good for getting around jerk moderators who block you cuz you don't give the same opinions they have sites like:city-data and other jerk run sites run by morons. Have to keep checking allow permissions to delete container data. Easy to make a mistake and send in non-container if you're not careful. Mozilla wants you to add their VPN to the containers but their VPN gets such poor reviews no need. slow to load up.

Cannot use the containers without giving a rating so you get one star. Nagging is a shitty tactic.
Edit: A review is not enough. Are you actually forcing people to post on facebook and twitter to gain access to this extension?

the review nag is annoying, but the feature is great and works well

works well, no problems so far, good isolation

Super useful extension. Enough for me to switch to Firefox.

I shouldn't have to rate, share, or otherwise promote an official Firefox extension just to be able to use it. Make sure this "feature" gets removed soon so I don't develop a competitor. 📎

Good functionality, but what's the deal with having to review...?

Why does this junk app keep asking me to review it?

This is very essential basic browser functionality which Mozilla have decided to lock behind a bunch of annoying nags and product promotions. Would be much better if it would just let me use the extension without wasting my time, and also if this functionality was integrated into Firefox.

Good extension, but UX is broken.

the "Open this site in your assigned Container?" page should really allow me to choose which container, rather than having "Current" and "last" container.
its just a bit awkward to use as a developer, when you need to spin up multiple containers quickly

nice addon, could be rated 5,but the nag take 1 off.

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.

Take off the popup at 100 tabs and it'll be 5 star again.
