since the slow loading issues were resolved: using the default browser UI — every time i open dbzer0 in a new tab in Firefox — the page will appear as if i'm signed out.
i can fix this by hard refreshing, except on /posts. if i open a /post in a tab where i appear signed in, it loads correctly.
sometimes this happens on the subscribed feed page, where i seem signed out but i see someone else's subscriptions, but with my votes indicated. when i'm stuck like this, /unread_count is still polled for my account.
