Digital Inspiration has a useful tip for OpenDNS users who would like to keep using Gooooogle as the default search engine associated with the address bar.

Long story short:
about:config
keyword.url  ---> http://www.google.com/search?q=
keyword.enabled ---> true

It's interesting to note that the string in my keyword.url already pointed to Google but with different params, changing it to the simpler string actually enabled Google.

The article has similar info for IE users too.

With dd-wrt, I'd rather be using DNSMasq and not use OpenDNS...dnsmasq caches DNS lookups, so after the first lookup is done for a domain, subsequent lookups are going to be even faster than OpenDNS...
