Hello,

This can easily be resolved if you desire the keep tabs hidden. You can install "Hide tab bar with one tab", an extension hosted on Mozilla's add-ons site, which will restore the ability to hide the tab bar.

Thank you and I hope this helps!

Have you tried this add-on? https://addons.mozilla.org/en-US/firefox/addon/fullscreen-toolbar-hover/

The add on is not the solution. Why cannot you allow the address bar to be hidden as it was in v. 28 ?? Do we now have to start using Safari again?

Agreed. The address bar is not the tab bar. I would like to resize or hide it. It takes up the entire length of the screen... ridiculous!

See:

• Hide Navigation Bar: https://addons.mozilla.org/firefox/addon/hide-navigation-bar/

You can look at the Classic Theme Restorer extension to restore some functionality that was lost with the arrival of the Australis style in Firefox 29.

• You can check out the settings of the CTR extension via its Options/Preferences button on the "Firefox/Tools > Add-ons > Extensions" page.
• You can find extra toolbar buttons and more toolbar settings in Customize (3-bar Firefox menu button > Customize)
