Since webkitgtk Version 2.4.2 in ArchLinux some pages can't be open. The page will be relaoded but there is no page shown or an error appears that the page co not shown. I'm currently at work so i can't give you more or detailed information currently. But i think the important things are stated in the linked ArchLinux Bug Post.
This is fixed with webkitgtk-2.4.3-2 on ArchLinux.
