In FF 3.6 when I 'quit' from the file menu all opened tabs were
automatically stored and reopened when FF restarted.
If I exited using the 'X' button, I was asked if I wanted to save
all tabs on restart.
Under FF 4.0, when I 'quit' or exit with 'X' I loose all my tabs on restart.
I've searched thru the preference menu under the 'Edit' menu,
and I've looked thru every setting under the Tab Mixed Plus extension.
There has to be a simple setting I'm missing.
Can someone point me in the right direction on this.
