Epic Privacy Browser Forums

I've been using Firefox which works fine. With Epic, I get a 'resolving host' message and either the page won't load or takes 2-3 minutes to load. I'm told I should flush the dns cache but I don't see how to do that. I've had a similar problem with Chrome but it's not nearly as bad.
E.g. just tried www.cnn.com:

Firefox: about 4 seconds
Chrome about 2 minutes
Epic: Timed out after 30 seconds.

Any ideas how to fix this?
