 Priority:  normal        |  Milestone:  Awaiting Review
Component:  General       |    Version:  4.6.1

 Using Wordpress 4.6.1. Works in Chrome. Only works from time to time in
 Firefox:

 Steps to reproduce:

 1. Create new post
 2. Publish post
 3. Modify content and wait for autosaving
 4. Reload page

 Expected result: Restore backup notice including restore backup button
 Actual result: Autosave notice

 After I debugged a little bit, I realized that Firefox is not able to
 delete the cookie 'wp-saving-post' by using wpCookies.remove('wp-saving-
 post'). It seems to work only when you specify the path: wpCookies.remove
 ('wp-saving-post', '/app/wp-admin')
