After reading a couple of Firefox Multi-Account Containers instructions on on how to use, which I gave a positive Yes if it was helpful, I find I cannot get any website to open in a container. I've use nightly for 5 - 6 months?? I update Nightly almost daily. Gave Firefox testteam permission to install test automatically. Only thing I ever got was the original test version of containers. So installed the production version today. Do not find any right or left mouse button click to provide any accept to open a tab or a new tab in a container. Hold does not work. Spent last 45 minutes with no success. Moving on may attempt again or remove nightly, install production version with containers and see if that works.

Very handy!

Container tabs are wonderful. No more testing with multiple browsers, no more private browsing which share the same cookies! I really enjoy browsing freely on different websites, saving cookies but don't sharing them.

allows me to separate my cookies without worrying about contamination

It should be included by default in every browser. I only wish there was an option to synchronize my config across different computers.

Great idea, with a sleek user-friendly, intuitive execution. I found it easy to open, manage and use different containers. One missing feature that I've felt is the ability to process histories/cache's etc. within each container. e.g. "delete all history from container [shopping], but keep the other container data".
Otherwise, it's a useful add-on that helps users manage and understand their online footprint. Thanks for making it!

This is really great idea man!

Missing two main features: picking RGB colors and switching containers.

Good

Very useful for keeping my information safe. This removes the need of having different browsers open and helps maintain the cookies I use.

This add-on has much potential. Definitely 5* worthy if it had the ability to

1) store log in info in each container and
2) custom sort the container list (tab sort is of no use, at least to me).

Great to split personal and work or if you need to access same service from several distinct accounts like Google services. As Mettarefuge sayed, it would be nice to have more colors (good idea for the input).

Excellent for organization and privacy. Use it everyday

Great job. But can we have a more options for the colors? Maybe an input for RGB codes or a color picker. It would be nice :)

Works great and a it's great way to organize tabs. I would *love* if I could save a group of tabs in a container to bookmarks.

Good

This is a game changer. I loved Firefox in the past, but really had trouble coming back. The containers are amazing for many of us concerned about privacy, security, and organizing our online lives. These have made Firefox, once again, my go-to browser.

Definitely one of the indispensable extensions if you have multiple accounts on some sites like me. It works exactly as expected, fast and elegantly designed. If there’s one minor thing I still wish, it’d be showing in history which container each entry belonged to.

Great addon for those who need to access same service from several distinct accounts. (e.g. Google developer console)

My favorite part of Firefox!
