It doesn’t look like these can do what the OP wants to do — display a specific MIME type in Safari. Safari Extensions are triggered by web pages loading, and can inject JS or CSS, which implies that the page is already HTML-based. If Safari encounters a page whose MIME type is “application/foobar”, it’s not going to display any HTML, it’s going to download it as a file and the extension never gets to run. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
