This works for me. CAn you provide screenshots before and after rotating?

The screenshots were taken with a Nexus 4, I can reproduce the same behavior with Nexus 7.

Forgot to add that if I double tap on the screen to initiate a zoom, the text is re-flowed.

Strange. I'm also testing on a Nexus 4 with the exact same build you said in comment 0 (i.e. the latest 27 beta build) and I don't see this. It reflows fine for me.

Aaron, can you repro?

Works for me. No alterations to preferences, no add-ons.

I looked into about:config and see that I had browser.zoom.reflowOnZoon set to true. I reset the preference and it works now. I don't remember going to about:config to change this (and it seems unlikely that I did it on both devices). Looks like this was exposed in the UI according to https://bugzilla.mozilla.org/show_bug.cgi?id=900564 .

It may not affect new users, but maybe something should be done to reset this preference so existing users don't get this broken behavior?

It's probably too late to do this for FF27 since that'll go out the door early next week.
