Did you mean Mozilla doesn't render Greek letters with diacritic marks
correctly? There are a few different factors that affect Greek/Latin/Cyrillic
letters with diacritic marks. 

- The way they're encoded : precomposed using a single Unicode code point or
decomposed. Greek capital letter alpha with tonos has its own code point so that
it's likely that it's represented with that precomposed character (U+0386)

- Fonts : installed on your system and specified by the author of a document :
whether they have glyphs for precomposed characters (e.g. U+0386),  whether they
have necessary GSUB/GPOS tables (if they're opentype fonts), whether  they have
glyphs for combining diacritic marks that get them rendered more or less
'correctly' when they're preceded by base characters (if GSUB/GPOS is missing or
the rendering engine doesn't support them.)

- The version of usp10.dll installed on your Windows : The newest version of
usp10.dll (uniscribe) can handle combining diacritic marks for
Greek/Latin/Cyrillic letters, but old ones can't.

- Probably, whether you enabled 'complex script support' in the control panel
(if you're on Win 2k/XP) does also matter.

- Oops. I was about to write one more, but just forgot ....

So, you need to provide more details including at least a couple of sample
documents or document URLs and screenshots comparing Mozilla and MS IE (if the
latter does it right or differently from mozilla if not correctly)

And, probably, this is a dupe

You should take this up with the owners of the site. It declares itself as being
in the ISO-8859-7 encoding, where capital Alpha with tonos is encoded as 0xb6,
but  parts of it are actually in Windows-1253, where it is encoded as 0xa2. You
can see this by changing the encoding between ISO-8859-7 and Windows-1253 from
the menu at View | Character encoding | More encodings | West European.

With ISO-8859-7 you will see "?ρθρα" in the main page, but "Άρθρα" in the side
bar. With Windows-1253 you will see "Άρθρα" in the main page, but "¶ρθρα" in the
side bar. The situation is much the same in IE and Opera.(To read this comment,
set the encoding to UTF-8 if it isn't set already)

This is not Mozilla's problem, resolving INVALID.
