Can someone explain to me how can I open a new tab from a firefox extension, that contains HTML content from a string I have?
gBrowser.addTab, either using a data: URL, or opening and empty page then writing to its document. Info.
I think this is what you need - https://developer.mozilla.org/en/XUL/tabs#m-appendItem
I do not think this is possible:
Whether or not a page or tab opens is based on the user's preferences. If the user has tabbed browsing disabled, the new content will be in a new window and not a tab.
Each Browser tab requires a URL. So you would have to make a page, pass it the string as a query string or HTTP POST and then have that page return your string.
The other option is to use something like this.

I am using Mozilla Firefox and I am trying to figure out a way to access the content of other tabs in the same window using JavaScript and the DOM (I am open to other techniques if exist).
E.g., I want to run JavaScript code in tab1 which can find the title of some other tab. Basically I need this so that I can identify a tab which has opened due an href in my current page without using window.open method. All I want is a simple hyperlink which opens a page belonging to the same domain as the current page (the page should be opened in a new tab). Now I want to be able to access this new tab from the current tab.
Whilst you can easily open a new window using JavaScript, I'm sure that is as far as it goes. From a security point of view you wouldn't want JavaScript in one tab being able to query / access the DOM in another tab. Any site would then be able to gain access to your bank account details, etc. if both sites were opened in separate tabs.
You can access the new window/tab if it was opened with JavaScript and the page indeed is in the same domain.
You can open the window/tab like so
var win = window.open("/path_to_page");
Then you'll have to wait for the page to load before you can access e.g. the title.
win.onload = function(){ alert(win.document.title); };
You could use HTML5 cross-window messaging (archive.org link...but that's kind of cutting edge.
Even in that case, you'd probably need to hijack the <a> tag 'click' event with JavaScript and open the window yourself so that you'd have access to the new window object for posting messages.
Try setting a cookie which is accessible to any page in the same domain. On other pages, use a JavaScript timer to check if the cookie value has changed and when it has you can use its value and take an action.
It worked for me.
Well, this would not be possible, you could try
<a target="_blank" rel="opener" href="about:blank"></a>
This makes a link that opens an about:blank, this will have the same domain as the page that opened It because of the Same-Origen-policy.
I have a JavaScript application in a tab which opens if I click on a certain link on my page. If I click on the link again, I need to check if that tab is allready opened - if it is, then switch to that tab and do something, otherwise open a new tab.
Unfortunately using
var myApp = window.open("http://www.mypage.com/myapp.html", "My App");
if(myApp){
won't help me, because I can't rely on the URL, due to the fact that the URL will differ on each environment that I'm using.
How can I achieve this if I can't rely on the URL? The only thing I can check is the tab's name - it will allways be the same. How can I access the browser's tab array, please?
Thanks!
As far as I understand, you cannot access the browser's tab array (certainly not through JavaScript). This would be a security breach on the client side. You should think of each browser tab as a browser instance of it's own - unaware of any other tab.
You can track that if tab is opened already using the Cookie/Local storage.
Save the value "isOpened=true" in either Cookie or localStorage and Be sure to delete the values from the same when that tab is Closed or when user navigates to other pages using "onunload" event.
But the page you are going to open should be on the same Domain for accessing/ setting the Cookie.
Still we cannot do anything if the user opens the page by just copying the link.
as you are opening new window using javascript you can do this you can add a dummy attribute say "data-isOpend='no'" on that element
and when user click on that element you can change that attribute to "data-isOpened='yes'"and in javascript function before opening tha new window you have to check if data-isOpend=='no' then open link in new window else do nothing
(Just leaving a differenct ans here if any other dev comes here looking for solution for such prob,Just like me :) )
We can assign name to the tab while creating it
For eg.
function view_preview()
{
var abc;
if(abc!=null){
abc.close();
}
var url=some_link
abc=window.open(url,'tab_name');
}
Here, we are opening a new tab and if that tab is already opened we are 'refreshing' it.
I want to open a new tab when thru the parameter in the query string.
For an example,I have four tabs (t1, t2,t2,t4). Right now, i have implemented the code that whenever user puts http://abc.net/disc_apps.jsp#tab3, it automatically opens tab3.For that i have written a function in document.ready, so for that I need to refresh the page or have to open a new tab and then have to enter a new query string.
But, now i am trying to implement http://abc.net/disc_apps.jsp?defaultTab=tab3 functionality, where i don't have to open a new tab every time or don't have to refresh the page.
please help me as I am new to these things.
thanks in advance.

After deciphering the question and reading the comments up to three times, your concrete problem turns out to be the following:
I want to change the hash fragment in the URL when I change a tab in the UI.
Using query strings isn't the solution. They are server side and not controllable from the client side on without firing a HTTP request (or, "refreshing the page" as you call it yourself). Hash fragments are however controllable from the client side on. It's extraordinary easy as well: just use it as-is in tab links.
tab1
tab2
tab3
The webbrowser will change the hash fragment in the browser address bar by itself. I however assume that you already have a jQuery function which already shows the desired tab content when any of those links is clicked (and doesn't return false from the function!).

I have the following javascript bookmarklet which opens a new popup window with a facebook post page in side of it.
javascript:var d=document,f='http://www.facebook.com/share',l=d.location,e=encodeURIComponent,p='.php?src=bm&v=4&i=1261526047&u='+e(l.href)+'&t='+e(d.title);1;try{if (!/^(.*\.)?facebook\.[^.]*$/.test(l.host))throw(0);share_internal_bookmarklet(p)}catch(z) {a=function() {if (!window.open(f+'r'+p,'sharer','toolbar=0,status=0,resizable=1,width=626,height=436'))l.href=f+p};if (/Firefox/.test(navigator.userAgent))setTimeout(a,0);else{a()}}void(0)
I just add that code into the URL of a shortcut link in my browser and it opens the facebook post page and passes the URL and some info about the page I am on to it.
I need to do a much simpler task. I need to get the URL of the page I am on and either open a new tab or even just use the tab I am in and then open a link like this
http://mydomain.com/labs/iframe_header.php?url= PUT THE CURRENT PAGES URL RIGHT HERE
As you can see I just need to make a bookmarklet that will take the page I am on and pass it into my sites page. Can anyone help me, I don't know much javascript at all, would greatly appreciate any help.
javascript: location.href = 'http://mydomain.com/labs/iframe_header.php?url=' + escape(location.href);
This will open in a new window, which will use a new tab if your browser is set up that way:
javascript: window.open('http://mydomain.com/labs/iframe_header.php?url=' + escape(location.href));
