I have a bookmarklet for that
unfortunately it won't let me post it as a link, so here's the source
www.canazza.co.uk/b3taHideNSFW.js
the bookmarklet code is in the comment at the top. It searches for NSFW tags and then hides all iframes, images,objects and embeds in the related post.
you have to click it each time, but it works.
