I do not want to talk to the community of users I want the top dog from Mozilla Firefox to tell me.

1: Why can't you make the new sync an installable update to work with the older versions of Firefox... current version I run is 24.0 ESR... because all my favorite skins and add-ons work.

2: Why do we have to upgrade to the new Firefox, when the older versions have the add-ons and skins most of us love. New Ugly versions of Firefox will not run the the nice older skins, just the worthless themes that are just a color and background image Maybe you can make a wrapper to use older skins on newer versions of this UGLY Browser.

 3: Why should we upgrade just because of a newer sync  when the old one works just fine. and if we do update what is the oldest / lowest version number we can install to meet the new sync requirements  ?? 
 3a:  If we upgrade WHY ! ?? can't we install 2 versions of Firefox, 1 for the sync and 1 older version to use everyday that looks good with our favorite skins and add-ons.   I would waste space on my drive to have 2 versions if the only way sync would work is in the new version...just import bookmarks to new version and never use it only to update my phone bookmarks. 

 4: It seems to me you are letting Google Chrome ( another really UGLY Browser ) over run your own ideas of what a browser should / can be and look like...WHY ??  I can see this from the way the old versions look and run compared to the new junk you have put out since version 27.0.1.

 5: Don't tell me security is the reason for being ugly and the good older skins / add-ons not working, that is why everyone runs Firewalls, Anti-Virus,  Anti-Malware and Windows Defender  software.. to be secure.
