I use the DNS flusher addon in Firefox, and with the Status-4-evar toolbar addon, I can see the IP address of the sites I visit. My provider (not in Finland) offers IPv6 support, and I see IPv6 addresses quite often, especially for Google, Facebook and other big sites.

This addon makes IPv6 real for me. I know my provider uses IPv6, but actually seeing this address makes a difference to me. Most people don't know and don't care, and they shouldn't as normal user, but for me it's different.
