windows.open() with data URI close automatically

Question

I've a html page that generate a csv with the following code:

var encodedUri = encodeURI(csvContent);
window.open('data:text/plain,' + encodedUri,'_blank').focus();

I'm using firefox in local and it generates correctly a new tab with the data in it, but with firefox or chrome, not in local, the window opens and then close almost immediately (no popup alert triggers)

how may I avoid this and get my file with no problems?

Answer 1

This is most probably due to AdBlock extension. I disabled it and that solved the issue for me.

Answer 2

Apparently one of the filter lists that uBlock Origin uses comes with a rule that unconditionally blocks any data URI popups. https://github.com/gorhill/uBlock/issues/2465
