I will admit that I just took pawadu's word for it. I personally had no idea if it is possible to disable pdfjs or not.
That being said, I will also agree that it is convenient sometimes but it is much slower and much less compatible than native viewers, making it useless for me about half the time. Still, I see no reason why it needs to be integrated into firefox instead of being just an addon (even if it is installed by default).
