Great addon. I use separate containers for social networks and google, for job and for personal usage. Facebook/google trackers are on almost every page, and I don't want my web surfing to be tracked and recorded.

работает

This is an amazing feature, keeps my business separate from my day to day activities from banking from social media etc.
A separate container for every social media network and account. If I can't stop them I'll make sure to give them hell xD

Very usefull.

One of the best ideas for browsers! Would be great if tabs automatically opened specific tab containers for specific domains

Excellent

This is so useful if you don't want certain sites to communicate with each other in your browser. Would be nice if they made it easier to switch containers without needing another addon for that.

Great for Privacy tho

In my search to replace chrome I had the hardest time finding a replacement for having multiple profiles. This add on works under a different paradigm than the profiles in Chrome, however, once I got used to the way it worked I'm finding it to be a proficient replacement for that feature. A few tweaks or additional settings would be nice but otherwise containers are fantastic.

Truly a must have! I use it in combination with "Simple Tab Groups" and couldn't be happier.

This is a great feature for developers. I work on different projects with different Jira, code repos, etc. and this makes it so I don't have to login and out constantly. Saves a ton of time/annoyance. The only addition I'd like to see is syncing since you have to set it up for each new computer.

Amazing idea, flawless execution. Kudos to mozilla team. Keep up the good stuff.

Very good. Lets me keep things together. And apart.

This plugin is great. I have removed my "facebook" sessions plugin and I use Tab Session Manager sessions for Facebook and Google now. Which means I can log-in to different Facebook and different Google accounts at the same time.

I keep another for private email and browsing. Another for work matters. Get the picture? It is like being able to have 4 or 5 computers running Firefox or 4 or 5 firefoxes on the go at the same time. And I believe in this time, this is a NECESSARY plug-in.

Pity is this is not on Mobile. A great hole in the usefulness is that containers themselves do not get synchronised. Is there a Sync. API for that plugins like this one can use?!

One 'extra' I'd like is for the "Always Open in ___" feature to accept sub-domains or a URL pattern. I'm putting that in here because I can't use Multi-Account containers with Google/Gmail when "[x] tick that box". With that off, Multi-Account keeps Google tabs separated. Just an idea.

This is a time saver as i use different accounts in Mozilla for my parents and for myself.
Love it. Recommend it.

Amazing idea! Let's hope it really works.

Amazing tool! I manage several different Office 365 tenants and this allows me to setup admin and test user profiles for each without having to open private tabs or use multiple browsers.

Excelent!

Excellente extension pour gérer un même site ouvert avec plusieurs comptes en même temps. Super intuitif, pratique et fonctionnel, bravo !
