Status: NEW

(Firefox :: Toolbars and Customization, defect)

Description

[arni2033]

>>>   My Info:   Win7_64, Nightly 49, 32bit, ID 20160526082509
STR_1:
1. Create new bookmark folder "asdf" in bookmarks bar
2. Move bookmarks toolbar items to menu bar. Right-click Australis menu button, disable "menu bar"
3. Press F10 to show menu bar
4. Click on "asdf" folder
5. Click on content area several times
 (bonus - there's already bug. You should only continue if you disagree)
6. Press F10

AR:
 Step 5 - "asdf" folder's submenu disappears. Menu bar is still visible.
 Step 6 - Menu bar is still visible

ER:  Either X or Y
 X) Step 5 - Menu bar should close, because I closed all submenus and clicked on content.
             Reference: it always closes in this case, if bookmarks folders are not involved.
 Y) Step 6 - Menu bar should close. Even if somebody disagrees with (X), F10 button is used
             to _toggle_ menu bar. Therefore it should close the opened menu bar.

Notes:
1) Step 2 is required to make bookmarks toolbar items easily accessible. GoogleChrome has a special
   shortcut to show bookmarks toolbar items, however there's no such shortcut in Firefox. The only way
   to make bookmarks toolbar items easily accessible is to place them in menu bar, that has a shortcut
2) In steps 3 and 6 only shortcut F10 is suitable, because Alt is causing terrible bug 770773
