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 :)

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

"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, 5-star add-on.. until you've opened 100 tabs. Then you need to click out of their review & share prompt each time you open.

I opened 100 tabs and it asks me to leave review and won't go away. Every time i click on it it greets me with 100 tabs again. Okay, here is your review, all usefulness of this extension is severely ruined by this constant annoyance.

Spamming to review and share? Interrupting user flow takes it from a great five-star tool to a one-star annoyance.

First of all, when clicking the multi-account firefox button, you are greeted with a "You've opened 100 container tabs" which doesn't go away. Then, to leave a review, the default behavior is to open the review site in no container. To log in using my personal google account i have to open the tab in the personal container. After a successful login, the tab does not redirect me to the previous review page. Pressing again the link to review says i am not signed in (default no container). Essentially containers are a half baked concept that breaks when using auth flows with identity providers and with no options to, open all links while in a container in the same container. This would have solved many issues.

Amazing must have tool has completely fix dealing with multiple accounts on services.

As others have noted though if the Rate this extension pop-up doesn't go away soon, the stars are going to start dropping.

great app 5-star. bs add that tells you youve opened 100+ containers needless and annoying. **even after rating this app it wont go away tf!

Excellent!

Wish they would disable the "You opened 100 tabs!" message that appears every time I use a container now...
