Well, feel free to remove the line if that does not suit your usecase. It's a template, you should adjust it to your needs.

We feel that opening the window is a nice helper for most scenarios, so I don't see a reason to remove this.

While I agree with @LinusBorg that we everyone is able to make the template fit to their needs, I think this is a bit more complicated than that. For instance, those of us with a Chromebook that run their dev environment in a chroot (with Crouton) will experience the same error as Chrome is not detected from within the chroot. While there are options to open Chrome anyway, I totally understand that Vue will not implement such platform-specific workarounds.

I do however think it's important that if there is no browser detected, the error will be ignored.

That behaviour is customizable since Nov 12, 2017 in /config/index.js
