This is one of many reasons Firefox will always win over Chromium-based browsers.

There's a few problems that continue to persist even after many years however:

1. Stop trying to shove Mozilla VPN down our throat.
2. Sync tells you to sign in despite already being so - just close the extension window and re-open when it gets to that point.
3. Once sync is enabled, it'll pull through all your containers, but it won't remove the default ones. Very annoying.

Cet add-on indispensable n'est plus maintenu depuis 1 an et est bugué. Par exemple, je dois sans arrêt retirer des sites de la liste des sites gérés par un conteneur car ils reviennent toujours. Ça rend l'identification problématique si un IDP (comme Facebook login ou Google login) se trouve réassocié sans arrêt à un conteneur.

This essential add-on is unmaintained for one year has some anoying bugs. For instance, I'm forced to remove the same website from a container managed website list again an again because it get reassociated again and again.
This cause IDP (like Facebook login or Google login) to fail everytime if their website is reassociated with a specific container. (SSO breaker)

One of the best extentions

Despite having the "Select a container for each new tab" box checked When you open a new tab, nothing happens. Not even contextual dialogue is activated. I have the extension installed and enabled, but I can't get it to work in Windows 10, not so in Linux Mint, which goes without problems.

I access isolated networks/labs via SSH SOCKS proxies. This plugin lets me access a particular lab simply by right-clicking on the new tab button and selecting the lab/network that I want to browse in. I wish there was an option or shortcut key (similar to Ctrl+T or Ctrl+Shift+T) to open a new tab in the same container as the current one, but this is still a huge win.

I've experimented with using it to isolate my personal browsing while on my work computer and while I don't know if my cookies are being separated, I'm pretty sure my browsing history is not. Oh well, it's still great for the first use case! :)

Because I'm used to the grouping feature of Chrome I wanted to give this one a try but this is anything but convenient to use. It's just cumbersome, too many navigations for renaming or adding groups and no toggle feature

Very nice, maybe some features:
- setting a container as default when opening new general tabs
- integrating history for every container
- make access to some containers pin protected

This addons is a must. And it would be better if each "New tab" is different for each container.

Really love this add-on.
But why is there no port to Brave (I don't use G-Chrome) or Vivaldi (yes, I use different browsers for different things, like some crypto wallets do not even have an option for Firefox, etc.), but Firefox is my main driver.
