I found a bug:
this extension thinks that about:addons page is container. I have disabled option to prompt to open new pages in container. So on all sites it opens pages in normal tabs and doesn't ask anything, if that site from where you opened new links - is not in any container. But there is a bug, that extension thinks that firefox internal pages are containers. So I would like not to be prompted to open page in container if I open "Reviews" link from my firefox extension description.

This is the only add-on that I was able to get the multi login working at all the time, so truly fantastic

I've been searching and searching and searching. This is the only one that works like the Chrome one. Doesn't kill your tab when you try to move it back or between other groups like the other leading solution. Thanks for your efforts.

It's nice and easy to use.
Just an inconvenient is when I tried to send mutiple tabs from my Android phone to Firefox Desktop, only one (sometime twos) that I can open correctly, others are just blankscreen.

Super!

This is probably the closest to Chrome's tab grouping. However I'm not really a fan of how logins and cookies are separate between containers. Still worth using anyways.

I've tried a number of extensions to find the ease of Chrome groups in Firefox and thus far this is the best one I've used.

I particularly like that each tab group functions as it's own instance for cookies. While it is somewhat tedious to set up services across multiple tab groups using a password manager in conjunction with this extension does speed up the process.

I would love to see tab groups sync across instances of Firefox as I have needed to set up the tab groups in each instance I use. Again, once set up, it works flawlessly and is intuitive on assigning newly opened links either to a specific group or otherwise.

Fir anyone else seeking a Chrome-like experience I would recommend giving this service a shot just be aware that it does have a few UI quirks that you'll need to familiarize yourself with. Specifically reordering tab groups is, at the time of this review, found in Settings > Options > Sort Containers. It would be very nice to be able to drag the containers for ordering purposes.

公式のアドオンよりも機能が充実していて使いやすいです

Great addon, please keep updating it!

最高のタブグループアドオン。Panorama View の強化が欲しいとは思うが。最高

As best as I can tell this is the only tab group addon that allows you to have multiple tab groups open at the same time.
There's some features that can be done more nicely and bugs to fix but I'm happy it exists.
Currently seems to be lacking a neat "move to container" feature

BRILLIANT ! !

I was looking exactly for an addon which enables tab grouping only via Containers. That's why I used the addon "Conex" before, which isn't developed anymore since 4 years and is buggy. Thanks so much for this addon. It's the perfect replacement for Conex.

It feels and works like a clone of the tab grouping feature Chrome is using. Your addon is minimalistic but feature-rich.

Please keep it up, awesome work!
