Apple competes with open source all the time. Linux is the most obvious example, but most consumer open source software competes with either Apple or MS, and open source is almost always losing. I think what makes this unique is that Firefox is an unusually well designed product that appeals to the average consumer in ways most open source software does not. It also had a head start, and has a huge user base. In fact, you could argue that unlike usual, Apple is actually winning on technology, and not usability, since perhaps the biggest advantage to firefox is its ability to install plugins.
