If possible I would like to have at least one method that is the same for all browsers rather than different instructions for each browser.
There really isn't one method that'd do that. Not all browser are able to display/preview atom/rss feeds correctly/on their own.
You might find a download manager that supports most of the major dozen or so browsers.
Not all feeds will have their entire history cached in GReader if nobody subscribed to them early enough,
so the only way would be to view the pages themselves - with the exception of Blogger-based blogs, where you could add ?max-results=500
to the end of the feed URL to display the 500 newest posts.
Of course, you could just not use a browser at all, instead use a proper web crawler such as wget or HTTrack.
