The Servo open-source browser layout engine has supported making use of the Firefox Devtools code for the provided web developer tools such as the HTML web page inspector and browser console. But that support had fallen into disrepair. Fortunately, thanks to a useful Outreachy project, the code has been updated and now working nicely with the newer Devtools code.
Thanks to a summer Outreachy project, the browser web developer tools code for examining / editing / debugging HTML/CSS/JS has been revived for Servo. The code had to be adapted to work with Devtools from newer versions of Firefox. Plus improvements made to the Devtools console support within Servo. The DOM inspector integration within Servo was also further enhanced.
Those wanting to learn more about the revised Firefox Devtools support within Servo can find more details on the Servo.org blog.
