Extension and profile handling refactored
- fixed Chrome popup on local browser "--ignore-certificate-errors" (not shown anymore)
- introduced methods "get_browser_profile" and "add_extension_to_browser"
- reduced code duplicities + increased flexibility when dealing with browser profile (ChromeOptions or FirefoxProfile)
Added return value for CircleCI collect artifacts function
