Is babelrc being ignored?

Choose one: is this a 🐛 bug report or 🙋 feature request?

This is possibly a bug.

🎛 Configuration (.babelrc, package.json, cli command)

.babelrc

{
  "presets": ["env"]
}

.browserslistrc

last 1 Firefox versions

🤔 Expected Behavior

regeneratorRuntime shouldn’t be used since I’m targeting only the most recent Firefox version, which natively supports async/await.

😯 Current Behavior

ReferenceError: regeneratorRuntime is not defined

🔦 Context

Using babel-polyfill works, but since I’m creating a Firefox extension targeting the most recent version of Firefox, I don’t want to transform async/await.

I encountered a similar problem. It looks like that Parcel (or Babel?) ignores .browserslistrc It should work when you add the query directly into .babelrc

{
    "presets": [
      [ "env", {
        "targets": {
          "browsers": "last 1 Firefox versions"
        }
      }]
    ]
  }

But why do you use Babel at all when you target a modern browser?

[jgrassini]

To disable Babel you remove the .babelrc file

Do you use the --no-cache option when you build the project? parcel build --no-cache ....

With the cache Parcel does not pick up configuration changes when the code did not change.
