Replying to NS is not fully loading

Ok, so NS isn't fully loading. When it does, it takes a good 10 minutes to do so. This doesn't bother me until I have to post since the posting box only appears on my firefox browser until after everything is loaded. It gets stuckk on m1.2mdn.net and a ad.doubleclick.net. Right now I'm on my Opera browser, which doesn't get the full WYSIWYG posting box apparently, but it posts and loads fine. It's just my firefox broser that's having the problem. Thanks.
