Solution

Just use the Live Server Extension. Install it from VS Code directly and you will be fine. You'll then have a link in the bottom of your editor to start and run the server automatically and also view your HTML immediately.

Apparently not if you're using the "Remote SSH" extension -- the default for many current developers. I want to set breakpoints in VSC, open a URL in the browser, and have execution pause IN VSC at the breakpoint. LiveServer doesn't do that, at least not without unmentioned configuration.

This helps a lot!, Thanks!

Note that as of today, it hasn't been updated in 2 years and has hundreds of issues in Github. I just removed it due to some Content Security Policy quirks, not sure if this is still good in 2021.

@MichaelJess: The Content Securtiy Policies have surely to do with your settings. The Application is still a great and helpful option for an integrated Live Server for Studio Code. https://marketplace.visualstudio.com/items?itemName=ritwickd‌​ey.LiveServer&ssr=fa‌​lse#review-details

@k.vincent It was a combination of the old live server and an equally old project template, even though I must say no idea how a plain HTML page would trigger this behavior. Anyhow, my recommendation stands in that it is best to look for well-maintained tools, and this isn't one of those. An up-to-date template with CLI dev server did it for me.

@MichaelJess Care to post an answer?

[Michael Jess]

@ZX9 You mean in addition to the comment above? I do not believe what I did is generally applicable. I am used to working with dev servers running from CLIs, and that is what is typically included in dev tools these days. In my case, the issue went away when I used Vue CLI as opposed to trying to host the Vue app via this VSCode plugin.

Live Server is great, but if you need HTTPS during your testing and development regime beware it's not always functional.

This is great. Reduced development time a lot. This auto refresh on file save. Can instantly see changes.
