I generate an SVG string in JavaScript.

I serve it to the user with:

window.open("data:image/svg+xml," + svg_xml_string);

When you try to save that page in Chrome it will suggest to save as download.svg is there anyway I can change the default filename of the download?

I tried:

data:image/svg+xml;headers=Content-Disposition%3Aattachment%3Bfilename%3D%22suggest.svg%22,...

But it doesn't work.

This is solved in some, very new browsers. The question linked in the comments also mentions the Opera-specific proposed extension you brought up, but I think your best bet is to use the <a download="..."> attribute and suggest that users with older browsers set the filename for themselves when downloading.
