Comment 203 for bug 438868

Yep,

noticed the return of the problems, too. Firefox 5.0 very often loses keyboard focus if I have more than one Firefox window opened (no matter how many tabs I opened within the windows).

Interestingly, the problems are now more grave than before. When I lose the keyboard focus, the old tricks do not work anymore. When I change to another virtual desktop/workspace and then change back to the one on which I have opened the window the problem still exists and I still have no focus.

Btw.: I noticed a second before that I do not only lose the keyboard focus, but also I cannot click on any flash video (like, for instance, those on youtube). There is no reaction to mouseclicks.

There are only two possible workaround to regain keyboard focus (or a correctly working Firefox Window ):

1) Close Firefox completely and then reopen the windows. So I let sessionmanger handle this and I have to hope that all windows, on which I had been working, will open correctly.

2) The second solution is somewhat strange. I can open a new Firefox window, in addition to those which I have already opened. This new window will -- certainly -- get the keyboard focus. But then I can change to the original Firefox window which displayed the focus issues and there the keyboard focus works again as well.

It should be said that in all cases I recently encountered I lost the focus in ONE of the Firefox windows not in all of them. So I was able to type into window A (no matter in which tab is was working) but somehow Firefox windows B lost its keyboard focus and later one it won't regain the focus.
