Hi. I updated firefox on November 6th and now the font changed to a CAPS font on all web pages. I've tried to reinstall Firefox, but it doesn't help... I've tried to change the font settings, but they are at Times New and the fonts doesn't change no matter what i choose.

Thank you! This worked. Any idea what causes this? It didn't take effect until i used safe mode.

Hard to say. It could have been a corrupt file that was replaced.
