The tool's support for preprocessors and CSS variable autocompletion enhances workflow efficiency, and future updates promise further improvements in CSS change tracking and Flexbox inspection. Overall, Firefox DevTools continues to evolve, offering comprehensive tools that benefit web developers by improving debugging and design processes.
