I love the pinned tabs feature. However, when I pin tabs, any more than 5 won't show up on the contracted sidebar. In the example I've uploaded, t here are 8 pinned tabs, viewable in the expanded sidebar as icons four in a row across the top. The second image shows the same window contracted, with only five of the 8 pinned tabs visible. The others are still there, but I can't see/access them without re-opening the sidebar. How do I get Firefox to show all the pinned tabs in the contracted view?

Thanks!
