I would also like to be able to bookmark a page along with saving its contents entirely as a snapshot (the text of the page, a screenshot of the page, a PDF of the page, or all of the above) in some standard format. That way I can do a full-text search through my past tabs or bookmarks to find what I am looking for, and look at it again, even if the site is presently inaccessible. Is there anything that does that? Or any software that can automatically do that for all the bookmarks I've accumulated (especially those behind logins)?
