I don't particularly like it on mobile (Firefox 63.0a1, aka Firefox Nightly on Android) because navigation between sections isn't intuitive, and it's not cleanly divided. Like it would be fine if each major section had one article a piece and you could tap on something to go into the section the article is in but I don't see a way to do it without tapping the menu button. It's two taps to navigate between sections where I'd prefer it to be just one from the front page.
The desktop version has a menu bar though, so no complaints there. I'll likely just use the desktop version on Mobile.
Aside from that, it looks good.
