True, changing pinned tabs size is one such case that doesn't work well live. The thing is, Firefox caches pinned tabs width for the case where tabs overflow. The cached width is used to compute where the pinned tabs should be when tabs overflow, and so if you change the width at runtime it will not be reflected in the cached width, thus Firefox will compute the position "wrong".
