Request blocking feature of Firefox DevTools is a super ergonomic tool for progressive enhancement 💛

If you're working with Python and need to download a specific Firefox or Thunderbird build, you can utilize mozdownload to simplify the process. I've just released version 1.28.0, which now includes support for Firefox on Android builds as well. github.com/mozilla/mozdow…

While implementing linking to IDrefs in the @Polypane Elements panel in v18, I noticed that the Firefox DevTools implementation lacked support for web components.

So I filed a bug report, Nicolas CHEVOBBE picked it up and Firefox 125 will include the fix!

🤩 Exciting! That's a significant update for test automation. #WebDriverBiDi is the standard, modern and speedy way to automate major browsers in the future (soon!).

The CSS `filter` UI in Firefox DevTools is *amazing*.

Now I don't need to guess at what units each of these require!

In Firefox 122, we changed the behavior of the Enter key in the Rules view to not move the focus to the next input anymore. This was frustrating a lot of developers so we reverted this change in 122.0.1 (released yesterday)
