Firefox looses all customizations
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0 (Beta/Release) Build ID: 20140212131424 Steps to reproduce: Selected the customize option to change the layout and buttons on the toolbar Actual results: The buttons were as expected on the current Firefox window. But opening a new window gave a button layout that is the same as before the customizations took place. All subsequent windows showed the old button layout. After changing the layout on the new windows the customizations would stay for a short while, but then would be lost again. Expected results: The customizations should remain all the time.
Does it happen in safe mode (https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode)? If it does not, please try disabling extensions to see if any of them is the cause.
