F-Droid

I mostly use Webapps (https://f-droid.org/en/packages/com.tobykurien.webapps/) for access to socials and have quick links to services where I don't want to login every time. Don't know if there's an alternative way to do this beside use apps like Insular or other App Isolation like, don't even know why browser don't do this by create profiles or container. I mean apps are just web container most of the time, and I know the reason why service provider want let you just use their app, but what's the browser excuse? What's your approach to this considering that Webapps application is outdated?
