Firefox - website takes me to new tab automatically and I cannot stop it

So I have a website where I can select links and click a button to open them all at the same time. When I do that Firefox takes me to one of the newly opened links automatically.
I wanted to stop this behavior, so I looked and looked, and eventually found this option:
browser.tabs.loadDivertedInBackground
Now, when I set this to true, newly opened tabs never automatically take me to them. So if I click an ad on a site that normally opens in a new tab and takes me to it, now it doesn't happen. I also tried this code:
<p><a href="#" onclick="window.open('http://google.com');
window.open('http://yahoo.com');">Click to open Google and Yahoo</a></p>
This code opens 2 links at the same time. I was thinking maybe opening multiple links at the same time somehow overrides Firefox. But no, the links opened and I was not automatically taken to any of the new tabs.
Also must be said that I'm having this problem in Firefox 75 and 74. But when I try it in Firefox 55.0.2, I don't have the problem. In Firefox 55.0.2 the "browser.tabs.loadDivertedInBackground" actually works even on the website where I have the problem (I can't share the site because it's behind login).
This appears to be the code responsible to open multiple links on the website I have an issue with:
$(document).on('click', '.statbtn', function () {
var me = $(this);
var isAnyRowSelected = false;
$('.row-checkbox').each(function () {
var t = $(this);
if (t.is(':checked')) {
isAnyRowSelected = true;
$('select[name="status[' + t.val() + ']"]').val(me.attr('id'));
}
});
if(isAnyRowSelected == false){
bootbox.alert("No Orders Selected");
}
});
$(document).on('click', '.openlink', function () {
var me = $(this);
var isAnyRowSelected = false;
$($('.row-checkbox').get()).each(function () {
var t = $(this);
if (t.is(':checked')) {
isAnyRowSelected = true;
console.log();
var win = window.open(t.data('link'), '_blank');
if (win) {
win.focus();
} else {
bootbox.alert('Please allow popups for this website');
}
}
});
So I tried everything I could think of. Many changes to the about:config, restarting my browser, unticking the "When you open a link in a new tab, switch to it immediately" option in Firefox. But nothing works. When I open links from this one site using this specific button, I always get automatically taken to one of the newly opened tabs.
Here is a similar-ish problem - https://www.reddit.com/r/firefox/comments/bnu6qq/opening_new_tab_problem/
Any ideas why this happens and how to fix it? I mean, a website shouldn't be able or allowed to override Firefoxe's native setting, right?

Okay, because I don't wanna be an ass, here is the solution.
$(document).on('click', '.statbtn', function () {
var me = $(this);
var isAnyRowSelected = false;
$('.row-checkbox').each(function () {
var t = $(this);
if (t.is(':checked')) {
isAnyRowSelected = true;
$('select[name="status[' + t.val() + ']"]').val(me.attr('id'));
}
});
if(isAnyRowSelected == false){
bootbox.alert("No Orders Selected");
}
});
$(document).on('click', '.openlink', function () {
var me = $(this);
var isAnyRowSelected = false;
$($('.row-checkbox').get().reverse()).each(function () {
var t = $(this);
if (t.is(':checked')) {
isAnyRowSelected = true;
console.log();
// var win = window.open(t.data('link'), '_blank');
setTimeout(() => window.open(t.data('link'), '_blank'),1000);
// if (win) {
// win.focus();
// } else {
// bootbox.alert('Please allow popups for this website');
// }
}
});
if(isAnyRowSelected == false){
bootbox.alert("No Orders Selected");
}
});
Basically, adding a "setTimeout" fixed it. For some reason Firefox needed the delay to process things correctly, I guess, I think. Before the delay, the actions would happen instantly, and I'll just guess that Firefox couldn't "catch up" to it in order to apply the exemption of not navigating to new tabs. But a timeout delay fixed it.
And for anyone that may run into this with a similar issue, it also required an edit in Firefox in "about:config" to set this to True.
browser.tabs.loadDivertedInBackground
That's all folks :)

How to go to a specific tab with Firefox Extension

I'm creating a Firefox Extension. It opens a new tab and then closes it a moment later. When the new tab closes, I want to go back to the original tab I was on, NOT the rightmost tab. This is what I have so far and it always goes to the rightmost.
function openNewTab(tabs) {
let tab = tabs[0];
browser.tabs.create({"url": tab.url});
}
function closeTab(tabs) {
let tab = tabs[0];
browser.tabs.remove(tab.id);
}
function onError(err){
console.error(err);
}
function openAndClose() {
var mytab = browser.tabs.query({currentWindow: true, active: true}).then(openNewTab, onError);
setTimeout(function () {
var closeIt = browser.tabs.query({currentWindow: true, active: true}).then(closeTab, onError);
}, 1000);
}
browser.browserAction.onClicked.addListener(openAndClose);
Given a tab id, or tab index, how do I activate, or go to that specific tab?

You want the window & tab update functions. You can disregard focusing the window as long as you keep focus of the window when you create your new tab. (As currently shown in your code sample)
https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/windows/update
https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/tabs/update
browser.tabs.query({}, function(tabs) {
for (var i=tabs.length-1; i>=0; i--) {
if (tabs[i].id == myTabID) {
browser.windows.update(tabs[i].windowId, {focused: true}); //focus window
browser.tabs.update(tabs[i].id, {active: true}); //focus tab
break;
}
}
});

JS: Erroneous popstate event when trying to navigate back past the initial page load

I'm trying to implement JS history using pushState/popState. Navigating back and forward works just fine, but I have trouble navigating before the initial page load using the browser's back button. It needs 1 extra hit on the browser's back button to leave the page. Why is that?
function action(text) {
history.pushState({"text":text}, text);
doAction(text);
}
function doAction(text) {
$('span').text(text);
}
var $button = $('button');
var $p = $('p');
$p.hide();
action("foo");
$button.on('click', function(){
action("bar");
$button.hide();
$p.show();
})
window.addEventListener("popstate", function(e) {
if (e.state !== null) {
$button.show();
$p.text("Next back should navigate away from this page");
} else {
$p.text("Still here? Why is that? Next back will really navigate away");
}
});

Edit: Tested with Chrome OS/X

The initial page load shouldn't use history.pushState because it would add another history entry. There is alredy an implicit first history item with state null.
Using history.replaceState for the initial page load, sets a state for that item but doesn't add another one.
var initialPageLoad = true;
function action(text) {
if (initialPageLoad) {
// replace the state of the first (implicit) item
history.replaceState({"text":text}, text);
} else {
// add new history item
history.pushState({"text":text}, text);
}
initialPageLoad = false;
doAction(text);
}
function doAction(text) {
$('span').text(text);
}
var $button = $('button');
var $p = $('p');
$p.hide();
action("foo");
$button.on('click', function(){
action("bar");
$button.hide();
$p.show();
})
window.addEventListener("popstate", function(e) {
if (e.state !== null) {
$button.show();
$p.text("Next back should navigate away from this page");
// } else {
// won't happen anymore, as the first item has state now
// $p.text("Still here? Why is that? Next back will really navigate away");
}
});

Capture the browser window (only) close event

var inFormOrLink;
$('a').on('click', function () { inFormOrLink = true; });
$('form').on('submit', function () { inFormOrLink = true; });
$(window).on('beforeunload', function (eventObject) {
var returnValue = undefined;
if (!inFormOrLink) {
returnValue = "Do you really want to close?";
}
if (returnValue != undefined) {
eventObject.returnValue = returnValue;
return returnValue;
}
});
Ref : Browser close event
I tried to execute the above mentioned code in Chrome Version 65.0.3325.181
it is working properly i.e popup does not open while redirecting or submitting form,
i want to show popup only when user close the tab, sometimes browser shows the popup but sometimes tab gets closed without showing popup.
I don't know why it is happening.

Calling Javascript function on browser close

I have a site, now what I want is when user switch to some external site, then an Ad should be popped up, and also when user close the browser window, the Ad should get popup, I have used onunload, but it shows the message on clicking every link, and also I used on beforeunload, it does almost everything, but it do the same as onunload...
Please anyone have some idea how should I achieve this?

This doesn't prevent popup appearing on page refresh, but does this job as requested:
<script>
var isLinkClicked = false;
// Either plain JS solution:
var links = document.getElementsByTagName('a');
var l=links.length;
while (l--) {
links[l].addEventListener("click", function() {
isLinkClicked = true;
}, false);
}
// Or jQuery solution:
$("a").live("click", function() {
isLinkClicked = true;
});
// And then Unload event listener:
window.addEventListener("unload", function(evt) {
if (isLinkClicked) {
isLinkClicked = false;
return false;
}
// here comes the rest of the code
}, false);
</script>
