Firefox has a far more diverse selection of extensions. And Firefox extensions are far more powerful than Chrome extensions with much deeper integration into the browser. This can also be a curse with a poorly written extension, though. It's worth noting that multi-process is why Chrome has a much higher memory footprint than Firefox these days for users running several tabs. Firefox pulls out plugins (Flash, etc) to a separate process so when they crash, they don't take out the browser. It will still cause the browser to pause for a few seconds as it waits to be sure Flash is hung up before asking you to stop the plugin.
