How would a web designer be able to choose my intention prematurely without a crystal ball? Not to mention download support in browsers got WORSE over the year

How would a web designer be able to choose my intention prematurely without a crystal ball? Not to mention download support in browsers got WORSE over the years. All major browsers (but especially Google Chrome with its "never ask, just do it" UI attitude) need a good download manager. I strongly prefer "save as..." over the mess that the Chrome default download behaviour is.
