@joepie91_: Just FYI, documents do not load until you accept the site's cookies. I don't know of a technical reason why this should be, off the top of my head, so if there isn't one, you may consider removing that restriction/requirement.
Can you tell me what the name of the offending cookie is?
I have vague recollections about Chromium and/or Firefox confounding localStorage with cookies when it comes to allowing or denying.
