open a new browser tab in background programmatically - javascript

Problem
I'm using a web-based feed reader, TinyTinyRSS. When sifting through the feed lists, I'd like to open interesting articles in new tabs - but in the background, because I want to read them only after I went through all feed items.
TT-RSS has a shortcut key "o" to open the article in a new tab, but it opens the tab in the foreground (window.open).
The question is now: To fix TT-RSS, I need to know how to open a background tab from javascript. It'd be awesome if the solution worked across browsers (Firefox, Chrome, Opera, Safari).
I understand the privacy issue about that, but having it enabled for one certified webpage is ok.
Existing (bad) solutions
Firefox
In about:config, set browser.tabs.loadDivertedInBackground to true.
This opens all the tabs from pages in the background, which is not what I want - I want it only for the one application/website.
Chrome
Chrome has a shytab extension. Works in chrome only and is for all pages.

Back when popup ads were a thing, this was called a "popunder" window. Popunders used to do something like this:
var popupWindow = window.open(...);
popupWindow.blur();
window.focus();
Popup blocking kind of messed around with what does and doesn't work, though- your mileage may vary.

Use window.open to a tab in the background (not switch focus)

I'm using the following code to open a new tab on click of a PDF download.
The problem is the new tab becomes the main tab often before the PDF loads.
How can I make the view stay on the current window (PDF) and open the new tab but not switch to it?
Note: In Chrome and Opera they understand the HTML5 download tag so the PDF simply downloads and the current window redirects - All good! So this is only a problem on IE & Firefox.

Well, I'll advise you to read this Stackoverflow answer, which is, in a way, quite similar to yours (the purpose anyway) :
Javascript disable switches current tab functionality in browser
JS/JQuery is indeed very powerful but also have its limits. Imagine a web page always requesting and keeping focus once you've opened it. I think you would be really annoyed, among other things.
That's why browsers prevent those kind of actions. Common browsers at least. Meaning, there's no way to prevent a browser like Firefox, Chrome, IE & Co. to focus a table since it depend of user's parameters.
You'll have to find a way to workaround your problem. I can propose this answer since it seems to have worked for the other guy.

Changing browser title not blinking browser in taskbar

There are a lot of tutorials on how to do this, and the crux of it seems to be changing the title constantly so the browser tab or taskbar will flash, however this doesn't seem to work for me.
I can see the tab changing its title, but it doesn't flash, so I am wondering if this is something which is no longer allowed by browsers?
I am using Windows 8.1, however have also tried Windows XP
I am using Firefox 25.0.1 and Chrome 31.0.1650.57 and neither of them react how I would expect.
As an example go to:
https://rawgithub.com/heyman/jquery-titlealert/master/example/index.html
(Make sure you click the shield icon in your url bar to allow the scripts to run on that page)
Then if you click the default example button and switch tabs, I would expect the tab hosting that page to blink or flash to indicate the tab has new content, however it doesn't do that for me, although I can see the text changing constantly.
Does anyone else have this issue and know how to solve it or why it occurs? I am looking to implement a feature in a chat system where it notifies you to new messages, however for some reason the code works fine and the title changes, but the taskbar or tab do not flash or anything and the users are really wanting this feature soon.
There seems to be no information on the internet related to this so im a bit confused and came here as a last resort.
In Firefox, tab flashes when title is changed ONLY if it is a pinned tab.

How to get Chrome to open multiple sites in a new tab

I'm developing a tool that lets you open multiple pages at once with a shortcut, to be used for things like opening your daily sites or querying multiple search engines for a phrase. In Firefox, Internet Explorer and Opera, assuming you've unblocked pop-ups for the domain, the code works as expected.
Chrome, however, opens the sites in new windows instead of tabs if the links are opened automatically when the page loads. If openAll() is commented out and the button is clicked or a key is pressed, the pages open in tabs. Note it's calling the exact same function.
The best solution I've found (which isn't saying much) is the One Window extension. It works, but you can see the new window open then get sucked back in, and it keeps you from opening new Windows with Ctrl-N, forcing you to drag tabs out to use another Chrome window.
I can understand there not being a programmatic way to change this because it's a browser setting, but as a user of the tool it's annoying to have the sites all open in new windows. Is there a Chrome setting or extension that will open links in tabs when they're loaded without user input? I realize opening a bevy of windows is the very thing browsers aim to stop, but this is one time where I want to allow it.
<input id="openAllBtn" type="button" value="Open all links"> (Or press any key)
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.6.1.min.js"></script>
<script type="text/javascript">
function openAll() {
window.open('http://yahoo.com/');
window.location.replace('http://www.bing.com/');
return false;
}
$(document).ready(function() {
$(document).bind('keypress', openAll);
$("#openAllBtn").bind("click", openAll);
openAll();
});
</script>
Here's a Fiddle of the code: http://jsfiddle.net/sfzjR/
Is there a Chrome setting or extension
that will open links in tabs when
they're loaded without user input?
Check out the create method in the chrome extension docs. By default it will open a new tab, you can optionally specify the window you want that tab to open in, and give the tab a url.

Open a chrome tab from delayed javascript window.open

When I window.open("http://blarg") in chrome, I get a new tab. If I delay the open, say using a jquery $(hrm).animate({},5e3,function(){window.open(url)); it opens the url in a new window with no status bar, etc — if I give it permission to pop-up that is.
I'm looking for a way to get the instant behavior, that is, I wish to open a URL after an animation, but still in a new tab.
I imagine I could get by with learning a way to instruct chrome to never ever open pop-ups and to always open them in tabs (I imagine there's a webkit setting, why it's not a built in is a mystery); but I'd rather try to find a way to do it from the javascript if possible.
I somewhat doubt there's any way to do this though. I'm not aware of any javascript that's tab-aware.
A similar question was asked about tabs in Firefox, but the same answer applies:
There is no way to force a window to open as a tab. It's all dependent on the user's preference settings.

Open links in new tab in Firefox

I am developing an Firefox extension. How can all the links on a webpage to be opened in a new tab?
That's usually a configurable option in Firefox to handle new links, so they may override your extension with that.
However...
The code
Example Website
will allow you to click the appearing words [Example Website], and the link will open in the current window.
The code
Example Website
Opens the link in a new window/tab.
The only mildly dodgy thing is that target is now apparently deprecated by the W3C, which means that it's generally up to the browser ( and the user's preferences) as to how (or even if) it is handled. But for people who have their preferences set accordingly - in Firefox - that should work.
I found what I was after. I wanted gbrowser.addtab(this.href).
Press Ctrl while clicking on the link on Windows. Use cmd on OSX.
