Excellent for splitting up my various browsing personae. If this could also work on the path within the domain, it would be even more useful.

While it lacks some features, the base is pretty good and I use it every day.

This addon completly change my work life.

Very usefull. But whenever I open Firefox, all of my saved pages/tabs can't automatically place into container.

Very useful, i use it a lot to login to multiple aws accounts

Very useful.

A killer feature. Converted regular Chrome users to Firefox because of this.

Love this add-on. I use it all day every day. Thanks to the team for creating this. I no longer use different browsers to contain my different accounts & sessions.

Feature Asks / Ideas
* Is it possible to create a key command for opening new container tabs? Maybe 1 Key commend command + shift + T which opens a window to select a container by number (1-personal, 2-work, etc). Note, this is a solution while the actual user need/job to address is making it easy and quick to open the container that I want without having to click into a window to select it. Opening tabs is such a frequent action that reducing even 1 click would rule.

* Is it possible to map a single website to multiple containers? For example, gmail can be mapped to personal and work. Instead of locking it to just personal. That way, I open the right container, and then just type in gmail.com and go, no need to double check with me. The user opening a specific container means they know which session they want to run.

Thanks so much Moz Team!!! :)

This is absolutely fantastic add-on. It was the driving reason I started using Firefox again and I'm very pleased with it. I used to have to use multiple browsers with private modes to stay logged into the same websites under different accounts for work (Mostly AWS accounts). Now they are just different tabs. THANK YOU Mozilla!!!!!

Almost perfect! Allows you to set certain sites to always open in a specified container, which is perfect for separating personal tabs from work-related tabs. If this could also work for paths as well (and not just on the domain/subdomain level) that'd be fantastic! Being able to use my work profile for github.com/[workspace] and figma.com/[workspace], for example, would absolutely rock my world.

UPDATE:
I really need the containers to be grouped (for easier access and management), manually sorted and bookmarked with container information attached to be easily restored.
I am developing a web site. I have test users with their roles on site. For each user I created an individual container. 6 roles require 6 pages to be restored every time I reload the browser. I want them be restored automatically in their respective container at the time when the Bookmark was created. One site, several bookmarks with individual containers for each test user/role.

ORIGINAL REVIEW 2 years ago
I used to open Chrome for one Google account and Firefox for another. To check business emails on Gmail and to view videos on YouTube, for example. It consumed quite a lot of resources on my old Dell Vostro 3700. Now, I can manage all my "personas" in Firefox alone, which I personally like more.

But, the new "problem" now is it's hard to find necessary tab on Windows task panel. So, I suggest, that not only individual tabs can be marked as containers, but every FireFox window could be assigned a default "persona" with different coloring and EVEN logo (I like the Fox, but sometimes it'd be useful to have those personalized icons to faster localize necessary tabs). PS. I use A LOT OF tabs (up to 50 in one session, I guess). So, saving time trying to locate a necessary tab would be cool.
On the whole, this is a really cool feature which is worth taking time to understand how to use. Firefox, please make a new button - Learn the Feature - so that it would be like an ed course with games, videos and tests (reading is boring and confusing, as you know).

"Limit to Designated Sites" checkbox keeps being unfilled automatically. This has happened multiple times, even right after I enable it and go back to the previous menu
