Created attachment 8705900 [details] [diff] [review] 0001-Bug-XXXXXXX-Synced-Tabs-entry-on-history-panel-is-al.patch There is a "Synced Tabs" item on the history panel. This has |disabled="true"| defined in the XUL and while the code correctly manages the hidden state of the item it never removes the disabled attribute. The end result is that the item is correctly hidden when Sync is not configured, but shown and disabled when it is.
