Unsharp Icons in FF 29 Customize Window

[Endor]

Hi Giorgio.

This picture is from the new Customizing Window, this Icons are on the pane on left side.

As you can see, this two icons, are not in the right resolution.
Actually the are in 16 x 16 px, but to look sharp the need to be 32 x 32px
and for hi resolution Monitors the should be 33 x 33px with a empty border of 1px.

Please take a look.
Thanks.
Cheers
Endor
