It works as intended. No bugs found.

I would like to see an option in the add-on that allows a "quick toggle" for when people click the + symbol for opening contained tabs faster, rather than press and hold.

Perfect, but really needs firefox sync

This addon is great! It should be included into Firefox.
And as repeated by alot of people already: It would be so much better if the container settings were Synced between devices... Or at least give us a way to import/export them easily

But it's definitely the biggest reason for me to use firefox, after many years of Chrome

Indisposable. Feature that converted me from Chrome. I really wish there was a sync for which sites open in which containers by default though.

Having recently moved to Firefox from Chrome (since Google messed with the multi personality settings) I was overjoyed when I saw this plugin.

It seems to do exactly what it says on the tin .. the only downside I can find so far is that it doesn't seem to sync between machines, so all the preferences need to be manually copied from laptop to desktop / etc .. which is a bummer.

Would be 5 stars if only the profiles sync'd along with everything else through Firefox Sync

ME ENCANTA ES EL MEJOR DEL MUNDO,LE DOY 5 ESTRELLAS.

Containers has allowed me to completely give up Chrome. I like the functionality, and it is intuitive enough that I will keep using it. Please install to keep Firefox going!

Very good

The best! thank you

great idea, but it breaks ctrl-shift-t functionality a lot of the time. also would be nice to select active add-ons per container.

Really good, does the job pretty well, cannot see myself without this extension ever again.

I would really like if theycould add the ability to add websites to a container directly via the extension icon.

It's really great, but I wish the settings I have for each container were ported over with Firefox sync. The containers, settings for each container, etc. I understand this request may have difficulties I don't understand, but this problem is the only thing stopping me from rating this add on as perfect.

Great to split my work identity from personal identity. Great to simultaneously use the same site using two accounts.

Awesome for Multi-Account Task!

A recent update seems to have caused CPU usage to go out of control with this extension enabled. I've disabled the extension, and noticed I still have Container tabs functionality, albeit without the extension toolbar button - so I question the need for this extension.

Container tabs have quickly become a must-have feature for me. I have quite a few sites where I actively use multiple accounts (Google, Microsoft, Amazon) and not having to use a separate browser with a completely separate profile and set of addons is great. Even with sites that do allow simultaneous sign-in with different accounts, opening, for example, a work-related link in my work container ensures that it will use my work Google and Microsoft accounts and not accidentally leak/link any personal data.

Does the job very well. Imo it should open the contextual menu allowing to select the kind of container on a right click instead of the long left click.

Nice
