Separately from the issue of titlebars, I want Chrome's PWAs to open external links in my default browser (Firefox), not a new Chrome window.
Sadly I can't make Firefox install web apps as system icons because they removed experimental Firefox SSB support (they said to reduce maintenance overhead). Interestingly I found https://addons.mozilla.org/en-US/firefox/addon/pwas-for-fire... but have not tried it yet.
Yeah I hope Firefox could support desktop PWAs. I am moving towards Firefox from Edge due to the Manifest v3, but I cannot leave Edge due to its better PWA support, which my daily driver code-server relies on.
