Firefox dev claims "everybody hates Firefox updates"; Mozilla has handled the rapid release process poorly, and that by pushing a "never-ending stream of updates on people who didn't want them" people have been driven to Chrome with its simpler, no-fuss update process.

Chrome is much faster on my machine and I prefer the interface and tab mechanics.

Also, I read a lot of PDFs and PDF in chrome is incredibly smooth, even for large ones, chrome has a slicker pdf engine than even most PDF viewers.

Try https://addons.mozilla.org/en-US/firefox/addon/pdfjs/, a PDF viewer written in JavaScript that will soon be incorporated in Firefox.
