[Prince Willow]

Package: iceweasel
Version: 30.0~a2+20140321004003-1
Severity: normal

Dear Maintainer,

   * What led up to the situation?
   Upgraded to Iceweasel Aurora 30.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   On the Iceweasel start page, click the Sync option.

   * What was the outcome of this action?
   Nothing.

   * What outcome did you expect instead?
   This should open the Sync dialog; functionality works as expected in upstream Aurora 30.
