Great app for working multiple accounts, for multiple clients is an amazing time saver.

Fantastic extension! My only wish would be to have keyboard shortcuts or mouse gestures I could map to open new tabs in specific containers.

Always open in DEFAULT container does not work. It always asks me since I one time opened site in non-default container. This behavior is annoying.

In a World where Privacy has become Luxury, or a hard Task to implement, this Add-on like Firefox Multi-Account Containers, like Linux and Privacytools.io and many others Libre and Open Source Software and Tools contribute to help People fighting against the monopolistic Plagues like Microsoft, Google, Facebook, Amazon, Apple etc

A great addon, but it's missing a few features:

- Container sync
- Ability to manually edit container assignments and use wildcards. E.g. it's useless for something like Salesforce where every sandbox and scratch org has its own domain.
- Ability to assign URLs, not just domains, to different containers.

Very nicely done. It allows to compartmentalize my online life: one tab for Google products, one for Facebook, one for Amazon, one for banking, and the default for the rest.
Idea for a feature: have a per-container type option specifying whether new links opened from that container should open in the same container type or the default container (or even, specify in which container to open links).

It's a must have add-on. But it causes some serious problems with the copy-paste function throughout the system. As soon as I install this add-on and start using it my copy-paste function starts malfunctioning. I have to press Ctrl+C like 5 times to make sure that it would have worked at least once. It's very annoying to copy something and when you go to other place and press Ctrl+V, it turns out nothing was copied.
Now a days, it has starting causing problem with Whatsapp web as well. When I copy an image from clipboard directly into Whatsapp web, it shows a black image. But if I do the same using google chrome browser, where I don't have this add-on installed, it works fine. After months of headache, I have finally reached the conclusion that this add-on is the culprit.

very helpful tool when managing multiple accounts in one browser

Doesn't work in browsing private mode. Firefox 72.0.1 (64 bit)
Please solve !

This is the single most used add-on I have. My job requires logging into multiple sites with different accounts, and Containers makes it such a breeze. Brilliant add-on!
