It's way more than just pinning ! I organize my YouTube subscription in folders with themes like tutorials recipes and subfolders...you can do that on Firefox with the bookmark toolbar but in a less user friendly way and less visually pleasing way toi. what makes it worse is that it used to be possible on Firefox! It's not a deal breaker or anything ! But I miss that XD ! I had a hundreds of bookmarks organized on Vivaldi ! I still don't know how to "transition" that to firefox :/
