So I've been organizing my bookmarks recently, I deleted a bunch which worked as expected. But there is a specific folder that no matter how many times I try to get it deleted, it will comeback. This happens on my PC and my laptop. I've turned off syncing on both devices as well as logged out from any other Firefox based browser like Zen. Also, this folder used to be well organized, now everything inside is messed up, and children folders dupped.
