Robert:

I just sent a post to the list containing an attached screen dump of the
"problem" very much enlarged, taken from firefox on Centos 7.

That post is being held for moderation, so it may not appear on
the list...

so, what I see is: the pairs "ff", "fi", and as one other posted
mentioned "fl" are all being rendered as a ligature. On my screen
it looks fine, but it sounds as you're seeing a ligature from some
other font. The sans serif font in which my firefox renders it,
ligatures look almost exactly like separate characters, unless you
blow them way up, as I did.

do you, perhaps, have your firefox configured to use fonts other
than those called for by the web page?
