Description of problem:

Newly created firefox profiles, no longer copy files from /usr/lib64/firefox/browser/defaults/profile.

Version-Release number of selected component (if applicable):

working with firefox-45.7.0-2.el7_3 but fails with firefox-52.1.0-2.el7_3 and above.

Steps to Reproduce:

1) As user a 'usera' create a blank firefox profile by wiping out the .mozilla directory.

2) As user a 'usera' start firefox

3) Created some bookmarks
=> this should create an places.sqlite file under the newly created .mozilla directory.

4) As root copy this file to /usr/lib64/firefox/browser/defaults/profile

5) As root under /usr/lib64/firefox/browser/defaults/profile/ directory create a file with name xulstore.json with following contents

{"chrome://browser/content/browser.xul":{"navigator-toolbox":{"iconsize":"small"},"PersonalToolbar":{"collapsed":"false"}}}

6) As userb create a blank firefox profile by wiping out the .mozilla directory

7) As userb start firefox.

=> Userb should now have the same bookmarks as those created under usera.  The bookmarks should also be visible.



Actual results:

userb is not getting same bookmarks. 


Expected results:

Userb should now have the same bookmarks as those created under usera.  The bookmarks should also be visible.
