I am running on an old SLED-11 linux box and while Firefox ESR 38.6.0 runs OK, new versions crash with "symbol lookup error: /opt/mozilla/firefox/libxul.so: undefined symbol: FcConfigReference"

Note that the current version is 38.8.0 ESR that has still be maintained:

Doesn't that version work as well?


This issue looks font related (fontconfig):

Try this in user.js to see if that allows a newer version:

user_pref("gfx.font_rendering.fontconfig.fontlist.enabled", false);

The user.js change didn't fix the problem with Firefox 45: crashes the same. But ESR 38.8.0 runs OK so I will use that. Thanks.

SLE 11 on a new install had GTK 2.18.9

Firefox as of 46.0 and newer requires GTK 3.4 or newer to run. Also needs a GTK 3 theme to theme Firefox.
