Hi, 
 I spent a lot of time with the same issue and I finally resolved it by re-installing the CAs. Ona MAC Safari worked fine from the outset, but FF kept failing. I thought I had deleted all certificates from the XG and re-installed them correctly. After many days of frustration and help/pointers from Sachin I found a certificate that wen not trusted. I changed the trust settings and the issues no longer occur and I was able to remove number of site exceptions. I was also able to get my Wife's MAC to work with https scanning after cleaning up het machine CAs. 
 With a W10 machine I uninstalled all XG CAs and then installed the XG CA in the trusted root folder and bingo the W10 machine no longer has issues. 
 I found some of these fixes while searching for how to install CAs on W10 machines. 
 The good part is now the failing sites all load much quicker and the XG policies are applied. 
 Interesting finding during my testing is that facebook is a firewall avoidance app as well as high rating app, so had to downgrade those application settings.
