Eclipse Oxygen, JDK 1.8, Firefox 47.0.1 and Firebug Setup

The Classic Selenium Setup Stack

• Eclipse Oxygen: the IDE version commonly used for writing and running Java-based Selenium test scripts.
• JDK 1.8: the Java version required to compile and run the test code.
• Firefox 47.0.1: an older Firefox version historically used with the legacy FirefoxDriver before GeckoDriver became standard.
• Firebug: a browser add-on used to inspect page elements and locate their HTML attributes for building locators.

Why Version Matters

Older Selenium/Firefox setups needed specific matching versions to work correctly together; modern Selenium versions generally handle browser compatibility more automatically via updated drivers.
