Selenium为Firefox提供原生支持。根据文件，
Controls the Firefox browser using a Firefox plugin. The Firefox Profile that is used is stripped down from what is installed on the machine to only include the Selenium WebDriver.xpi (plugin).

Chrome驱动程序：
WebDriver works with Chrome through the chromedriver binary (found on the chromium project’s download page).

The Chrome browser itself is discovered by chromedriver in the default installation path.
IE仅适用于Windows，
This driver is controlled by a .dll and is thus only available on Windows OS. Each Selenium release has its core functionality tested against versions 6, 7 and 8 on XP, and 9 on Windows7.
