Mozilla DTD format

Mozilla makes use of a .dtd file to store many of its translatable elements, the moz2po converter can handle these.



  • Comments – these are handled correctly and integrated with the unit
  • Accelerators – if a unit has an associated access key entry then these are combined into a single unit
  • Translator directive – all LOCALIZATION NOTE items such as DONT_TRANSLATE are handled and such items are discarded
  • Entities – some entities such as & or " are expanded when reading DTD files and escaped when writing them, so that translator see and type & and " directly


  • We don’t expand some character entities like <, & – this doesn’t break anything but it would be nicer to see © rather than ©
