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)

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!! :)

mandatory feature, which is working in firefox. thanks guys

Really a life saver feature from Firefox. Now I can use multiple accounts from one service provider without logging out. Really good.

I hope the extension can save the settings when it is deactivated. The current situation is that when the extension is deactivated by mistake and then activated, the new category settings in the container tab and the pinned tabs in the container tab will disappear, and the URL of the pinned tabs in the container will be lost without bookmarking.
