We have an application that pulls URLs from configuration and creates buttons for such user defined URLs. Because we are in a console navigation environment, every time these URLs are internal, instead of opening a new browser tab, it creates a console sub-tab.

enter image description here

Initially I thought it was great, but noticed many of the pages are not optimized to finalize under a console tab (return URLs and redirects break the tab on finish) so now I'm wanting all pages to open in a new browser tab. Currently invoking a redirect NavigationMixin.Navigate which works fine for externally hosted pages. Is there a way to change this behavior for same domain pages? The premise is that I can't touch the destination pages at all, just the page with the buttons in the console.

        if (this.tilePageRegion==='New Tab'){ // open new tab
                    type: 'standard__webPage',
                    attributes: {
                        url: this.tileUrl
        }else {
            location.href = this.tileUrl; //Same page replaces full page

if you want new browser tab, you should not really use NavigationMixin - it will simply add the url to current url as it takes it as partial url (bug). So, instead you can use window.open directly:

if (this.tilePageRegion === 'New Tab') {
    window.open(this.tileUrl, '_blank');

  • TY, worked as stated! I'm not sure why I was confusing DOM containment for "document" and "window" (only query LWC restrictions) with other operations using those two objects. I was also misled by the LWC documentation on navigation and best practices because it states to use 'lightning/navigation' developer.salesforce.com/docs/component-library/bundle/… – Glen De Marcos Sep 10 '19 at 5:26
  • In Aura or LWC you have access to window and document, but only that they are secure versions and only limited methods on them are exposed - so you can use those exposed methods on secure window/document objects – salesforce-sas Sep 10 '19 at 5:30
