For months I have been troubled by a double line space between paragraphs, in certain forums including (as some may have noticed) this one, when I posted anything.
I have just resolved it, thanks to the help of the member of another forum, its a Firefox setting which had somehow changed.....
Goto the FF Configuration Editor :- In the
address bar, type
about:config and press Enter.
Accept any warnings.
Navigate to and toggle preference for
editor.use_div_for_default_newlines
