Comment 72 for bug 849624

Debitrotting this patch doesn't seem quite enough. I've done so locally but haven't succeeded in opening tabs yet. Also I do hope there is a better solution than using prefs. It does seem that using prefs is a common option, but looking at the code I'm not quite happy yet.

I think we should keep the number of options to a minimum in this patch and then add options like -import in a subsequent patch/bug.
