Basically What the title says - Is Firefox "Total Cookie Protection" same as Sandboxing individual tabs, e.g. can I do two different logins to the same site in two tabs? Does it work the same way as Multi Account Containers? Thanks in advance!

Edit: updated the post title.

A sandbox is an application-level security feature meant to prevent exploits and data leakage. It’s about preventing your browser and OS from getting hacked.

The cookie thing is a restriction about cross-site tracking. Normally, cookies are restricted by being read by the domain that set them. However, this was abused by marketing tech, where they would embed code from Facebook or whatever on different sites, and then read them on any site that had that code. The Total Cookie Protection makes it so when a third party sets a cookie on a site, it can still only be read from the main domain of the page it was set on, preventing cross-site tracking.

Thanks ! I realized that the post title doesn't reflect what I actually wanted to ask (stupid of me) - so I will edit the question. But I still appreciate your write up. It is very helpful. Thanks again !

Oh, okay! Unfortunately I don't know about those features yet. I see Multi Account Containers is a plug-in by Mozilla, but I wasn't able to find anything about per-tab sandboxing.
