Feature request: Make Cookie AutoDelete obsolete somehow

I've spent hours accross the recent years - and only found some awful temp solutions - to prevent Youtube and Gsearch to log me in but being still able to access gmail.
And for God's sake, it's working like a dream come true!!! With the addition of some scripts in Greasemonkey, I can safely and comfortably browse Youtube again! Thank You !

...Now I only need to find a module to hide the damned "Firefox VPN" invasive commercial spread everywhere in this addon...

A great and incredibly useful feature I use every single day. This is what true browser innovation looks like. Great work Mozilla!

This feature is so elementally useful, I am surprised that I have to add it as an extension. It seems like it should be a default feature. It is also one of the primary reasons I exclusively use Firefox. For a while I was happy to use Chrome exclusively because it provided what I needed and the synchronization or backup of each instance was very helpful. Since that doesn't cross web browsers, I only switched because Firefox, lately performs better and has this feature to increase my security, privacy, and account management ability. It doesn't take extra time to deal with these issues because I just have a few pinned tabs with the right container in them. It's awesome.

It's exactly what I wanted!
No more using multiple browsers to use multiple accounts or having your online info of an account being looked at by other.

I set it up little by little in the first week and then it's all on autopilot after that. The different colors for each tab keeps it well organized.

You can use this just to isolate 1 single account from the rest or you can use it strongly to keep each account on their colored container you created to have max privacy. I love this!

J'utilise cette extension depuis plus d'un an. Ma version Fox est 106.0 ma version Multi account container est 8.0.7.
Je rencontre depuis quelque temps cette erreur Google: 400. Il s'agit d'une erreur.
Le serveur ne peut pas traiter la requête, car son format est incorrect. Lors de la connexion (ex:https://calendar.google.com). Il suffit que je désactive l'extension pour que l’erreur de connexion disparaisse. Qql a t-il une idée j'ai déjà fait pas mal de test. Merci.
