Italic fonts in Firefox Interface [solved]

Hold on Cowboy

This blog post is pretty old. Be careful with the information you find in here. The Times They Are A-Changin'

A coworker had this problem. After installing a plugin-update, the fonts on her Firefox interface were all italic. We combed over the preferences to no avail, then a simple Google search revealed the answer.

Open Font Book
Find Lucida Grand Regular
Right Click > Reveal in Finder
Delete it. AAHHHHH!!!! Yes, I’m sure, delete it,
Witness the true power of a fully operational Mac Station, it suddenly recreates the font for you. Amazing

Now of course you need to restart Firefox, and everything was cool.
