If the page's current title is so long that all of it doesn't fit in the tab's caption, if one switches to a page whose name is smaller, the last part of the previous page's text will still be visible in the place of the close tab button.
This only seems to happen when a single tab is open, and the close button isn't present, but browser.tabs.closeWindowWithLastTab is false.
This happened in Firefox 3.6.

Reproducible: Sometimes

Steps to Reproduce:
1. With a single tab open, enter a page with a long name
2. Change to a page whose name is really short
Actual Results:  
If all went well, part of the previous page's text should appear on the right of the tab.

Expected Results:  
Show blank space.

It must be on the first and only tab open. browser.tabs.closeWindowWithLastTab must be false. The tab bar should always be visible.
