After the last update, my IBM Clone computer does not close the session of firefox when clicking on "close" it clears the screen back to the desktop but firefox continues to hang there in the backround and will not allow another session of firefox to start until the first session is closed. The only way to reconnect is to do a restart on my system, and then the old firefox session is closed and the new session will start.
