You can't control, from a server based app, how a user configures his/her browser. Different browsers offer different options as far as dealing with cookies, popups, javascript, css, etc...
When you, the developer, start a project, you have to determine what your target audience is and then decide what technologies you want to use.
In a tightly controlled intranet where company policy dictates what OS and browser will be used, you're able to rely on a lot of browser specific features and configuration.
With a public site on the internet, you will either need to make your site a s simple as possible with the least amout of reliance on such things (Amazon, Google, and like do this) or you need to accept that a percentage of people who run across your site will not be able to use all the features you've written.
