Does Firefox have a "strike-out" feature similar to the "underline", "bold", and "italicize" features?
A strike-out means a highlighted letter or word will be crossed out--the letter or word will still be visible but crossed out.

Do you mean this: <strike>this text has a strike-through</strike>
Where do you want to see or enter such text?
You can do that with <strike>text</strike> or <del>text</del> via HTML markup.
