I intent to unship tree pseudo-element selectors from web content in bug 1379031 [1].
This includes the following pseudo-elements: ::-moz-tree-column ::-moz-tree-row ::-moz-tree-separator ::-moz-tree-cell ::-moz-tree-indentation ::-moz-tree-line ::-moz-tree-twisty ::-moz-tree-image ::-moz-tree-cell-text ::-moz-tree-checkbox ::-moz-tree-progressmeter ::-moz-tree-drop-feedback They are used for matching anonymous boxes generated for some XUL elements. Since XUL is not accessible from web content, it makes little sense to support these selectors there. These selectors will still be available to chrome documents. Although they don't currently match anything on web content, there is still some risk for unshipping them. Specifically, some websites seem to use them for browser-sniffing.
