How can i change default webviewer?

I have an application that displays the page in the default browser and my question is whether it is possible to set the Webviewer to display the page on Opera or Chrome because in the standard one, uploading files to the page does not work. The point is that the page should be displayed in Webviewer on the script of Opera, Firefox or chrome ...

Sounds like what you need is an extension that will allow you to upload files in a webviewer
