i love the new Safari 5 'Reader' feature, but Safari is not my main browser. I mostly use Chrome, and sometimes Firefox. Does anybody know if there's an extension that does the same? I've been using Arc90's Readability, which is very nice, but isn't quite the same (it doesn't do multi-page, for instance).
I think you can try a combination of Readability and AutoPagerize to make that happen. AP first, so the content is all loaded, and then Readability to get it displayed nicely.
P.S. For a lot of sites, you can click through to the "Print" view and then enable Readability on that, as the "Print" view is often the full article/post.
Readability is a simple tool that makes reading on the Web more enjoyable by removing the cluter around what you're reading.
