Sub menus touching the bottom of screen do not expand upwards to show contents

[John McCown]

This is what someone told me.
I know the source of the problem. When an extension creates a Firefox popup menu, it has different position attribute values that determine the sub-menu placement.

https://developer.mozilla.org/en/XUL...popup.position

Essentially, the sub-menu is being created underneath the parent menuitem. Since the parent menuitem is at the bottom of the parent menu and next to the bottom of the screen, there is no room for the new sub-menu to expand. It should be creating the menu from bottom to top instead.

You shoud report this issue as a "Global Menu Bar Integration" extension bug. They need to change the extension code, so the sub-menu grows upwards when created next to the bottom.

Meanwhile, scroll the parent menuitem to the middle of the screen, before acessing the sub-menu.

This is my bug I have to take out the Unity appmenn to get my bookmarks folders to expand from the menu bar bookmarks. When I have a folder that is on the bottom of the page it will only show about 6 bookmark without have to use the up and down arrows. Anyone else having to do this?

I don't know who told you that, but they're wrong. In Unity, Firefox (and globalmenu-extension) have no control of the positioning or view of the menus. This is entirely controlled by the shell, and this is explained in the bug reporting guidelines (https://wiki.ubuntu.com/MozillaTeam/Bugs) which we ask everyone to read before submitting a Firefox bug.

This needs reassigning to the correct component, but I'm 99.999% certain that this has already been reported anyway

I'va attached as screen shot demonstrating this bug.
The global menu's sub-menu items to hot appear when menu list items are at the bottom of the screen.
In this example, the Fire Fox bookmarks sub-menu can not be expanded.
To recreate this bug, simply add enough Bookmark folders to Firefox until expanding them reaches the bottom of the screen.
(I experience this bug using Ubuntu 12.04 x64).

Additionally, I believe But 1022420 is a duplicate of this, ad will be tagging that one as duplicate.

Status changed to 'Confirmed' because the bug affects multiple users.

To add to Omer's summary...

Sub menus touching the bottom of screen do not expand upwards to show contents (between scroll arrows)

As part of the big bug review for 16.04 LTS, I have tested this on 15.10 and the bug is still there.
