I think we need all support we can get to fight Google on this, so I welcome Brave here actually.

I would recommend this extension: https://addons.mozilla.org/en-US/firefox/addon/pwas-for-firefox/
It adds support for PWA in Firefox. I use it because Firefox dropped native support for PWA in Firefox.
I used this for awhile but it’s more of a framework that requires vcredist and a local install of pwaforff binary to work around the short comings of mozilla pulling the plumbing out of the browser.
It’s a good workaround can have it’s issues when one part receives an update that the rest isn’t aware of.
