[solved] I can't see all buttons in Firefox

A lot of the buttons are just shown as rectangles in Firefox 38 (Iceweasel, Debian 7).
Like this:

Unfortunatly not all of them show some text when i hover the mouse over them, so it’s more of a blind flight then.

I restarted the browser with Adblock and Ghostery disabled, but there’s no difference.

Some help would be great.

That looks like unicode rendering problems to me.


You’ve showed me the right direction, thank you!
I had just had to allow websites to use their own fonts, et voilá :smiley:

Ogs looks really nice now. :thumbsup:
