How can I enable Firefox for Android reader mode for my site?

Question

I'm creating a site which will be responsive, and suitable for mobile devices. Earlier I discovered Firefox's reader mode, which was available for certain sites, and provided a clean view for reading. However, when I visit my site, I don't get the option to view in reader mode.

I'm curious how is it possible to enable it to my site, since it's a great feature.

Answer 1

Reader mode in Firefox for Android is based on the readability.js code and the publisher guidelines for Readability should probably help:

Answer 2

Typically this results from bad markup. Check your site with W3C validator to see if this is the case.
