How can I choose the browser?
when I tried
browser = Watir::Browser.new :firefox
I get this error:
'
/usr/local/lib/ruby/gems/3.0.0/gems/selenium-webdriver-3.142.7/lib/selenium/webdriver/firefox/driver.rb:31:in new': wrong number of arguments (given 1, expected 0) (ArgumentError) from /usr/local/lib/ruby/gems/3.0.0/gems/selenium-webdriver-3.142.7/lib/selenium/webdriver/common/driver.rb:54:in for'
