You need to use the name attribute:
window.open("https://www.youraddress.com","_self")
Edit: Url should be prepended with protocol. Without it tries to open relative url. Tested in Chrome 59, Firefox 54 and IE 11.

Specify window "features" to the open call:
window.open(url, windowName, "height=200,width=200");
When you specify a width/height, it will open it in a new window instead of a tab.
See https://developer.mozilla.org/en-US/docs/Web/API/Window.open#Position_and_size_features for all the possible features.
You don't need to use height, just make sure you use _blank, Without it, it opens in a new tab.
For a empty window:
window.open('', '_blank', 'toolbar=0,location=0,menubar=0');
For a specific URL:
window.open('http://www.google.com', '_blank', 'toolbar=0,location=0,menubar=0');
This is a trick,
function openInNewTab(url) {
window.open(url, '_blank').focus();
}
// Or just
window.open(url, '_blank').focus();
In most cases, this should happen directly in the onclick handler for the link to prevent pop-up blockers, and the default "new window" behavior. You could do it this way, or by adding an event listener to your DOM object.
<div onclick="openInNewTab('www.test.com');">Something To Click On</div>
Reference: Open a URL in a new tab using JavaScript
Nothing an author can do can choose to open in a new tab instead of a new window; it is a user preference. (Note that the default user preference in most browsers is for new tabs, so a trivial test on a browser where that preference hasn't been changed will not demonstrate this.)
CSS3 proposed target-new, but the specification was abandoned.
The reverse is not true; by specifying certain window features for the window in the third argument of window.open(), you can trigger a new window when the preference is for tabs.
As confirmed in both: source1 source2
there isn't a function that works throughout all browsers. There are options for popups, but this isn't a good idea as many use popup blockers.
To reiterate the first source, it's a browser setting for each user to decide to open a new tab in the background, or not. And because users decide this in their browser settings you will get inconsistent experiences.
Try following may be helpful
<button id="open">open</button>
document.getElementById('open').onclick = function() {
window.open('http://google.com');
};
Note: You can't open tabs in the background using javascript because this is set in the user's preferences in about:config, which you have no control over. The setting in about:config in Firefox is:
It is only possible if you will be generate the Click event with Already Pressed Control Key Dynamically.
e.g. Ctrl + Click will always open new tab and stay you on current tab.
browser.tabs.loadDivertedInBackground=true
