I used to always include `--no-remote` here but it seems `firefox -P <profile>` now works, too, even when another Firefox instance is already running. Is anyone experiencing the same?

When I last tested, it varied by platform.

Linux was happy to open a new instance without the `--new-instance` option (which is implied by `--no-remote`), but macOS required it.
