I tried asking reddit and chrome forum but I think it's a Mac thing, something with scrolling, anyway I can't drag bookmarks up or down a folder on the bookmark bar, it gets stuck, from googling I found at least one person with a similar problem and lots of others with bookmark dragging problems.
Sometimes I want to rearrange on the fly, or add a seperator, bookmark manager is better, but less convenient for things like adding horizontal seperators, here's what it looks like
Don't really have any ideas, I won't reinstall my whole chrome profile for it, too many bookmarks and things in my profile, I don't want to risk corruption, but any other ideas I'll try before I give up on it.
