Woohoo import attributes are riding the @firefox trains (https://bugzilla.mozilla.org/show_bug.cgi?id=1777526) and are "technically" in Fx Beta - https://bugzilla.mozilla.org/show_bug.cgi?id=1947719#c9
This is going to be so nice once it lands in the release version. #javascript
@schalkneethling @firefox it's still disabled by default behind `javascript.options.experimental.import_attributes`
@krosylight @firefox Yup, but it is at least riding the trains. I was a little worried there for a minute as Firefox (and technically Opera) that has not added support yet. I first thought it might be a standards position issue, but no - https://github.com/mozilla/standards-positions/issues/373
