(Firefox :: Tabbed Browser, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b1) Gecko/2007110904 Firefox/3.0b1

Seen a few times with 3.0b1: clicking the middle mouse button opens a new tab and immediately focuses that tab (even though the setting is disabled in the options-menu). So far, it is hard to reproduce. First saw this problem while navigating http://www.ubuntuhomeserver.org/

Reproducible: Sometimes

Steps to Reproduce:
1. Open a site
2. Middle click on a link
3. Wait for the magic to happen
Actual Results:  
A new tab is opened with the contents of the referred page. Incidentally, this newly opened tab is directly focused (i.e. the active tab changes).

Expected Results:  
A new tab opens at the end of the list, but does not receive focus if this option has not been specifically set by the user

Could not reproduce. Middle clicking every link on the mentioned page opened a new tab without focussing.
