I use Windows Firewall with Advanced Settings and I don't know enable connection for PortableApps browsers.
I use task manager to find the exe browser (FirefoxPortable/App/Firefox64/firefox.exe, OperaPortable/App/Opera/46.0.2597.32/opera.exe or K-MeleonPortable/App/K-Meleon/k-meleon.exe) and I create a rule to allow this exe to connect to HPPT & HTTPS (TCP 80 & 443) like a resident browser. But it can't connect.
I think that PortableApps browers use a Windows service to connect, but which one ?
How can I do to allow PortableApps browers to access internet without a general rule to allow TCP ports 80 & 443 ?
PS : Sorry for my bad english.
