This extension auto-hides your Firefox/Thunderbird's tab bar. It can also relocate the tab bar to the bottom of the browser window.
It supports Thunderbird since version 2.0.
In version 2.6, a hot key is added to switch the tab bar on/off quickly. By default, it is disabled. To enable it, open the Options dialog and check option "Double-press Ctrl key to show/hide Tabbar". After that, you can press the Ctrl key twice to hide/show the tab bar.
In version 2.6.1, another hot key Alt is added. Those who do not want to use Ctrl as the hot key can use Alt instead. Enable it in the Options dialog.
After you install the extension and restart Firefox/Thunderbird, the tab bar is hidden automatically. After the tab bar is hidden, a tiny plain bar would be placed at the tab bar's old position, e.g. the edge of the content panel. By moving the mouse to the plain bar, you can make the tab bar shown again.
Right click on the tab bar, you can see a menu item of Autohide Tabbar. Use it to toggle the feature on or off. It will only make the change on the current browser window and any new browser window you will open. To turn the feature on or off for all currently opened windows, use the next method.
You can also toggle this feature by the extension's Options dialog, which is accessed from the menu Tools|Add-ons|Extensions. Select our extension Autohide Tabbar and click the button Options/Preferences. In the Options dialog, toggle the checkbox of Enable Autohide Tabbar.
When you are toggling the tab bar on and off with the mouse, the web page in the content panel would looks jumping up and down because the content panel is being resized against the top edge. Some people may find that annoying. An option was added in version 1.1 to allow you relocate the tab bar to the bottom of the content panel so that the web page would not look jumping. To do that, open the Options dialog via the menu Tools|Add-ons|Extensions|Autohide Tabbar|Options(or Preferences), and toggle the checkbox of Put Tabbar At Bottom. The new setting will take effect after the next time you restart Firefox/Thunderbird.

As always, after the installation, you need to restart Firefox/Thunderbird.
The Options dialog can be opened from the menu Tools|Add-ons|Extensions|Autohide Tabbar|Options(or Preferences). Here are the options you can change:
- Enable Autohide Tabbar: if it is checked, the extension is enabled. By default, it is checked.
- Put Tabbar At Bottom: if it is checked, the tab bar is placed at the bottom of the browser window -- above the status bar. After you change this setting, you need to restart Firefox/Thunderbird. By default, it is not checked.

- Delay showing tabbar: how long in milliseconds to delay showing the tabbar when the mouse moves into the tabbar area.
- Double-press Ctrl key to show/hide tabbar: use the Ctrl key as the hot key to show/hide tabbar.
- Double-press Alt key to show/hide tabbar: use the Alt key as the hot key to show/hide tabbar.
Notes & Tips
This extension respects Firefox's own Tabs Auto-hide option -- which auto-hide the tab bar when there is only one tab. So if you have only one open tab, no matter where you point your mouse, the tab bar will not be shown. To disable Firefox's own Tabs Auto-hide, open Firefox's Options dialog via menu Tools|Options (or Edit|Preferences in Linux), and click icon Tabs, then check Always show the tab bar. It is recommended that you should do that.
If you place the tab bar at the bottom, you may find it takes more effort when you use the '+' button on the tab bar to open a new tab and then type in the address bar. You may consider add a New Tab button to the menu bar so that you do not have to move the mouse all the way across the browser. To do that, right click on the menu bar and select Customize..., and drag the New Tab icon to the menu bar. You can, of course, always use the shortcut Ctrl-T to open a new tab.
This extension works with mouse. If you use only the keyboard, do not install it.
Sometimes when the mouse quickly cross the hidden tar bar, the tar bar will be shown but not be hidden again. That is because our extension can only receive the mouseover event of the tiny plain bar but the mouseout event of the just-shown tar bar may be lost. If that happens, just move your mouse a little bit on the web page to trigger the hiding of the tar bar.
When you open a new tab, the tabbar is not shown. That gives you better privacy. If the new tab is not shown (e.g. when you open it by middle-click a link), you can switch to the new tab by using shotcut Ctrl-PgDn. You can also use other shortcuts to quickly switch tabs, e.g. Ctrl-1 to the first tab.
Install another extension Packed Menu together and you would get a neater interface.
