Marionette vs Selenium: What are the differences?
<Write Introduction here>
1. **Execution Environment**: Marionette is tightly integrated with the Gecko engine, while Selenium is more versatile and can work with various browsers.
2. **Programming Languages**: Marionette is written in Rust, while Selenium supports multiple languages like Java, Python, C#, etc.
3. **Browser Automation Protocol**: Marionette uses the WebDriver protocol, while Selenium supports both WebDriver and HTTP protocols.
4. **Pages Loading Strategy**: Marionette waits for a page load event to complete before executing a command, whereas Selenium uses a dynamic wait strategy.
5. **Pop-up Handling**: Marionette has built-in mechanisms to handle pop-ups, while Selenium requires additional coding for pop-up handling.
6. **Cross-Browser Compatibility**: Selenium has better cross-browser compatibility compared to Marionette.
In Summary, the key differences between Marionette and Selenium lie in their execution environment, programming languages, browser automation protocol, pages loading strategy, pop-up handling, and cross-browser compatibility.
