This is hands down one of the best browser features I've used! It helped me fully convert to using Firefox both for work and personal stuff.

Amazing I love this container. this is the reason I use firefox and not chrome.

It's OK and is enough to make me feel I can switch from Chrome's easy multi-profile support. But the containers add-on does not appear to sync settings via Firefox account, so that is a big pain. It also does not appear to let you select a default container for new tabs, which is frustrating. That later wish is actually the only setting I can imagine wanting to be able to set differently at home & work, so some care to be taken there. Keep working on it!

I find the implementation of Firefox containers extremely frustrating to use.

The Firefox containers require that I keep my current context in my mind when taking any action.

If I am on a container tab for for and I press "cmd-t" to get a new tab, I do not get another work container tab. Instead I get a non-container tab (or default container). Several times a day do I realize that I've been doing a specific kind of searching (google research) or general browsing in the wrong container.

This pollutes my container identity, history, and website preferences. My work search history is now full of non-work stuff. My search results are less relevant. My "goof around" container is now full of work results, and vise versa.

I prefer the Chrome model, where one whole window, and all it's tabs, are one "profile". This makes it much easier to use and think about.

This is an awesome, game-change extention! It's so great to make each website to have each own information! I'd like only to suggest the sync of the configuration between devices as it's a problem to have to configure which website to open with each container by default in each machine

This is such a game changer and much easier than working with accounts in chrome. Wish there was a way to sync settings with your firefox account though.

Cookie の保存先を使い分けて、隔離するアドオン。
追跡型 Cookie などが他サイトに読み込まれるのを避けられるので、追跡が多少されにくくなる。ブラウザやプロファイルを使い分けたりすると面倒くさいのに比べると、このアドオンのほうが楽。Cookie の保存自体を拒否するとウェブサイトの表示や利便性などに支障が出ることもあるが、このアドオンは Cookie 自体は保存するので支障が出ない。
とはいえ、Cookie 以外にも追跡手段はたくさんあるから（Remote Address とか、User Agent とか、画面のサイズなどなど）、「追跡を多少は阻止するかな」程度と思ったほうがよいだろう。

Very useful, i love it, thank you very much.

I love it, please consider making this available for Android as well.

Very useful, hope it becomes a standard addition to Firefox.

Antes me tocaba abrir ventanas incognitas u otro navegador para abrir cuentas de un mismo servicio sin cerrar sesión.

Teniendo en cuenta que Chrome permite tener múltiples cuenta y abrir sesiones mediante ventanas hacia que uno usuario de Firefox añorara algo así.

Con este plugin no tengo que pensar más en eso.

Funciona cómo indica y me facilita la vida un montón. Se acabaron los días de abrir otro navegador para abrir otra cuenta de una misma web :D
