What major change was introduced in Selenium 3 compared to Selenium 2?

The addition of support for the W3C standard in Selenium 3 is a significant enhancement over Selenium 2. The W3C (World Wide Web Consortium) standard aims to unify how browsers and drivers communicate, which promotes greater consistency and compatibility across different browser implementations. By adopting this standard, Selenium 3 ensures that developers and testers can rely on a more standardized approach to automating web applications. This change is crucial for improving the reliability and effectiveness of tests across various environments. The other options do not accurately represent major changes in Selenium 3. While mobile testing support and headless browser features are important aspects of modern testing frameworks, those functionalities were primarily focused on improving the ecosystem surrounding Selenium rather than being direct upgrades in its core framework. Similarly, GeckoDriver is still necessary for Firefox browser automation within Selenium 3, as it adheres to the W3C WebDriver specification. Thus, the support for the W3C standard stands out as a key advancement in this version.
