Title:
  Keystrokes are hijacked by inactive window

Status in The Mozilla Firefox Browser:
  Invalid
Status in firefox package in Ubuntu:
  Confirmed

Bug description:
  Starting in a release from February, I've found that the front-most,
  active window often will occasionally not receive keystrokes. Instead
  they are being sent to the background, inactive window. The front-most
  window is shown as selected in the pager, while a non-selected window
  receives the keystrokes.

  I can alt-tab or click between windows, but cannot seem to type into
  one (or more) windows. Otherwise, clicking does all you expect it to.
  You can select menus of the window; you can even select text (although
  it's the "background window" grey instead of the "foreground window"
  blue).

  I tried to make sure that it was not an issue with X/KDE by testing to
  see what the reported active window was. First I found window IDs with

      xwininfo | grep -i 'window id'

  Then, when the bug occurred, I attempted to see if keystrokes were
  being passed to the active (but non-responsive) window with

      xev -id 0x123456 | grep Key

  I also did the same for the background window that was actually
  responding to the keystrokes. It seems that the active (but non-
  responsive) window was indeed receiving keystrokes, and the other one
  was not, although it was responding to them.. I presume that it's
  Firefox hijacking the active window internally.

  I don't see this in any other application, except much more frequently
  in Thunderbird.

  
  I've filed a bug for Thunderbird too.
