Package: firefox
Version: 110.0.1-1
Severity: important
Forwarded: https://bugzilla.mozilla.org/show_bug.cgi?id=1820542
The bug description I've entered in the upstream bug:
------------------------------------------------------------------------
Steps to reproduce:
1. Start Firefox, configured with the menu bar enabled.
2. Click on "File".
3. Move the mouse pointer to the right (over "Edit").
Actual results:
The "Edit" menu sometimes appears, sometimes it doesn't. When it appears,
its first item ("Undo") is sometimes automatically selected, sometimes it
isn't. Similar issue with the other menus (History, Bookmarks...). The
behavior appears to be random.
Another test: If I click on "Bookmarks", its menu appears. Then if I move
the mouse pointer to "Tools", its menu sometimes appears, but not always.
When it appears, if I move the mouse pointer backward to "Bookmarks", the
"Tools" menu is still shown and its first item ("Downloads") gets selected,
even though the mouse pointer is over "Bookmarks".
The handling of the context menu over this textarea is also broken when
I make the "Languages" submenu appear: the position of the cursor over
its items ("English" and all the "French" variants) changes when I move
the mouse while the mouse pointer is actually over the first items of
the context menu ("Undo", "Redo", "Cut", "Copy"...).
Note that if I try to navigate in the menu items with the keyboard arrow
keys, this seems to be OK (whether I try with the menu bar or with the
context menu). So the problem seems to be with the mouse tracking.
------------------------------------------------------------------------
Note: by "selected", I mean that there is the cursor over it, as if
the mouse pointer were over the item.
Note also that unless one is fast and accurate enough in the mouse
movements, this means that one cannot have access to some menu items
with the mouse, e.g. the submenu "Zoom" in "View". So people with
disabilities might particularly be affected by this bug.
