Why does it keep telling me to restart in 32 bit mode?

A yellow button appears with a notification along to top of the window below the different link tabs. It tells me it would be better in 32 bit mode. I click the button and firefox restarts.

Basically, you go into "Get Info" for the Firefox icon and check off "open in 32 bit mode"
