Yes, this undocumented feature stopped working since we implemented another way for the folder view selection, see bug 700976. The release notes
https://www.mozilla.org/en-US/thunderbird/52.0/releasenotes/
say: New: Folder pane toolbar and folder view selector (replacement for folder view arrows).
Also see: https://support.mozilla.org/en-US/kb/new-thunderbird-52

Please remove the CSS code from your userChrome.css. Please use the official way to switch folder views by enabling |View > Toolbars, enable Folder Pane Toolbar|. The folder view switcher should be displayed by default, if not, right-click and Customize and drag "Folder Views" there.

There have been complaints about the arrows no longer working in bug 1364791, and apparently whoever wants the arrows back can use an add-on.
