User:SOTO/Forum Archive/A new Tardis, at last/@comment-71.235.140.59-20150119202824 When I start scrolling down a page those left side icons Table of Contents, Edit, Tools icons disappear and the only way to get them back is to refresh the page. Is this intentional? I'm on Firefox with a OS X Yosemite.
