Great. Now I have the control of all my accounts.

Not the best... It takes too long to open every time the proper container before open a web page. I wish I could link up every single url to the specific container and make bookmarks of it. So this extension is just half-productive.

I'm stunned that this feature isn't standard in all browsers. If you have multiple Gmail and social media accounts, it's a life saver!

This is an instant ESSENTIAL tool for modern web browsing to reduce cross-site tracking. I sure feel a heck of a lot better having the most obvious tracking sites (Facebook, Google, Microsoft, Amazon) isolated from each other.

Great feature. Previously missing sync, but now that's been added.

This extension should be built into Firefox to complement the browsing experience (because there are not tab groups)

Arguably the "killer app" of Firefox. I cannot live without this feature. It's great for having multiple accounts for the same page open at once and for compartmentalizing/separating sites from each other even further

Game changer!

Me ayuda a organizar mejor mis pestañas y cuentas.

Very helpful.

Is there any way to synk container tabs across my 2 PC's since im logged into the same Firefox account? As in have exactly whats open on PC 1 synk/open up on PC 2? Logged in and all?

It's a very useful add-on to privacy. Thank you very much for the development team.

I really like this feature; and a big reason I'm using Firefox as my default browser now.
Although one thing that I've noticed is that [in every device that I use Firefox browser on] I have to create all the containers over again--This is with signing in to Firefox browser and syncing... (Maybe it's a Bug that needs squishing...)
I'd definitely recommend this add-on feature to anyone who is concerned about their online privacy and to help avoid all of those malicious trackers and browser finger-printers that are seemingly everywhere on the internet these days. 5/5
Thank-you Firefox Team!! :)
