Dynamically new tabs, add a tab with a button pane

In most modern browsers, it is very easy and intuitive how to open a new tab in the same window.
Usually, there is a small button with a "+" to the right of the tabs. When you click this button, a new tab is created and it receives focus.

What is the easiest way to mimic this behavior in a JavaFX application?. I think trying to add a tab 'false' with a sign «+» Then I know when this tab is clicked, and on this event, I could dynamically create a new tab and give it focus.
What is the right way to do it? A small example of how best to implement it would be greatly appreciated.

This seems to work ok:

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Tab;
import javafx.scene.control.TabPane;
import javafx.scene.layout.AnchorPane;
import javafx.stage.Stage;

public class TabPaneWithAddButton extends Application {

  @Override
  public void start(Stage primaryStage) {
    final AnchorPane root = new AnchorPane();
    final TabPane tabs = new TabPane();
    final Button addButton = new Button("+");

    AnchorPane.setTopAnchor(tabs, 5.0);
    AnchorPane.setLeftAnchor(tabs, 5.0);
    AnchorPane.setRightAnchor(tabs, 5.0);
    AnchorPane.setTopAnchor(addButton, 10.0);
    AnchorPane.setLeftAnchor(addButton, 10.0);

    addButton.setOnAction(new EventHandler() {
      @Override
      public void handle(ActionEvent event) {
        final Tab tab = new Tab("Tab " + (tabs.getTabs().size() + 1));
        tabs.getTabs().add(tab);
        tabs.getSelectionModel().select(tab);
      }
    });

    root.getChildren().addAll(tabs, addButton);

    final Scene scene = new Scene(root, 600, 400);
    scene.getStylesheets().add("tabs.css");
    primaryStage.setScene(scene);
    primaryStage.show();

  }

  public static void main(String[] args) {
    launch(args);
  }
}

with the css (tabs.css) file:

@CHARSET "US-ASCII";

.tab-header-area {
  -fx-padding: 0 0 0 50 ;
}

I don't want the new tab with apps opening when I open Firefox, how to fix this?

I want to just the home page to open without the new tab with a search bar on this issue.

Sometimes the home page changes are caused by a new extension or external software change your Firefox settings. These can sneak in when you install other software, as many free programs include a set of less useful things.

Could check you your extensions for the actions essential or unrecognized? Open the page modules using either:
- CTRL + SHIFT + a
- "3-bar" menu button (or tools) > Add-ons
In the left column, click Extensions. Then, when in doubt, turn off. Or if it's obviously nonsense, delete.

If the button Delete is absent for an extension, you can usually find a way to remove it using the Control Panel, uninstall a program (or all what is it called now to the point Windows 8.1). By clicking on the column heading to sort by date, "installed on" is useful to find and remove unknown elements not trustworthy bundle or other additions.

Once your system is clean, your preferred homepage appears, either immediately or after the update the setting in Options?

Every time Firefox opens, I get new tab, with my desired as a tab page I click on get to. How to get back to how it was in previous versions?

After updating to the latest version of Firefox, when it opens I get two tabs, and one that appears on my screen is new tab with my homepage on the other, which requires that I click on it to go. Also, when I click on a link, the same thing happens, a new tab page comes up, with what I clicked on as another tab I have to click to get to. It's actually quite boring and inconvenient. How to get back to the way it was, so that when I run Firefox it opens on my homepage, and when a new page opens, I see the content of the link I clicked on? This new and improved IMO is really new and worse.

A further extension could have snuck in. These can be bundled with other software you may have installed recently.

Try turning off all non-essential or unrecognized extensions on page modules. Either:
- CTRL + SHIFT + a
- Firefox orange (or the Tools menu) button > Add ons
In the left column, click Extensions. Then, when in doubt, turn off. (Or so completely junk, delete).

Typically, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.

That get rid of the extra tab?

Note: I also suggest to visit the Control Panel, uninstall a program and by clicking on the column heading "installed on". This should bring the most recent additions at the top and group by install date so that you can examine the software may have unexpected how have been installed.

Uninstall the toolbar Ask and it should work again. There is a compatibility issue with the Ask and Firefox toolbar that prevents the opening of new tabs.

- Also check your list of extensions, you may be able to uninstall it from there - https://support.mozilla.com/kb/Uninstalling+add-ons

When I open Firefox, my home pages (4) shall, after a slight delay, a new tab appears with links to social media and the new tab is active. I want to stop the new tab to open!

Uh-oh, you may have installed a non official package containing the update. If your download history indicates the source, can report you here?

Your "more system details' shows the extension MySearchDial. I recommend you to remove that from the addons page (if possible) or from the control panel.

Either:
- CTRL + SHIFT + a
- Firefox orange (or the Tools menu) button > Add ons
In the left column, click Extensions. Then find MySearchDial and remove (or at least turn it off).

If necessary, open the Control Panel, uninstall a program, then click on "installed on" heading of the column to bring recent infections, uh, additions, upward.

The last version doesnot open new tab with google even after editing about: config

Until two days ago, that the new tab opened with Google.com. After the introduction of tiles in a new tab where the tiles with suggested sites are displayed, even after editing with subject: config, there is no change. Set in a new tab button suggested only the sites or blank page that crushes everything: config it seems

Firefox has tiles on the new tab from Firefox 13 page. But something has just changed: 41 Firefox no longer use the browser.newtab.url parameter in topic: config because he was constantly attacked by malware. From 41 of Firefox, you need an add-on to change the new tab page.

Here are a few options (I'm learning more all the time):
- If you are already using the "Restorer of classic theme" or "Tab Mix Plus" extension: There is an option somewhere (!) in his dialogues of the parameters to select another page in the new tab.
- If you want to use your new tab homepage: Try https://addons.mozilla.org/firefox/addon/new-tab-homepage/
- If you want to set another page or a completely blank page: Try https://addons.mozilla.org/firefox/addon/new-tab-override/
- If you want the cursor to move in a search box in the page: Try https://addons.mozilla.org/firefox/addon/custom-new-tab/
Use only one of these methods at the same time, otherwise there may be conflicts and dysfunctions.

Setting up substitute new tab and new tab custom

After installing one of these extensions, you must use the Options page to set the new desired tab page (instead of use subject: config).

Open the page modules using either:
- CTRL + SHIFT + a (Mac: Cmd + shift + a)
- "3-bar" menu button (or tools) > Add-ons
In the left column, click Extensions. Then on the side right, find the new tab replace or custom new tab and click on the Options button. (See first screenshot attached).

New tab Override

Depending on the size of your screen, you may need to scroll down to enter the address in the form. (See second screenshot attached). For example:
- (Default) page thumbnails = > subject: newtab
- Blank tab = > subject: empty
- Built-in Firefox homepage = > topic: welcome
- Any other page = > full URL of the page
Then tab or click this form field and you can test using Ctrl + t.

Custom new tab

It is easy to enter your favourite homepage address. If you check either of the boxes, the expansion will set the focus in the page as well, for example, the cursor will be in the Google search box. (See third screenshot attached). I had to leave Firefox and start it up again before new custom tab started working, but this may have been due to tests so many extensions back to back.

Success?

Why can't I just open a new tab with the "Plus" sign or "command-T"?

This problem is Firefox on your Mac?

In the left column, click Extensions. Then, when in doubt, turn off.

Often, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.

What helps with the button "+"? If so, you can name the specific extension that caused the problem?

You can also see the Plugins page modules. You can never use 'activate' to disable plugins that you do not usually use.

There is not an integrated framework for the opening of new tabs "unrelated" everywhere except at the end of the tab bar.
