I just wish that it wouldn't take FOREVER for websites to load.........

Very useful to have multiple sessions open, I did not have any problem so far with this addon.
I recomend!!

Very useful

Multi-Account Containers must be one of the most useful Addons arround. Recently though it is not possible to open a site in another container if it has been assigned a default container.

One of the best addons.

I would have put 5 stars if there was as much customization as in Temporary Containers, but I hope that will come soon.

Very easy to use and user-friendly.

It works really great, I am leaving the last star so I can rate it better as it keeps improving, it might add some kind of group bookmarks, so let's say you are at work you just open all the work tabs at once (just an idea). As always Mozilla rocks!

If Firefox has one "killer feature" this is it. It completely transforms the way a browser works, essentially creating sandboxed groups of pages that can only see others in the container and nothing else. It makes using the same site with multiple credentials painless and overall increases the security and privacy of browsing exponentially. If I had one gripe it's that the UI is a little clunky and it could really use some love. Otherwise, a huge thanks to the team behind this. You should be marketing this way more than you do.

love this extension for keeping my privacy private across the internet. i had no idea until i discovered this extension that sites such as facebook tracked u all across the internet. thanx firefox! ure still #1!

This nearly replaces Firefox Profiles for me and is so much easier to manage. The automatic rules for always opening certain sites in a container is great and makes logging into multiple accounts for a service in one browser possible without Guest profile windows or private browsing mode.

This has been great for separating certain categories in a sandbox-like manner so that even if I leave cookies etc from say Facebook (created a container category for Facebook) and I go to my Banking site (in the category of Banking) there is no visibility between the two, so Facebook doesn't get to datamine anything about my banking (also a security precaution, security in layers like an onion), etc. Also this is super simple to use and allows me to organize my tabs more efficiently (I use a lot of tabs).

Amazing and helpful. Makes working with multiple Microsoft accounts for different things so much easier. Also works with Facebook Container extension. Makes everything a bit more private with how it contains cookies.
