mozilla can't get external web

[Pavel Kovalenko]

Can anybody help with problem? after installing nvidia driver, and
reinstalling X-libs mozilla tries to get it's default page and tcpdump
shows no packets on interface, but "links -g www.mozilla.org" works fine.
File resolv.conf also fine with all network services.
What's wrong with mozilla? There is no problem with local apache, and on
remote X this mozilla also can get to any site.
I used standard installation from /usr/ports/www/mozilla.
