BuiltWith For Firefox (Web Extension)
⏰ Old Post
This post is over 6 years old - it might be slightly outdated and consigned to the history books.
We've updated our Firefox add-on to be Web Extension compatible. This is a worthwhile upgrade if you're using the old Firefox extension as it now works almost identically to the Chrome extension.
