How a browser handles a PDF file depends on a combination of things.

1.) HTTP Headers

If you want the file to be treated as a file, vs. a "page" to load in the browser ensure you set the content-disposition to attachment and provide a filename with an extension ( with no spaces Firefox gets hung up on this) HTTP Content-Disposition Docs eg

Content-Disposition: attachment; filename="filename.pdf"

2.) New Tab/new window

If you want your content to be loaded in another tab/window, you'll want to set the target attribute of your form/link to _blank .

3.) Browser settings

If the browser has a plugin installed (eg Adobe Acrobat) to handle PDFs, there are configurations in Acrobat to determine if the app opens PDFs separately in the application... or "embedded" in the browser. Note that modern browsers (Chrome/Firefox/etc.) also have their own built in PDF rendering without a need for a plugin.
