I am using the Firefox Nightly build on Android on Samsung Galaxy S5. Firefox Nightly is roughly the same as the usual Firefox, just a future unstable testing release. When I use it, I see all the sections expanded by default and I see the TOC as well. When I open the same pages in Firefox Android stable and in Chrome on the same phone, the sections are collapsed by default and the TOC is not shown. Behavior in Firefox Nightly, as well as in the Beta and Aurora versions, should be the same as in Firefox Stable. There can be difference in how different browser versions render HTML, but this doesn't look like such a difference.
Prioritization and scheduling of this bug is tracked on Trello card https://trello.com/c/pgF8zkXn
This appears to be an issue with Firefox OS https://bugzilla.mozilla.org/show_bug.cgi?id=1071620 I reached out to them.
* This appears to be a bug with Firefox nightly :)
