session restore of firefox

I  would like to be able to take the contents of the screen produced
by firefox with the warning message "well, this  is embarassing"
and save it somehow.

This function of firefox represents a kind of memory for the user
who wants to keep the restore-session screen content (urls).

  As it is
now firefox user can stack up this tab and start browsing with new
tabs. Next day will do the same but then there is a lot of urls to
re-load and short-out.
