Sandboxie & Appguard: What a combo! Thanks to this great post I got them both to be nice to each other. Thanks guys! Firefox(Nightly) and Chromium work without a hitch in Appguard's Lockdown mode. I thought the only thing missing from Appguard was a decent virtual environment or a decent firewall and there's where sandboxie comes in. I've run many leaktests in Appguard and the only ones that come back as failed is because there is no way to stop those programs from accessing the internet. This combo should work nicely.
