I think there's a good reason why no mobile browsers implement desktop style tabs. Even the Vivaldi screenshots in this post show just 2.5 tabs with significant truncation of all the visible tabs. On tablet this might work (where other browsers have a more traditional tab view), but on portrait phone this seems like a terrible idea.
