Not bad, but has issues
As soon as I updated to FF14, I regretted it, and I was hoping someone would submit a style to fix the toolbar. Unfortunately, this style is going to need some work before it looks like Firefox used to. I've attached images to show you what my toolbar looks like (default skin; no other app styles are active). The back button doesn't round off properly, and there are issues with button borders. I hope you can fix these issues. Good luck!
