Reproducible: Always Steps to Reproduce: 1. Select option to show tab bar when only one web site is open. 2. Leave only one web site open and go to some page. 3. Click on the X in the tab bar to close the tab. Actual Results: The tab is blank, but I can go to the previous page using the Back button. Expected Results: The tab should be blank and the Back button should be disabled, just as if a new tab was created with Ctl-T.

Actually, I like current behavior.

This has helped me sometimes when I accidentally closed the last tab. But I guess that is bug 254021

Hm, I didn't mark this NEW, does it do it automatically?

dupe of bug 281012?

Yep. *** This bug has been marked as a duplicate of 281012 ***
