How Can I Force JavaScript's `window.open()` to Open in a New Window Instead of a Tab?

Opening a New Window in JavaScript Instead of a Tab

When working with window.open() in JavaScript, you might encounter instances where Firefox opens the specified URL in a new tab by default, which may not be your intended behavior. This article explores how to resolve this issue and force the URL to open in a new window instead of a tab.

To accomplish this, you need to leverage the "features" parameter in the window.open() method. By specifying this parameter, you can control various attributes of the newly opened window, including its dimensions.

Here's the solution:

window.open(url, windowName, "height=200,width=200");

In this line of code, we are specifying the height and width of the window. When you provide these dimensions, Firefox will open the URL in a new window, separate from any existing tabs.

For further customization, you can explore the documentation provided at https://developer.mozilla.org/en-US/docs/Web/API/Window.open#Position_and_size_features, which lists all the available features and their usage.
