Hello, I've had the problem for a while now, and finally decided to do something about it. When I am visiting certain websites the fonts for the headlines are all messed up. I attached two images of the official website of berlin, one opened with firefox, one opened with safari. You can see that the font problem is primarily applying to headlines. Since this doesn't happen on every website, I was thinking this could be due to firefox not being able to handle one certain font. You will also notice, that firefox doesn't display german letters such as ä, ö and ü. I have already tried playing around with the performance settings, and my language is set to german. I am thankful for every new idea. Cheers Tom
