Bringing back PWA ?

[gunir]

Firefox killed PWA for Firefox after version 84, I believe there's still old source code of this component, would be great to bring it back!

PWA is very useful in some cases:

• Isolate Floorp's cache, indexedDB to prevent slowness (if cache is too big or indexedDB is too big)
• Isolate huge web service from Floorp to optimize resource usage
• I know that PWAforFirefox exists, but it doesn't look very comfortable because it requires users to install PWA Launcher, which is uncomfortable
