xTimes by Ari Cooper-Davis

This add on allows you to download Cryptic Crosswords from The Times website in .ipuz format. When you are on a page containing such a puzzle the add-on icon will go green and you can click it to download the puzzle. Note that this doesn't circumvent the need for a subscription to The Times, and nor should it, it just enables you to download the puzzle for completing offline in a more accessible format than PDF.

This is an open source add-on, and I am an amateur coder, so please help contribute your code and expertise if you can.
