There is a 3 step workaround you can do this by

• You should know when the popup will be opened. Popups are blocked in chrome by default. But chrome will show a popup blocked notification in bottom right corner.
• click on notification to select always accept popup from this specific site
• Reload the main (parent) page. This will load the popup in small windows. Right click in titlebar of popup window and select "Show As Tab". Once popup is transformed in a window with tab, you can drag it back to main window.

Hope this helps.

Thanks.

Turn pop-ups on or off

• On your computer, open Chrome.
• At the top right, click More. Settings.
• At the bottom, click Advanced.
• Under 'Privacy and security', click Site settings.
• Click Pop-ups and redirects.
• At the top, turn the setting to Allowed or Blocked.

On programmatically open new window and not new tab, you can do it via JQuery:

<script type="text/javascript">
$(document).ready(fncOpenNewWindow);

function fncOpenNewWindow() {
        $('#testURL').unbind();
        $('#testURL').on('click', function () {
            window.open("", 'Window Name', "height=200,width=200,modal=yes,alwaysRaised=yes");
        });
    }
</script>

This is the control:

<a href="@Url.Action("Action", "Controller")" id="testURL">Click Me</a>

This is tested on Chrome. I haven't tested this on other browser but this should work fine with Chrome.

Ideally, the feature you are looking for in Edge to open a new tab is currently not available

LOLWUT

A popular feature which was a common, top-level setting in IE, and which has existed in both Chrome and Firefox for many years, was intentionally not imported into Edge's feature set?  Who made that decision?  This is why people continue to use non-MS browsers in the majority.

C'mon Microsoft, free tip from a Systems Engineer: don't remove/drop features that are very popular with users.  This is requirements capture 101.

I have figured out a fix to this using Firefox 58.0.2. Firefox 59 slightly breaks this functionality - it opens as a new window in a new macOS space instead of a floating popup.

I don't have fixes for Chrome and Safari or Firefox 59, but I am certain they are possible.

(If you require Firefox 58.0.2, you can find it on Mozilla's FTP here. You will likely want to disable Firefox auto-updates, but this will compromise your security in the long run.)

In the address bar, type in about:config and hit enter.

On the warning page, click "I accept the risk". As long as you don't mess with other settings, your browser should remain safe.

In the search field, type link. - this will help us narrow down to the two settings we want to change.

Double click on browser.link.open_newwindow.disabled_in_fullscreen to set the boolean to false.

Double click on browser.link.open_newwindow.restriction and set 1 as the value and click OK.

This should force Firefox to open popups like the one you have as a new window that floats on top of the fullscreen window. Again, if you use Firefox 59, the popup will make a new window, but it will go to a new space instead of floating.

window.open must be called within a callback which is triggered by a user action (example onclick) for the page to open in a new tab instead of a window.

Example:

$("a.runReport").click(function(evt) {
    // open a popup within the click handler
    // this should open in a new tab
    var popup = window.open("about:blank", "myPopup");

    //do some ajax calls
    $.get("/run/the/report", function(result) {
        // now write to the popup
        popup.document.write(result.page_content);

        // or change the location
        // popup.location = 'someOtherPage.html';
    });
});
