If you drag the bird or the sun out of screen area, drag&drop turns into moving
that object no matter whether mouse is clicked or not. The only way to escape
from this is to click on other object.

Reproducible: Always
Steps to Reproduce:
1. Go to http://www.mozilla.org/start/1.0/demos/eagle-sun.html
2. Drag the sun to the bottom edge of page (scrollbar appears)
3. Scroll page down
4. Drag sun more down
5. Drag sun back
6. Move mouse
Actual Results:  
The sun continue to move on mouse move, though you have released mouse button

Expected Results:  
The sun should not move if not drag&dropped

It's because the script of that page is buggy. The mouseup event handler is on
the draggable object itself.
That means when you're dragging the object and you happen to release the mouse
button while the object is not under the mouse pointer, the mouseup event
handler function is never called.

Changing what.onmouseup = endDrag; to document.onmouseup = endDrag; would solve
the bug, I think.

Martijn Wargers, as I read your comments, I understand that this is not Firefox
error. Still, this is bug, and it probably has some category to fit in, but I
can't figure out which one I should switch it to. Can you help me?

I should have updated the title as Martijn changed category, but I forgot.

This bug has been buried in the graveyard and has not been updated in over 5 years. It is probably safe to assume that it will never be fixed, so resolving as WONTFIX.
