Alas, this is both a downside and an upside of Selenium.  It&#x27;s rather slow because it does need to spin up a Firefox instance, but it is very user-friendly and easy to learn because you can see exactly where you are at just by looking at the web browser.<p>You can run headless Selenium, and speed it up by using a static Firefox instance, but even then it&#x27;ll be maybe 2-3x slower than some of the others.<p>The only reason this is (in my opinion), better than other solutions is because you can see the physical webpage it&#x27;s loading, and for the sheer ease of use that this has.  You don&#x27;t even really need any coding experience to get a simple test running.
