Based on Aardvark; fixes the web.

    javascript:for(var a=document.querySelectorAll('*'),i=0,e; e=a[i]; i++) if (e.currentStyle.position == 'fixed') e.style.position = 'static'; void(0)

edit: I just see a bunch of others also made bookmarklets to remove elements, so I added a bit more description as to why mine is different. Setting all position:fixed elements to position:static really does seem to do exactly what you want in one fell swoop, in 99% of the cases.

Even plain text pages aren't immune from the Javascript curse. I've said this before, but Google's blogger/blogspot service is one of the worst offenders. For example, here is the official Android blog from Google

http://officialandroid.blogspot.co.uk/

With Javascript disabled, nothing loads at all. When Javascript is enabled, you get a mostly text page that could easily be served without Javascript.

Maybe some kind of balance would be better than a block list. Effective ads that don't annoy.

(though I think it strips out the junk after the whole page loads.)
