firefox now shows characters as squares instead of normal letters so that it is unusable. I removed all history but it did not change anything. I created a new profile but it is still the same. I found one thing that works: untick "allow websites to use their own fonts". But why? I have 2 F25 computers, this happens only on one of them (the one on which I use the nvidia proprietary drivers).
