### 🚀 Feature Request The event for `browsingContext.downloadWillBegin` is now [available in Firefox Nightly](https://bugzilla.mozilla.org/show_bug.cgi?id=1874365) as of today. For Chrome it's already present for a while. There are around 45 tests under page and library that are currently failing because of that event not being handled. Here the related BiDi spec: https://w3c.github.io/webdriver-bidi/#event-browsingContext-downloadWillBegin CC @hbenl ### Example _No response_ ### Motivation By handling this event it can be detected when the browser starts a new download of a file.
