I updated to Windows 7 about a week ago. For the first few days, Facebook site was working fine. Now I cannot login ... it throws an error telling me that I don't have cookies enabled in my browser (even though I do). What I have tried: -- running "IE8 with addons disabled" (this works) -- configuring IE8 so that all known addons are disabled (this doesn't work) -- using https://www.facebook.com instead of http://www.facebook.com (this works) -- uninstalling and reinstalling Java, Flash, Shockware, etc (none of this made any difference) -- full virus/malware scans with both AVG (licensed version) and Malwarebytes (didn't find anything) -- clearing caches, temp files, etc (made no difference) I don't understand why disabling all the addons in IE8 is not the same as running IE8 with the switch that tells it not to load any addons ... however there obviously is a difference in this case. The only conclusion I can reach at this point is that there is some other piece of software intefering with IE8, but only when its using HTTP and not HTTPS. Any suggestions as to where to look next? I saw someone in another thread had an issue with a "DivX Web Player" and when I get home I will have a look for applications similar to that and will try uninstalling them if I find any.
