I recently switched servers from ATT to Comcast. After reloading Firefox 3.6 I found that my home page would not fully load. Lines and pics were inclomplete with no background. As soon as I went to a website, I got a cirtificate error and then another and another. Every site I go to I get the same error and have to make an exception to enter it. Then it doesn't load completely. I have NO problems using "IE" but would rather not go that way. Comcast Tech support cannot answer the why question or any help to fix this.
