Get rid of 'This tab has crashed'
Firefox keeps opening with---'Bad news first:This tab has crashed'. It is easy to work around and proceed but i do not need it.

Are you closing Firefox at the end of a computer use session? Or are you just turning off the computer with Firefox still running? If the latter, stop doing that - close Firefox first.
