Open link in a window using script (Google Sheet)

Question

I'm trying to create a function inside Google Script Editor that would open a link and keep getting ERROR messages

function myfunction() { browser.window.open("link");
}

Answer 1

I was looking for the same thing and found the solution below.
In this case it opens the link in the cell, that is selected when you press the button.
You could however just change the "selection" part and insert a url directly.

function openTab() {
var selection = SpreadsheetApp.getActiveSheet().getActiveCell().getValue();

var html = "<script>window.open('" + selection + "');google.script.host.close();</script>";

var userInterface = HtmlService.createHtmlOutput(html);

SpreadsheetApp.getUi().showModalDialog(userInterface, 'Open Tab');
}

They seem to have tightened security however, when I try this in Chrome, the new window is blocked by the built-in pop-up blocker. And Firefox doesn't even seem to try and open the link.
The Firefox issue might however be because I haven't logged in on my google account in Firefox and it seems to require authorization to run any scripts attached to sheets.

function openTab() {
var selection = SpreadsheetApp.getActiveSheet().getActiveCell().getValue();

var html = "<script>window.open('" + selection + "');google.script.host.close();</script>";

var userInterface = HtmlService.createHtmlOutput(html);

SpreadsheetApp.getUi().showModalDialog(userInterface, 'Open Tab');
}
