For the benefit of anyone who found themselves here trying to find a way to reorder the tiles on the "new" New Tab page, there's a solution here[0], in the Mozilla support forum. Basically, toggle about:config?filter=browser.newtabpage.activity-stream.enabled to "false", rearrange the tiles, then toggle back to "true". You might need to force-reload (Shift+Ctrl/⌘+R) the New Tab page to see the results. [0] https://support.mozilla.org/en-US/questions/1178312#answer-1030416

Aaron, given that we're close to 59 freeze, is the current PR's behavior acceptable to ship as is? In particular: - the dragged item jumps back to its original spot when the drag position is not directly on top of a site (i.e., in the whitespace between sites) - on drop, there's a flash of the original sites ordering before it updates - the original site's position gets its meatball menu shown for the new site (even though the pointer is where the site was dropped)

Looks good!
