Advice Request Do you log off from a website say MalwareTips after each session?

So the extension is obsolete

Without the extension, aren't the cookies still there until after I close the browser fully?

Example scenario using Chrome browser:
Watching Netflix and decide to check Gmail on another tab. I'm done with Gmail so I log out and close the tab. Then I decide to browse for some electronics on Amazon. Done with browsing and I log out from Amazon and close the tab. I continue watching Netflix.

Questions:
Wouldn't Google and Amazon cookies still be there until I close the browser fully?
Would my Amazon session be able to obtain data from cookies from Google and Netflix? In the same line of thought, Google would have had access to Netflix cookie, and Netflix would have access to Google's and Amazon's cookies.

At least that's my train of thought.

I do know there's Strict Isolation in Chromium based browsers but haven't read up on the feature fully.

Firefox has container functionality but I don't think there is a similar concept in Chrome/Chromium.

Yes but that doesn't make any difference. (Device-crossing) fingerprint is the current way for tracking instead of Cookies.

For that the Chromium Isolation exists. If you block Third-Party-Cookies they can't track you this way
Chromium' Isolation is browser wide while Firefox' extension is only per Tab which mean one compromised Tab is enough getting whole Browser session.

Site Isolation is a security feature in Chrome that offers additional protection against some types of security bugs. It makes it harder for untrustworthy websites to access or steal information from your accounts on other websites.

Websites typically cannot access each other's data inside the browser, thanks to code that enforces the Same Origin Policy. Occasionally, security bugs are found in this code and malicious websites may try to bypass these rules to attack other websites. The Chrome team aims to fix such bugs as quickly as possible.

Site Isolation offers a second line of defense to make such attacks less likely to succeed. It ensures that pages from different websites are always put into different processes, each running in a sandbox that limits what the process is allowed to do. It also makes it possible to block the process from receiving certain types of sensitive data from other sites. As a result, a malicious website will find it much more difficult to steal data from other sites, even if it can break some of the rules in its own process.

But cleaning caches still helps, like to get rid of etags.
