Total Cookie Protection vs. Temporary Containers

[Hiche3]

With Firefox's native implementation of "Total Cookie Protection", that isolates 3rd party cookies, is there still a privacy benefit to using Temporary Containers?

There's no point in opening all sites in different containers, but you can still use this extension to isolate tabs from the same site from each other.

For example, if your Youtube watch history is turned on, you can open specific videos in temporary containers to prevent them from being added to your history and influencing your recommendations. You can also use this extension to open articles on sites that use local data to limit the number of pages you can read without being logged in.

Another possible use is to set the extension to delete your containerized history automatically (Advanced → Delete History), so that you don't have to open separate private windows.

for me the benefit is also that with canvasblocker and Faking - persistence+Store persistence data settings i can get a different fingerprint per temp container and keep the same fingerprint for permanent containers that i use for sites where i log in.

@io43 By "canvasblocker" did you mean installing this extension: https://addons.mozilla.org/firefox/addon/canvasblocker/ What did you mean by "Faking - persistence+Store persistence data settings"?
