I’m using Comodo (for the moment) with the McAfee proxy (part of their security center 7).
Many web pages work fine, but the following pages give me a blank page in Firefox and an error message in IE (page cannot be found, followed by it trying to load from my home page, which is ‘about:blank’):
http://filext.com/ and http://groups.yahoo.com/
If I set Comodo to pass all, things work (in both Firefox and IE6)
If I turn off the McAfee proxy, (with Comodo set to normal) things work.
Nothing odd showing in the log.
