oh yeah. i get that with twitter. view a video, close it and you ve lost your page . i dont know why this even happens but it s more annoying than i could ever imagine. My solution is to switch to chronological-view-only, so at least i can tell whether i ve seen my whole feed
What I hate even worse though is endless scroll... give me damn pagination with buttons! So I can reload the page and not worry about losing my spot, or accidentally scrolling away... let me use the back button on my browser!
