I used to love this. But now it shows me a "You've opened 100 container tabs" popup every time I open it and insists that I write a review. Well, here's your review.

Great Extension but please disable the 100 tab popup

After opening 100 tabs through it it turns into annoying nag ware that keeps begging to ratings and sharing EVERY SINGLE TIME you try to use it. Oh, and it only wants you to share through fascist platforms Facebook and Twitter.

Screw you Firefox. And no, don't dare to hide behind 'oopsie, bug'. This infantile behaviour shouldn't have been in here in the first place. Not even once.

This extension right here is the smoking gun that convinced me to switch over to firefox, it's insanely useful and a great quality of life tool to manage multiple accounts and no other browser has this. I can now open (for example) YouTube with 2 different accounts or in a new container without an account. They can't track between each other, so it is of course a gigantic win for privacy too.

Insisted rating. One star deserved.

Excellent and unique feature of Firefox. Essential

Works great for me, easy to set up.

Honestly the best add-on in Firefox! It's the main reason why I use Firefox on PC. What makes it so unique and amazing is that I can for example have google search in a separate container without signing so I can search privately while having YouTube and Keep and other google sites signed in with my own account or any account I want, no other browser does this, all other browsers force every google site to be signed in with the same google account which makes it if you wanna use YouTube you have to be signed in to google search too which is terrible for privacy. And I can have any site I want open in a separate container which eliminates cross-site tracking completely, a more guaranteed way than using Enhanced Tracking Protection and uBlock Origin which are also fantastic and important to have enabled for privacy as well. This is an absolutely brilliant add-on. THANK YOU MOZILLA!!

There is currently a bug with the popup, where you have to click "Done" every time, which should be fixed soon (see issue 2813 on the mozilla/multi-account-containers GitHub repository).

This extension has always been helpful so I won't rank it down just for one mistake :)

An excellent choice if you want to have multiple online profile; it helps me a lot in my presentation and training.

Nags you to write a review EVERY TIME YOU OPEN A CONTAINER. Absolutely nuts.

Bullshit! Its such a great tool but after 100 panels you get a pop-up that can not be disabled!!!

"100 panels opened" prompt cannot be removed and will open even if you have clicked the share and review buttons

Great extension! The only issue I’ve encountered is with syncing — it seems to have a bug. I never choose “Always remember to open this site with,” yet it keeps automatically assigning websites. Once I disabled Sync, the issue disappeared. I wish there were an option to turn off this feature entirely. Aside from that, it works perfectly!

Fantastic!
