Five stars if you save the containers and config for the site on firefox account and sync...

This is a really great extension that makes life much easier managing multiple clients.
What would be helpful in the future are adding key-bindings and synchronisation.
But again, great tool that I now use everyday. Thank you!

It needs sync to be able to be the same containers across all my Firefox installations on all platforms.

It doesn't sync. I would like to share the same container types between my computers. I have a Mac and a PC.

Great extension. What keeps me from giving 5 stars is that the keyboard shortcuts need to be mappable. It should be one command to open a container tab.

Very useful indeed! But I did notice a little problem. When I was in my Personal tab and span a child tab (also personal) to a Medium post as anonymous, one of my cpu cores goes up to 100% load.
That happen every time I spanned the Personal tab with this Medium post.
But, when I opened up the exactly same site on a regular tab (also as anonymous), the cpu was just fine.
So, I logged in at Medium in the Personal context, and the behavior was gone.
That happens on a Firefox Quantum in a Linux Fedora distribution.

This functionality is welcome. What was previously managed with multiple browser accounts can now be managed with only one (provided I use the same add-ons).
A few things that would make its initial and possibly regular use more convenient in my case, mainly different ways to sort websites into a container and make it defualt.
--ability to import bookmarks and bookmark folders so that they defualt to a specific container.
--ablity to sort "current tab" and "all open tabs" into a specific container when clicking on the add-on icon
--had minor issues with [are you sure you want to open this site in this container by defualt] message where it was sometimes unresponsive (I added an entire bookmark folder to a container and opened all at once) I mostly had to wait and reload before confirming.
--The ability to generally avoid/disable the [do you want this to defualt to this container] without individually using the [rmember for this site] setting might be welcome.
Consideration: if I'm already in a particular container and link to a site that would normally use a different container I would most likely not want it to instead remain in the current container or have me decide, unless in the defualt container. If the [remember for this site] option is not selected the message does serve that purpose but it's not useful when opening bookmarks. So implementation may have to be complicated or have to allow for various rules that are dependent on the current container.

Muito útil este add-on...

Seria perfeito se pudesse ser utilizado algumas ideias do add-on chamado "Temporary Containers", pois ele e meio difícil de entender .

Obrigado Moz & Dev's !!!

This is a great idea, as are containers generally: isolation much like virtual machines, but a level higher (above OS) so with much less overhead.

This particular app works well but is frustrating in one respect: you cannot specify to open a site in container X in future without already having done so. As it is, you must first re-open your site in a preferred container, then choose to always do so as a second (manual) step.

Even so, this app provides cross-site isolation. I feel much better having all my banking in a container no other apps see.

I accept Facebook tracking my tastes & movements as a fair exchange. If you don't, use the Facebook Container app but get this one anyway, for everything else.

Sometimes "Always open in {container}" doesn't respond. It seems like "Always open in Default" never works.

I would love to see some sort of way to save my preferences about which sites open in what custom containers, e.g. save it yo my firefox sync account, or save to a simple text file, or to some cloud storage or in whichever way that seems most applicable for this sort of data

The add-on idea is pretty great, but it does have a lot of bugs. An option to have shortcuts for each container would be nice, also when the Firefox browser refreshes itself, my containers are lost and I have to create them all over again which is pretty annoying. More icons for the containers would be welcome

Ich verwende das AddOn jeden Tag, da ich oft mit unterschiedlichen Accounts auf der gleichen Webseite angemeldet sein muss und nicht Lust habe, unterschiedliche Browser zu verwenden. Den 5. Stern bekommt das Tool, wenn man in Ordnern der Lesezeichen-Symbolleiste Favoriten gleich so abspeichern kann, damit Sie wissen, mit welchen Container es geöffnet werden soll.

This is much better than managing different profiles. This is more practical. Profiles have separate DB for stored passwords etc., which is annoying.

To make it easy to use, the Firefox team must work on easier short-cuts for container, container-tabs, default window for containers etc.

Finally, sync! 👏 Thank you very much!

I've been looking for container extension. First time user, so I'll be poking around first

Very handy extension, the only wish is that it would adjust your bookmarks with each profile
