Upon further research I found it was due to a recent update of RealPlayer which included downloading Google Chrome. I did not want Google Chrome so deleted it, but did not realize it had modified my registry as default internet browser. I had to go into Internet Options and modify default Internet browser to IE and then now everything is working properly again.
Hi. This is dreamsicle. Had the same issue. I was having problem opening links in comcast/xfinity's homepage and any of their pages/links such as help page. Had trouble opening links in other websites also such as school sites. Had trouble opening links in my emails such as crazy coupon lady.
Since I have been exchanging private messages to comcastjoe, he had suggested changing my internet browser. I downloaded google chrome and made it my default browser and everything seems to be working fine now. I access my email by going to xfinity but through google chrome.
So, I don't know whether that meant the problem was comcast/xfinity or internet explorer. If it is comcast, I hope they'll do some kind of reimbursement for all that problem we had to put up with and some of us dealing with it for a month or more now.
