* Work/personal separation

* Multiple AWS accounts

Also, I am very impressed with how well they're integrated into Firefox. For example, opening a link in a new tab will preserve the container. CMD+Shift+T will restore a recently closed tab and remember its original container. I really like the color coding too.

The only time I use private windows is when there is a glitch.

Sign-in to personal (while at work) to sync bookmarks if firewall allows. Depending on whether you trust your employer you could sync further personal settings.

Don't sign-in to work profile and no work bookmarks or settings/logins get shared.

Don't get me wrong: multi-account containers are a blessing for those rare days when you absolutely have to log-in to facebook.

privacy.userContext.enabled to true

privacy.userContext.ui.enabled to true

privacy.userContext.longPressBehavior to 2

I love using containers with privacy.firstparty.isolate set to true too for extra protection.

I never understand why Mozilla doesn't allow to enable this in the settings.

Of course you've always been able to setup multiple profiles for FF, but that is setup that I was usually too lazy for given it could be done ad-hoc in IE.

I have it configured such that middle-click opens links in new containers, and left-click opens in the current container.

Hide the popups with uBlock Origin. You pick the element with an inspector like tool and they are gone forever. Also use Cookie Autodelete to remove any information they attach to your browser.

If you really care about a site, make your choices in the cookie popup and grey/white list it in Cookie Autodelete.

I'm using a plugin called Cookie Autodelete for this and like it

Is the only different between this containers vs profile the container is tab base vs profile will be different windows?

The way my main FF browser is set up, I have multiple privacy enhancing extensions (including uMatrix), highly modified config, tightening of privacy preferences, WebRTC off, service workers disabled, telemetry disabled, etc and etc... This can create some problems on sites that pour hundreds of millions into tracking, data-collection.

So I have additional profiles that are Amazon-specific, Google-specific. If I facebook'd, I'd have a profile for them too. Each of these domain-based profiles are far more liberal (minimal extensions and such; fewer config tweaks). I even have a profile that's 100% Private Mode (ie, history, cookies... deleted after shutdown) with it's own set of config tweaks and extensions.

I use my privacy-enhanced default FF for most sites w/o issues. I wanted Google and Amazon completely separate while providing them more access to my browser (so that I could enjoy the full web experience without worry that a browser issue would make it easy for them to steal my entire browser usage). So they're free to rummage around, read cookies, access APIs - but they're only getting their own stuff back.

I feel profiles provide a better defense (all settings, cookies, storage in their own subDirectory) and much more flexibility than containers.

I don't bother with profiles any more, especially since there's a one click option to open all the container tabs in a new window as well.

The huge downside with them is they don't sync across devices. If/When this comes they will be perfect.
