1273199 - Allow both mail.tabs.drawInTitlebar and mail.tabs.autoHide to be True when window is maximized

Status: UNCONFIRMED

(Thunderbird :: Toolbars and Tabs, defect)

Description

[Charles]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0
Build ID: 20160502172042

Steps to reproduce:

On my netbook I always run Thunderbird in maximized mode.

I enabled both mail.tabs.drawInTitlebar and mail.tabs.autoHide to provide minimalist UI on my netbook


Actual results:

The Menu bar refuses to draw in the Titlebar, apparently because I also have enabled mail.tabs.autoHide, apparently because a decision was made to disable mail.tabs.drawInTitlebar when mail.tabs.autoHide is enabled, due to the fact that one cannot move/drag the window around by the menu bar when it is drawn in the titlebar.


Expected results:

Thunderbird should recognize that it is running in maximized mode, and allow both prefs to be true while in this state the window is maximized.

So, if a user sets both prefs to True, they are both True when the window is maximized, but mail.tabs.drawInTitlebar flips to false if the window is un-maximized.

Question though - maybe there is another bug that should be filed.

Why/how can Firefox allow the window to be moved by the Menu Bar when it is drawn in the Titlebar? Maybe a more correct fix would be to fix TB so it works the same way?

So, upon revisiting this today, I opened bug 1336959 to allow moving the window by grabbing a blank space on the Menu Toolbar.
