Yes I know that extension..
But my purpose is different, for researching and education , there are pages that only exist in the internet archive, and so I do not want to search the same thing two times in two different places..
Yeah but if the site issues a 404, you simply right click and the extension will show you the archived copy. Sadly many sites fail to provide a decent 404 page if a resource doesn't exist, they just do redirect spamming or in the worst case: 503 error[0]
