WebDriver playback
The WebDriver playback feature in Selenium IDE lets you run tests in any one of the most popular web browsers: Chrome, Firefox, HtmlUnit, Internet Explorer, and Opera. By default, the WebDriver playback feature is turned off and is inactive. To run Selenium IDE scripts through WebDriver, turn on the WebDriver playback settings.
Launch the Selenium IDE and choose Selenium IDE Options from the Options menu. Switch to the WebDriver tab and select the Enable WebDriver checkbox. Now, restart the Selenium IDE to enable the WebDriver playback feature. However, on changing the browser name, restarting the IDE is not necessary.
