I am presently having problems when using Facebook. It happens rather frequently that I am unable to load FB and I always get the following message: "Your access to Facebook is being blocked or redirected by a third party. Please check with your ISP provider." What I did to gain access to FB is to add "s" to the http address, i.e. https:// .... It worked sometimes but I don't think that this will solve the problem in the long run. Both my son and I log-in to Facebook daily on my iMac. Is it because of this that I am facing this problem? I have already checked with our internet provider and they confirmed that there is no problem with the internet. I have tried to delete the cookies but the same problem persists. Each time this happens, I will delete all cookies again. The irony of things is that we could gain access to FB without any problems by using our other two computers at home sharing the same internet line. Anybody out there who can help me? We would be very grateful for any solution. Thank you in advance.
