Recently, I have been getting a “Firefox can’t find the server at …” while surfing the net. I recognized this as a DNS problem, as I used to get that message on some of my PCs. On my PCs, I switched to using OpenDNS years ago, and that solved the problem. I don’t know why this problem just started on my MacBook Pro, but I decided to do the same thing.
