Actually, the mobile browser had a major overhaul a few years ago. I had switched to mobile Firefox just a few months before the new version and performance has vastly improved. Usability is okay (sometimes I wonder if these folks use their own software). But otherwise not much has changed since then.
They remotely installed a Mr Robot addon (US only), because they thought their user base also liked the show. It was a puzzle/game or something, an unpaid promotion.
