Hey, I’m tightening up my privacy like you. I’m not sure if containers are the best way to go, but Mullvad Browser is essentially what you are looking for. Its a firefox fork that has complete fingerprinting protection baked in. Its basically tor browser minus the tor network. Both it and tor have a button (“New Identity” feature) you can click to completely clean your session (cookies cache etc) without closing the browser.
You can also see what your fingerprinting profile by looks like using the EFF’s “Cover Your Tracks”. It also reports how unique your browser is, but don’t use this as a metric of how private and secure you are, since there are many other aspects you need to factor.






You mean 48 during the Nakba?
FYI 1967 was when Israel occupied the West Bank during the Naksa.
