How to restore the menu header in Thunderbird 17
Thunderbird 17 is currently offered as a beta version. If you have installed the upcoming version of the email client on your system, you may have noticed the new look of the header area of the program. Mozilla decided to remove the title bar from the email client to use the extra vertical space for contents displayed in Thunderbird.
You furthermore may have noticed a new settings button in the main toolbar that leads to a one-button menu that Firefox has been using for a while now by default. The menu bar on the other hand is still displayed in Thunderbird if you have used it before.
The changes allow you to remove the menu bar - if active before - to save menu bar and title bar space in Thunderbird for other contents. The first toolbar displayed is the tab bar followed by the main toolbar of the browser.
I have to admit that I do not mind the title bar change, as it did not display any information that I needed anyway. I did mind Mozilla removing the website titles from Firefox's title bar, but since Thunderbird is not displaying mail information here - only the mailbox you are currently working with - it is not a big deal for me.
Removing the menu bar on the other hand takes some getting used to time. I have not used it that much though, mostly to open the settings or add-on listing, and those two are accessible directly in the new toolbar menu.
If you do not like the changes, for whatever reason, you will be glad to know that you can easily restore Thunderbird's header to the way it was before.
If the menu bar is not displayed anymore, right-click on the new Thunderbird button (shown on the screenshot above) and activate the menu bar again.
You need to open the advanced configuration if you want to display the title bar in the email client again. For that, click on Tools > Options or Menu > Options, and navigate to Advanced > General > Config Editor here.
Filter for the preference mail.tabs.drawInTitlebar and double-click it to set it to false. You should immediately see the title bar in the Thunderbird email client again.Advertisement
