Amazing plugin

Must have add-on for developers, power users, anyone who has multiple accounts on web sites / services, privacy conscious users and anyone who is aware of cookies and other more advanced tracking methods and want to keep activities separate (ex. Work, Personal, Development, Anonymous, etc.)

Very useful on Windows, but why is it not available on Android? Especially with Syncing that would make a lot of sense.

It's destructive now. E.g. after I added accounts.google.com to permanent container it stopped worked at all, I just can't login to anywhere. And no ways to remove it from permanent containers. So I have to remove this extension.

Really good extension for separation of concern :)

This extension was, originally, part of Firefox. I kind of understand the reasoning behind removing it and making it into an independent add-on (faster updating, independent development etc.), but I fear some day Firefox will drop it altogether, like it did with other technologies (let's not talk about WebSQL and the amazing beast that was XUL).

Anyway, this is an essential extension, full of features (don't forget to check its options for more essential features that come disabled by default, for whatever reason) and very light. There are lots of reasons for not leaving Firefox for other browsers, and this is surely one of them!

It was never a really good extension, but with the new update it bacame totally unusable. how can you make such a small plugin so complicated and unintuitive, quite impressive

Imagine that you admin lot of accounts. Containers made life easier.

As a non tech person, I appreciate the privacy options of Firefox and was excited to learn how to use the Container. I would give it five stars if there were better instructions on "how to". I haven't even been successful in using the help sections because of not knowing correct terminology. Obviously, I'm talking about very elementary steps, such as how to delete or rename a new container. Even more detail on how to actually put a web site into a new container would be great. ("See Spot run.") I ended up accidentally adding multiple new empty tabs to one of the containers. Here's the difficulty, I grew up with an IBM Selectric typewriter and never took a computer class in college. Lots of my friends are the same way. We just need more detailed steps. Maybe a "Tips for Baby Boomers" section throughout Firefox would be successful. Overall, I'm a huge Firefox (Moxilla) fan and even donate here and there. This is a great organization, and who else works so diligently for net neutrality? Donating to this organization is a privilege ... and a must.

The value of this extension is high but the execution is a bit niche. The value in function i think everybody can use, it should just be built in. :) Either way, it's here.

This is really cool feature. you can treat it as virtual browser. I am rating it 4 because I can't find easy way to list/find all other plugins supported with container mode. other wise it is really good stuff.

This is the key reason I will never stop using Firefox. Such an underrated feature.

Don't get me wrong - it's great, especially the recent update that allows you to manage your containers a bit more. BUt for some dumb reason, there's no way to add sites to the list without opening them first - so I have to add support.google.com, mail. google.com, and so on, instead of just typing in https://google.com or *.google.com. I can't for the life of me understand why this feature would be left out. I'll be keeping an eye on this, but I can't use the "Limit to Designated Sites" feature without it.
