Bug 211226: www/firefox: crashes when typing character in search or URL bar
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211226



--- Description ---
After upgrade to Firefox 41, it started to crash when typing a character in
search or URL bar. This happens once in a few days. App doesn't close its
windows, but starts to "flash" and doesn't accept any input.

Last lines from the output are:

Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70:
non-double matrix element
Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70:
non-double matrix element
Fontconfig warning: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 78:
saw unknown, expected number

The fun part is that /etc/fonts doesn't exist (it's a /usr/local/etc/fonts in
FreeBSD). I've googled and seems similar error occurs with Steam and Telegram
on Linux. The conclusion in these topics was "outdated fontconfig used by app
X".
Wondering if something has changed in Firefox 41 fontconfig part.
