A must-have for developers. Incredibly useful for multi-user testing.

very convenient to use. Allows me to open several accounts in a browser

This extension is great, a life saver.. I really need to open several tabs with different account set on it, before i was forced to use multiple private tabs/windows and it is frustrating, or using additional browser just for the needs. And then i came across this and try it. And it is very satisfying. no more multiple windows opened and save my time.

A life saver, I think this plugin should be built into the browser; As it's one of the main selling points. It helps with accessing websites that are bloated with trackers like twitter, without sharing it's cache with other sites.

Great and useful addon!

Works (almost) like a dream! With a bit of effort, setting up rules to split which websites fall into what container, splitting work and personal life is so easy! I have tried various solutions including multi-profile in both firefox and chrome family of browsers; it is very tricky when links are opened from other apps etc.

I would have given it a five star if containers worked well with addons that require login via their sister website. An example is the The Camelizer addon that has login via https://camelcamelcamel.com/. There is no way I can make it work with my personal profile.

one of my favorite add-ons for Firefox.

LOVE this add-on. So helpful. Especially appreciate that you can have different tabs in the same window to switch back and forth easily while still keeping your info separate!

Pretty good and useful. Only complaint I have is there needs to be more color options (not just 8) for the Containers.
