Is Chrome or Firefox better Selenium?
Chrome and Firefox are both well-known web browsers, but they have never been compared to each other in terms of usability. Actually, there are some differences between them that might influence the decision of which browser should be used for WebDriver automation.
For example, Chrome has a built in extension manager called Chrome Extensions. On the other hand, Firefox has a plugin called Firebug. Both of these tools can be used to set up WebDriver environments easily and quickly. The main difference is that Chrome extensions support user scripts while Firefox add-ons support user add-ons.
