Firefox vs Polypane: What are the differences?

1. Browser Compatibility: One key difference between Firefox and Polypane is that Firefox is a standalone web browser, while Polypane is a web development tool designed specifically for creating and testing websites across multiple viewports simultaneously.

2. Viewport Management: Polypane offers advanced features for managing multiple viewports, allowing developers to see how their websites respond to different screen sizes and devices. In contrast, Firefox focuses more on browsing functionality and lacks the comprehensive viewport management tools of Polypane.

3. Developer Tools: Polypane provides a wide range of developer tools tailored for web design and debugging, such as live CSS editing, element inspection, and performance analysis. While Firefox also offers developer tools, the depth and specificity of tools in Polypane are more extensive and catered towards web development workflows.

4. Collaboration Features: Polypane offers collaboration features that enable developers to easily share their work with team members, clients, and stakeholders. Firefox, being primarily a browser, does not have specialized features for seamless collaboration and project sharing within the tool itself.

5. CSS Grid Debugging: Polypane includes in-built tools for visualizing CSS Grid layouts, making it easier for developers to identify and troubleshoot layout issues. In Firefox, developers may need to rely on third-party tools or browser extensions for similar CSS Grid debugging functionalities.

6. Accessibility Testing: Polypane integrates accessibility testing tools to help developers identify and improve accessibility issues on their websites. While Firefox does have some accessibility features, Polypane offers more comprehensive tools for thorough accessibility testing.

In Summary, Firefox primarily serves as a standalone web browser, while Polypane focuses on providing web developers with advanced tools for designing, testing, and collaborating on multi-viewport websites.
