I just learned that the iOS 8 version of Safari does something really annoying.
If you switch to another tab, it no longer keeps that tab you switched out of active... It treats it as if you closed the tab and will reload the entire page when you switch back to it. This makes switching from Fakku to some hentai I'm browsing really annoying because every time I switch to the hentai, I have to wait for the page to reload, and every time I switch back to Fakku, I have to log in again as though I closed the window and re-opened it.
And yes I use Fakku in private mode, because I do that with all porn I view.
