version 2.6.1 can't debug angular-cli instances started from 'ng serv'

Visual Studio Code 1.41.1 (Windows 10 Enterprise x64)
Debugger for Firefox 2.6.1
Angular Cli 1.7

When trying to debug an angular application started via 'ng serv' and starting the 'Launch localhost' it throws:
**Unable to open 'main.bundle.js':Unable to read file (Error: File not found
(c:\Users\rcoleman\src\vs2019\P\Client\main.bundle.js)).**

Going to http://localhost:4200/main.bundle.js resolves correctly.

I believe this may be due to the fact that starting the angular application from **ng serve** serves the application from memory and _not_ from files on the disk.

The 'Debugger for Chrome' VS Code extension is able to properly function. What can I do to resolve this issue in the Firefox extension?

Thanks.

Reproduce the failure with VS Code 1.41.1, Angular CLI 1.7, `ng serve`, and the Firefox extension's `Launch localhost` configuration. Compare its handling of the in-memory `main.bundle.js` served at localhost:4200 with the working Chrome extension; done means Firefox debugging can open and map the Angular application without a missing-file error.
