How to open downloaded files in Chrome / Opera 15+ in default application automatically?

Question

In Firefox, we can set the following options to deal with downloaded files in Options->Application tab:

1. Ask what to do
2. Save
3. Preview in Firefox
   
4. save and use default app
5. save and use a chosen app

In opera (mine is 19.0.1326.63), for example in case of a pdf file, we can preview it in browser by an add-on that uses HTML5, but if the add-on is disabled, only way to open it is to save and manually open it.

I guess, it is same in case of Google Chrome too, as these two browsers share similar behavior.

Is there any way to save and automatically open the file, as can be done in Firefox?

Answer 1

Within Chrome you can simply select to "Always open files of this type" which automatically opens the files after they're downloaded.
