--- Comment #1 from Alexander Ploumistos  ---
Hmm, it seems that texgyreheros-regular.otf was installed only on the F25
machine and it had been pulled in by lilypond. When I removed texlive-tex-gyre
which also caused dblatex, texlive-collection-fontsrecommended,
texlive-collection-htmlxml, texlive-manfnt-font, texlive-mflogo-font and
texlive-wasy2-ps to be removed, firefox reverted to Nimbus Sans L. That could
be a problem when I'll have to use TeX stuff again.
