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).

This is very useful add-on. Only one small thing is missing. I wish I could make one of my containers as my default container. So when I open a new tab from any other app (e.g. clicked on a URL from Skype), it would always open in my default container.
This small functionality will make this add-on complete.

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!

This is an absolutely brilliant extension, the setup is super simple, you can create as many custom containers as you like. Personally I've kept all facebook owned sites in the facebook container, I've then got one for all google owned sites, one for twitter and then general ones for the different types of sites I visit, so tech, news, general, personal, banking. Basically you create the containers, create a new tab in the container, go to a site and then tell the extension to always open that site in that container. Bingo, you're done. And, the longer you have it, the more sites you find yourself adding to each container. This coupled with Privacy Badger and HTTPS everywhere and I know less of my information is leaking out. I will say, it's sad that the online world has now got to a point with tracking that we have to do this sort of shit. But, if it forces the likes of Google, Facebook et. al. to change their ways then I'm happy to do it.
