UnMHT allows you to view MHT (MHTML) web archive format files, and save complete web pages, including text and graphics, into a single MHT file in Firefox/SeaMonkey.
This Firefox/SeaMonkey extension will allow you to save a website, such as a tumblr post with a bunch of links on it, to a single file. Personally I’d recommend finding a reblog with a simple theme on their blog so it’s less of a hassle to load.
So you can just save stuff like masterposts, political research, or playlists and easily be able to bring it back up without internet & without having to search your blog.
Although FYI, it seems tumblr is using redirects in all of the links posted on this site, but the actual URLs for links are included (you just have to convert over some HTML code to characters, such as / to / ). http://www.url-encode-decode.com/ can de-code such URLs.
