WebStorm 2020.3 Help

Web Browsers

On this page, you can configure the following:

  • Integrate installations of Web browsers with WebStorm, activate or deactivate launching Web browsers from WebStorm.

  • Specify whether a browser will be launched by running its executable file or through the default system command.

  • Appoint the default WebStorm browser in which WebStorm will open HTML files upon request by default, that is, when no browser is specified explicitly


In this section, specify which browsers will be available for previewing HTML output. The section shows the browsers from the predefined list and the previously configured custom browser installations, if any.

WebStorm is shipped with a predefined list of most popular browsers that you may install and launch automatically from the IDE during running, debugging, or previewing the output of an HTML file. WebStorm presumes that you install browsers according to a standard procedure and assigns each installation an alias which stands for the default path to the browser's executable file or macOS application.

If in your actual browser installation the path to the executable file is different, you need to specify it explicitly in the Path field.

In addition to the predefined browsers, you can configure as many custom browser installations as you need using the controls on the toolbar.


Select this checkbox to enable the use of the respective browser from WebStorm. The browser will be added to the context menu of the Open in Browser menu item and its icon will be displayed in the browser icons popup. See Configure the browser icons popup to learn how to hide and show the popup in the editor.

If this checkbox is cleared, the corresponding browser icon will not appear in the icons toolbar or popup.

NameIn this column, specify the browser name.
FamilyIn this column, specify the family to which the browser belongs.

In this column, specify the path to the executable. If the browser was installed according to a standard installation procedure, most likely the alias in the Path field points at the right location. If it does not, click the Browse button and select the actual path in the dialog that opens. In the dialog that opens, select the path to the executable file of the corresponding browser.

Default Browser

In this section, specify the default WebStorm browser that will be used by default for rendering external resources and previewing files with Web contents. This browser will be referred to as Default in the context menu when you choose View | Open in Browser from the main menu or Open in Browser from the context menuu of a file.

Default browser

Select the default browser from the list. The possible options are:

  • System default: Select this option to accept your operating system default Web browser as default for WebStorm.

  • First listed: Select this option to have WebStorm launch the first browser in the list. Change the order or browsers using the The Previous Occurrence button and The Next Occurrence button icons on the toolbar.

  • Custom path: Select this option to specify another Web browser as default for WebStorm. Type the path to the executable file of the browser or click the Browse button and select the path in the dialog that opens.

Configure the browser icons popup in the editor

In this area, configure whether you want WebStorm to show a popup with enabled browsers in HTML or XML files. This popup is used to preview the output of the current file in the browser.

By default, the browser icons popup appears only in HTML files. In XML files, the popup by default does not show up to help you read and edit your code without distraction. Use the For HTML files and For XML files checkboxes to have the popup displayed or hidden depending on the current file type.
