Sorry for slightly cross-posting... So near, and yet so far, I've installed Fennec. Then, I've gone into about:config and added: "general.useragent.override" = "Mozilla/5.0 (Macintosh; Intel Mac OS X x.y; rv:10.0.1) Gecko/20100101 Firefox/10.0.1" Now, going to read.amazon.com, I get my list of books (yay!) but it doesn't seem that Fennec is giving the local storage needed to download and read a boo (boo). (I get the 'Error Opening Content' error message) Darn...
