tor bug # 16620: Clear window.name if there is no referrer.
