Justify text (chrome/FF/etc.)

Dear

I'm looking for solution to justify text; all solutions found in this forum doesn't work with Firefox, why ?

I'm testing something like that:

Quote

body p, .sqs-layout .sqs-block.html-block p, .sqs-layout .sqs-block.markdown-block p {
  display: block; /* inline-block; */
  text-align: justify!important;
  text-justify: inter-word !important; }
}

but without success with ff.

Could you help me ?

Best regards for all !
