ice VS nativefier

There is also ICE.

Peppermint Ice (GitHub): Supports using Chrome, Chromium, Firefox, and Vivaldi as its browser.

Linux Mint has webapp-manager which works similarly to ice; and ice itself has a Github page, but I'm not sure how well they work outside of their respective distributions.

I don't know what you've already tried but for Kubuntu you could try the Peppermint OS Ice SSB There's a PPA

ICE is a good way of doing basically this, including creating the profile and giving it a “hide everything” userChrome.css, when you use Firefox: https://github.com/peppermintos/ice

Depending on which distribution you're running, you can try ICE - SSB Manager From what I remember it's available for the Debian based systems and I think Arch has it in the Aur.

"Should theoretically be installable/useable on any Ubuntu based distro (or any other Linux with some minor tweaking) .. ICE has been available on github for some time now:https://github.com/peppermintos/ice

If you're on Linux, check whether or not you can install https://github.com/peppermintos/ice

The Linux Mint Web App Manager is based on Peppermint OS ICE SSB Manager. There's a PPA

Oh by "Web Environment" you mean "my machine" lol!

I already got caught by this - a https://github.com/nativefier/nativefier app wrapping Youtube Music doesn't work, because Google detects somehow that you are not using a trusted browser and refuses to serve.

AFAIK there's only nativefier and peppermintos' ice.

Install Nativefier from Terminal using the command npm install -g nativefier

Something like nativefier perhaps?

It's still not quite the same as Chromium webapps, which are just isolated windows in the same core process -- FFPWA spins up entire other instances of Firefox -- and in effect operates more like Nativefier (with Firefox instead of Electron/Chromium)

is Electron considered a browser? cuz Nativefier is what i use
