This is one of the core plugins I use (in addition to Ublock Origin).

With the account sync, containers are also remembered across different computers as well, so I don't have to set up the containers on every new laptop or reinstall of firefox. Sometimes I mistakenly open a website in the wrong container because I don't always map every single website to a container, but most of the time it's a non-issue.

I'm surprised this is still an add-on and not a core Firefox feature.

Very usefull addon, perfect

It doesn't work for me. I cannot create a container where I am logged into Google and simultaneously a container where I'm not logged in.

L'add on correspond parfaitement à ce dont j'ai besoin

Very handy for managing multiple M365 or Google tenants.
For me, the only thing missing is the ability to have “private browsing” containers and a way to always open in a container, for example when editing a bookmark.

Recently it's been impossible to remove a site from the 'managed site list' - after a short period it re-appears. Perhaps its an integration issue with FF sync, or occurred when FF revamping the profiles management.

Excellent solution to manage multiple cloud tenant.

It's excellent. Very useful for using the same website with different accounts, like your personal and work accounts.

Quite handy once you get the hang of it. I love the ability to purge cookies across a container, very useful. Honestly feel like this should be installed by default and enabled via settings.

So, what do we have here? A mockery from Firefox. Let's go back to the proxy form - it expects "type://host:ip", but what do we actually get? No SOCKS5 support. I enter "SOCKS5://ip:port", and it complains about an unsupported record type. And the proxy has been verified as working. It simply wouldn't work with any functional proxy.

l💗ve the concept, the excution is not working so well for me at present - I am not sure where the issue is, whether its in relation to my password keeper or the sites I am accessing (particularly where there is MFA).

Some are just getting caught in a constant login error loop (personally, I think its the sites - Xero, you are the main culprit, and its not unique to this browser or function).

I am new to containers, so still working out how to use them but I desperately want it to work as Chrome profiles have been an ongoing resource vampire.
