Browser isolation

How can I easily isolate browsers? I want something for normal browsing that after every browsing session it deletes itself or deletes everything I did on it and I have different browser session on the same browser (I like brave so I want to have one session open for youtube, second for browsing, …)
I’ve looked at Kasm Workspaces but I didn’t manage to install it on Docker (on Fedora linux). I know I can use VMs to do it but I want something more lightweight like containers on docker.

Are you saying you want to isolate/sandbox your browser(s) from your entire system like a VM? If yes, then I recommend that you install your browser or browsers as Flatpak.

I think Fedora has Flatpak support by default on the GUI store.
