Using the helper app by default for compatible sites

Hi, I've recently switched to using FF on Android and one thing I've noticed is that if I were previously to browse to a site for which I had an app installed, Chrome would automatically switch out to the compatible app instead of viewing through the browser. I've noticed Firefox can do this, but I first have to wait for the page to finish loading and then tap the droid icon in the address bar (next to the reader view icon - check the attachment).

My question is can this be set to happen automatically? I've had a look through the settings and haven't found anything related to it. It's taken me a while to even figure out that the Firefox term for this is "helper app".
