I have VPN on with Split Tunnel turned on and the browser Firefox excluded. Most of the websites I try on Firefox don't work. For example Walmart and Lowes don't load and Firefox says "Problem loading page - Secure connection failed". If I turn VPN off or remove it from the exclusion list, it works just fine. If Firefox is excluded it should operate normally as if the VPN is not turned on at all, right? This does not appear to be the case. Any ideas? Thanks.
