This is one of THE BEST addon someone could ever need.
If you have more than one identity or email account you use in some site, you MUST install this addon.
You can have multiple tabs of the same site, using a different identity (account or email) in each tab.
All I can say is I DO RECOMMEND THIS ADDON...

Esta eh uma das melhores extensoes que alguem pode usar. Se voce tem mais de uma identidade ou conta de email que usa em varios sites DEVE instalar este addon.
Voce pode ter varias abas do mesmo site, com uma identidade (login ou email) diferente em cada uma delas.
Recomendo muito...

Would be nice to be able to sort the containers or re-arrange them, also sync.

Prise en main rapide, intuitif, efficace, interface claire sans fioritures.

I really wish container settings would sync across multiple PC's.
I wish this add-on was available for android (and synced).
Other than those two things great app.

I just temporary disable and all setting is gone 😤

Only more icons are needed to distinguish my containers. Or atleast giving the option "to hide the icons"/"choose a blank icon" since I'm using emojis in the name of the containers.

Thank you for your work!

Awesome and useful add-on. More icons would make me give this 6 stars!

Amazing, this is a life saver for me.
PLEASE add the ability to sync containers settings with firefox sync

Leaky. I've got three containerised tabs open to crosscountrytrains.co.uk showing different legs of a journey. Trying to book through one tab gives a booking connection to a different tab.

Awesome plugin to keep apps seperated

Flawless! I can separate the big data collectors to a large extent :)
Even stronger functionality against Google and Amazon similar to the Facebook container would be nice.

Serious usability issues. It does not reliably open the website in the proper container, even when you check "Always open in Personal" option. The reason is because there is no way to manually specify which URLs go with which container. Instead, you have to check the box after the page fully loads to tell it to always open in the current container. You cannot always tell the current page to open in a *different* container. You cannot manually write a whitelist of which URLs go to which container.

The reason this is problematic, is because oftentimes, you will get redirected from one page to another after logging in. You'll open your Social Media tab, go to the site, log in, then check "Always open in Social Media". But then the next time you navigate to the site via URL or bookmark, it will open in the standard container because the rule was made for the signed-in redirected URL, not the original URL. You can't open the original URL in the Social Media container because you get redirected immediately to the redirected URL. And you can't open the original URL in the standard container and request to "Always open in Social Media". So, you have to open your Social Media container, log out, make sure the log-in page is set to "Always open in Social Media", then log back in. What a pain!
