Hi Paul, with last upload all not-essential ubuntu pref tweaks went intentionally into ubufox extension which is a recommends of firefox and will be installed by ubuntu-desktop soon.
In this way users can still get back to genuine ffox upstream behaviour by disabling this extension Add-Ons dialog. If you still see problems with ubufox installed, please file a bug against ubufox.
