Safari6Lion.pkg
that's what happened to me, low-experienced Apple user since, dunno, 2002 or so.
downloaded Safari 6.1.1. today (that's what i get now under properties when ctrl-clicking safari.app in the folder applications)
tried to use the site elsteronline.de
Safari crashed, only way seems to be force quit by ctrl-clicking the application
always insists on reopening all windows from last session
then
https://discussions.apple.com/thread/4135165?start=15&tstart=0
gives me something which I didn't use, because i don't understand it
so what i finally do now is that i'm very glad i still have an old version of firefox on my computer (and no other browser at all left), so i write this here, wait for the next update to Safari and hope that that will do the trick.
otherwise i'll try other browsers.
