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.
PyCharm 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. PyCharm 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 PyCharm. The browser will be added to the context menu of themenu item and its icon will be displayed in the browser icons popup.
If this checkbox is cleared, the corresponding browser icon will not appear in the icons toolbar or popup.
In this column, specify the browser name.
In 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 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.
Click this button to add a custom browser to the list.
Click this button to delete the selected customer browser from the list. Note that you cannot delete the browsers from the predefined list.
Click this button to specify a custom profile for Firefox or a browser of the Chrome family. The button is available only when Firefox and Chrome are selected.

Configure the browser icons popup in the editor
In this area, configure whether you want PyCharm to show a popup with enabled browsers in HTML or XML files. This popup is used to preview the output of the current file.
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.
In this area, specify the actions that trigger reloading HTML pages automatically in the browser or in the built-in preview. Learn more from Preview an HTML file in a browser.
