I'm having a lot of frustration trying to edit the shortcuts in the New Tab page in any kind of smooth and easy manner. While I recognize that having sync turned on means that Firefox destroyed my pinned shortcuts on this PC when I logged into Firefox on the new PC I am setting up, it's incredibly inconvenient, and the lack of options in regards to editing makes replacing all of it really, really awful. I have no ability to see the history of my shortcuts, nor can I save configured shortcuts and restore them should an improper sync destroy my previous settings. If I want an empty tile, I have to go through and repeatedly dismiss everything from my history to stop more of my visited websites from replacing said tile. Is there something obvious I'm missing here? If not, is there any kind of way that more customization options for New Tab shortcuts might be suggested?
