Hello. Sorry for the later reply. Your first package, hyphen-ru_20030310-1ubuntu2~ppa_all.deb, contains the dictionary not in UTF-8 encoding. The second one, hyphen-ru_20030310-1ubuntu2~ppa2_all.deb, works as supposed.
As for LibreOffice, it hyphenates Russian text correctly with both your dictionary and the one installed from Ubuntu repository (KOI8-R-encoded). So, the bug is probably in Firefox, not in the dictionary.
