Facebook messenger (messenger.com) is way more hostile; you can open it with "view desktop site", but whenever you tap the input box it focuses and unfocuses immediately, making it mostly unusable.

Is mbasic facebook still a thing (for messaging)? I'm in the fortunate position of not having to use fb messenger for most of my contacts.

Edit: despite what I said, I think the mobile reddit browser experience is horrible indeed. Usually I change the url to go to i.reddit.com instead, which is much more usable.
