Replying to my own mssg! . . Just thought of a bodge . . select a free draw pen big enough and using background colour to overwrite the mistake? . . but surely Mozilla can supply a better eraser??
New PDF editing on Firefox
New PDF editing functions on Firefox are OK , but make a mistake and it appears there's no delete or Eraser options!!
Anyone know a way to delete or wipe out a mistake using the free draw pen, for instance?
