I have similar issues with both Firefox 25.0.1 and Thunderbird 24.1.1. I have multiple extensions installed on both, but neither has a single same extension (so either this may be caused by multiple different extensions or something else is going on).
Additional info: - I have been hit with this problem every now and then since around Firefox 10 and Thunderbird 3. I think this is a problem in Ubuntu XUL core because the problem is visible with both Firefox and Thunderbird. - I have been hit with this problem using at least Gnome 2.x, Unity and Cinnamon desktop environments so I'd guess this is not related to the window manager. I haven't used KDE long enough to verify if this problem is visible in that environment, too. - Since I have reduced the system latency(*) I've hit this problem more often; I guess it's some kind of race condition between some paraller threads or processes doing something. The system is running on i7-3770k with HT enabled (without overclocking).

The focus (and key and mouse events) are still sent to a different window even after it has been selected for the foreground by click or ALT+TAB,ALT+`. Initially I experienced this on a dual-head display, but even when the window is moved from the external monitor to the built-in laptop monitor, events are routed to the wrong firefox window. This issue has survived an apt-get upgrade and a reboot, and is still occurring.
