To reproduce this problem, it is necessary that Firefox remember some autocomplete entries for a text box.  As an example, I shall use the "usernmae" field of the Gmail login page, but the problem is reproducible with other text boxes, too.

Reproducible: Always

Steps to Reproduce:
1. Make sure that Firefox remembers at least one entry for the "username" field of the Gmail login page.

2. Go to the Gmail login page and make sure that the username field does not contain any text.

3. Doubleclick the username field, but after the second click, keep holding the mouse button.

4. The autocomplete dropdown will appear.  Move the mouse pointer over an entry, and release the mouse button to select it.

5. The field will be filled with the selected entry, but since the mouse pointer was moved down, it is not over the textbox any more.  In spite of this, it is still connected to the textbox in a certain way and moving the mouse causes the text to be selected in the textbox.

6. Click once.
Actual Results:  
After the last click, the dropdown appears again.

Expected Results:  
The dropdown should not appear.  The connection between the textbox and the mouse cursor should have been broken when the button was released after the doubleclick.

So why would it be nice to fix this seemingly unimportant bug?  Because it would provide a quicker and more efficient (less clicks) way to fill text boxes with autocomplete entries.  This is similar to how Windows menus can be used in two ways: click, move pointer over menu entry, click again;  or, simply click and hold, move pointer over entry, and release button.  

Analogously to how menus can be used, it would be nice to be able to doubleclick in text box to bring up autocomplete menu, move pointer over entry, and release button to select entry.  This *almost* works at the moment, but this bug cripples the experience.

this seems to be an old bug since i experienced this in former FX releases too.
though i cannot find any dupes ...

in steps 4/5 after releasing the mouse button, just move the mouse pointer over the textbox and then right/left to see the bug.
