Good stuff timar - this definitely beats my trick of hitting the Esc key at just the right moment to stop JS from loading. I've gotten very good at that, but also life is very short and I shouldn't need to! So your bookmarklet will come to the rescue :)

Could this be integrated with Firefox's Reader mode somehow?

Not very familiar with firefox or reader mode. But if it's something firefox does with the html of the website youre currently on. Than I see no reason why it couldn't work together. First getting the article with Readium, secondly starting Reader mode.
