Jeff, think you're running into a Layer 8 OSI problem with your Firefox there buddy..
I admit Firefox is not the best browser but I like the pretty themes I have and the fact I have 4 rubber duckies smiling at me every day. Who wouldn't want that sort of connection with someone? Although for outright security Chrome seems best but if you are running patched Adobe, Flash and Java you're unlikely to get any sort of drive by downloads of exploits unless you are a numpty!
The new FF10.x isn't to bad really. Suits Windows 7 theme well. Chrome as standard looks very crayony and trust me I am the Crayon King.
