MultiRowTabLiteforFx.uc.js affects Firefox print page setup

[Benuzar]

Hi,
MultiRowTabLiteforFx.uc.js suppresses the "Margins & Header/Footer" tab in the print page setup.
Go to FF's main menu -> Print -> Page Setup

Here is picture that shows the correct "Page setup" on the left hand side and on the right hand side the suppressed "Margins & Header/Footer" tab caused by MultiRowTabLiteforFx.uc.js equally of its version.

Does anyone have an idea what needs to be changed in the script for the print page setup to work properly?
