Improving Cross-Browser Testing, Part 2: New Automation Features in Firefox Nightly
It’s clear that WebDriver needs to grow to meet the capabilities of DevTools-based automation. However, that process will take time, and we want more developers to be able to run their automated tests in Firefox today. To that end, we have shipped an experimental implementation of parts of CDP in Firefox Nightly, specifically targeting the use cases of end-to-end testing using Google’s Puppeteer, and the CDP-based features of Selenium 4.

Earlier this year we decided to reduce the amount of unsolicited notification permission prompts people receive as they move around the web using the Firefox browser. This is an intrinsic part of Mozilla's commitment to putting people first when they are online.

Now we're making some changes to the workflow for how sites ask users for permission to send them notifications.

Why is CSS So Weird?
CSS is the design language of the web — one of three core web languages — but it also seems to be the most contentious and often perplexing. It's too easy and too hard, too fragile and too resilient.

WebHint in Firefox DevTools: Improve Compatibility, Accessibility and more
Creating experiences that look and work great across different browsers is one of the biggest challenges on the web. It can also be the most rewarding part, as it gets your app to as many users as possible. Testing legacy browsers late in the development process can break a feature that you spent hours on, even requiring rewrites to fix.
