Thank you for your review. Yes, I kept the "management" features really minimal and just enough to move/delete/rename one item at a time, because any more than that and I felt that I would be reinventing a wheel (Firefox's native Library window) that was made by people way more competent than me. I took many shortcuts to make the code as light as possible, that is why the entire page reloads every time there is a change, or why only one single item can be moved at a time.

My hope when I started this little project was that Firefox would eventually have a better New Tab page, that could do all this large-scale management correctly...

So I can't promise that I'll be able to implement all those features, but I'll try to make it possible to select multiple items, and will try to implement contextual actions to edit/rename/remove/open any number of items.

Now about your 2nd issue, I'm puzzled because it **really** shouldn't be doing that. May I ask what rules you have, on what version of Firefox?
