commit 7c8b836e87bc2e5251ff085d48114d61678544d3 Author: Kathy Brade brade@pearlcrescent.com Date: Wed Feb 3 15:22:12 2016 -0500

Bug 18170: After update, only changelog tab shown

When in permanent private browsing mode, always return false for isAutomaticRestoreEnabled. This ensures that there will not be any confusion inside nsBrowserContentHandler.defaultArgs as to whether a one time session restore will occur.

Also, for consistency and in case someone looks at the pref, avoid setting browser.sessionstore.resume_session = true during browser shutdown.

This bug occurred when staging was not used during the update process. On Windows it always occurred because staging is not used even when it should be (see #18292). --- browser/components/nsBrowserGlue.js | 4 +++- browser/components/sessionstore/SessionStore.jsm | 5 ++++- browser/components/sessionstore/nsSessionStartup.js | 4 ++++ 3 files changed, 11 insertions(+), 2 deletions(-)
