The new FMN doesn't work in Seamonkey.

[Rombobeorn]

Aurelien Bompard asked me to open a ticket for this problem.

When I load https://notifications.fedoraproject.org/ in Seamonkey I see only a blank page. Apparently the Javascript program requires something that my browser doesn't have, so nothing is displayed.

This error message might be relevant:

Error: SyntaxError: expected expression, got keyword 'import'
File: https://notifications.fedoraproject.org/assets/index-82e1ce33.js
Line: 19, column: 17689
Code: login/fedora",name:"auth-login-fedora",component:()=>Jr(()=>import("./LoginFedora-631fa1c1.js"),[])}),t.isReady().then((

The new FMN is far from alone. These demanding Javascript programs are
becoming ever more common, and I can no longer avoid all of them. None
the less it's frustrating each time I have to start another browser and
cope with a worse user interface to run one of those programs.

For the record, I think we could make the resulting JS compatible with Seamonkey using this module: https://www.npmjs.com/package/es-module-shims
