I run code from the question in the local machine and take this error:

Not allowed to navigate top frame to data URL: data:application/pdf;filename=generated.pdf;base64,...

JsPDF - Not allowed to navigate top frame to data URL

I tried the suggestion @WeihuiGuo. Unfortunately for me.

I found than Chrome automaticaly open pdf.

And not only for the new tab. Not opened on the current page too.

In other browsers this page display correctly.

Such sad news.

You're generating a PDF from its raw data using Javascript. Why not use a reader like Adobe to render it? That is what is happening when you are clicking the link from the console. You could literally just open the link and it will open as a PDF. I think you are possibly over complicating this task.

Try window.open() instead. The following code worked for me. You will need to modify the window/page size.
```
let dataSrc = pdf.output("datauristring");
let win = window.open("", "myWindow");
win.document.write("<html><head><title>jsPDF</title></head><body><embed src=" + 
    dataSrc + "></embed></body></html>");
```
Update:

Didn't realize that jsPDF comes with a built-in method pdf.output('dataurlnewwindow');, which uses iframe,

The downside of pdf.output('dataurlnewwindow') is that it opens a new tab/window with datauristring as the pdf file name and the download button doesn't work, while window.open(pdf.output('bloburl')) seems fine with the download button.

Okay, pdf file can be renamed like this:
```
pdf.setProperties({
    title: "jsPDF sample"
});
```
Update 2:

To avoid the page being cut off when a page is zoomed, you can set the html2canvas scale accordingly.

It's actually very easy, don't complicate things..
```
window.open(URL.createObjectURL(doc.output("blob")))
```
or a more verbose and less efficient version:
```
let newWindow = window.open('/');
fetch(doc.output('datauristring')).then(res => res.blob()).then(blob => {
    newWindow.location = URL.createObjectURL(blob);
})
```
(You need to open the new window immediately after the onclick or Chrome will block the popup. This solution is not as good because there is an unnecessary conversion from datauri to blob)

This code works for me

  var doc = new jsPDF();
  doc.setProperties({
  title: "new Report"
  });
  doc.output('dataurlnewwindow');
