There are a couple of warnings that now appear in the console:

[0] {
[0]   message: "DefinePlugin\nConflicting values for 'process.env.NODE_ENV'",
[0]   details: `'"production"' !== '"development"'`,
[0]   stack: 'Error: DefinePlugin\n' +
[0]     "Conflicting values for 'process.env.NODE_ENV'\n" +

Likely caused by the webpack upgrade in https://github.com/mozilla/addons-frontend/issues/11419 but I don't think the underlying problem is new.

This is caused by: https://github.com/mozilla/addons-frontend/blob/5518fc1091241849f1f90634fe5d8f5d3cce2688/webpack-common.js#L132

Which has been there for a very long time, but I'm not sure why...
