firefox on fedora 25 unable to apply css rules?

[François Patte]

Bonjour,

I just installed fedora 25 on my laptop. firefox 50 (or 49) is unable to
display fonts if I put this css instruction:

* {
  font-family: Freeserif, Helvetica, sans-serif;
}

If I comment this in the css file, I can see the text if not: all
decorations, and images are displayed but no text appears!

I tried with google-chrome and the page is correctly rendered.

Thank ou for any clue!

Are you using the same file for both, or just typing the same
information into each browser's CSS files?  If they're separate files,
check carefully for any typing errors.

For what it's worth, specifying a serif, then two sans-serif fall-backs,
is a bit odd.  Not that /that/ should have anything to do with your
issue.

I read this:

http://www.math-info.univ-paris5.fr/~patte/projet-ycart/

No problem with firefox 42 on fedora 21, no problem with firefox 50.1.0
on fedora 24.

Problem occurs with firefox 49 or 50 on fedora 25 but no problem on this
platform with google-chrome.

On fedora 25 I have the same problem if I read localy the same files
through httpd server running on localhost public_html

For me, this site is rendered identically by Firefox (50.1.0) and Chrome 
(55.0.2883.87 (64-bit)) in Fedora 25 (KDE).

In Firefox, the fonts font instruction ( font-family: Freeserif, 
Helvetica, sans-serif;}) is obviosly applied, you can switch it on and 
off with Firefox' web developer tools.

I can see, using these tools, that the used font-family are correct, but
no text is displayed in firefox! Only decoration and images.

I use xfce4.

I tried with another user account on the same machine and the problem s
the same.

fc-list shows that  FreeSerif fonts are present.

Have you tried viewing that font in some other program?  Would help to
know if it's the font or Firefox.

Try re-ordering the fonts so it's "font-family: Helvetica, Freeserif,
sans-serif;" (assuming you have a Helvetica).  Also try FreeSans.

Libreoffice, xelatex uses freefonts without any problems....

I haven't Helvetica, but replacing FreeSerif by Arial works (text is
displayed) .

If I suppress FreeSerif and keep Helvetica (which I haven't) firefox
uses as replacement font TeXGyrHeros....

So it seems that firefox sees that the FreeSerif family is installed but
is unable to read them! (permission are correct ie. 755 and 644)

What is strange is that the same firefox version(50.1.0)  on fedora 24
reads these pages without problems. Would it mean that somme dependency
package for font rendering in firefox is faulty?

I falled back to fedora 24!

This solved this issue, and some others:

strange behaviour of nouveau driver (see my other post about it)

shutdown did not randomly work (sometimes yes, sometimes I had to stop
the computer using the power button)

And all issues I had not the time to see....
