The only thing missing for me in Firefox on Android is text reflow. I just can't use a mobile browser without this feature.
There are some addons which try to emulate text reflow on tap, but it's pain to use at best.

Reader mode is a workaround, text reflow is the solution. It a reason to use Opera on Android. I wonder if it's so hard to implement that nobody else coded it.
Unfortunately the about:config setting for text reflow in one of the last comnents is not in Firefox anymore.
Ironically that page is an example of a page where reader mode doesn't work.
