Modern browsers should really be treated like operating systems because they have so many capabilities and are so complex. I try to run all of mine in separate virtual machines on Debian Linux using virt-manager. Additionally, they're sandboxed with firejail (looking at moving to bubblewrap) and apparmor. I'm less concerned with my IP address and more with a website being able to access random files on my computer.
