This is different behaviour to Netscape 7.x for example, where the tab bar could be displayed or hidden independent of the number of tabbed windows open. It is also confusing because when the tab bar is hidden, so is the handy button to open a new tab. I could use CTRL+T or right-click on a link and select 'Open in new tab', but why not just have the tab bar stay in place? Because this behaviour is different from Netscape 7.x (which I upgraded from) I am assuming this is a bug and not a strange 'feature'. Closely related is the fact that the Tab Bar item under the View > Show|Hide menu is permanently greyed out, although the checkmark indicator seems to work (it is checked when the tab bar is opened by other means, for example). However if the tab bar is open, you cannot close it using this menu selection. Nor can you open it using the menu selection if it is closed. Reproducible: Always Steps to Reproduce: 1. Open a Mozilla browser - you get one page with no tab bar 2. 'View' menu > 'Show|Hide' > 'Tab Bar' will be grayed out 3. You cannot make the tab bar visible by selecting the 'Tab Bar' item 4. Open another tab, for example with CTRL+T 5. Try to make the tab bar disappear with 'View' > 'Show|Hide' > 'Tab Bar' - you will not be able to Conclusion - tabbed browsing controls are broken in the menu. Actual Results: You are unable to properly control tabbed browsing from the 'View' > 'Show|Hide' menu. Expected Results: It should allow the tab bar to be summoned or dismissed according to the setting of the 'Tab Bar' menu item. This item should not be permanently grayed out. It should respond to user input. I am using the 'Modern' theme.
Edit->Preferences->Navigation->Tabbed Browsing Tab Display [ ] hide the tab bar when only one tab is open If this box is unchecked, you´ll see the tab bar also if there is only one tab open. If you try to delete this tab with the x at the end of the tab bar, the tab bar is killed. If you then load a 2nd tab, it is displayed again, and stays open, when you have only one tab in the tab bar, until you try to kill this again. [x] select new tabs opened from links new wording, formerly known as 'load links in the background' When you middle-click on a link, a new tab is generated, and the link is loaded. this box checked means: the old tab is left, the new tab is shown this box unchecked means: you can go on reading the current page, and switch to the new tab whenever you want. My favourite setting, because I want to finish reading an article, while I´m loading some links from it.
