Everything looks good only nitpicks i have is that when switching container groups it's a bit slow when there's over 50-300 tabs in it and pdf/html files that opens a new tab and the addon page/about:config in firefox switches the container to default container tab instead of opening it in the current container.

I became totally dependent on Panorama/Tab Groups functionality, so I really welcome the effort to bring it back in webextensions! A major milestone has been reached as tab hiding now works without any hacks in Firefox 59 Beta 3! No need to fiddle with a Nightly build anymore, Beta is almost release quality! And I can finally retire the ESR version that I kept for compatibility with old Tab Groups...

The only tweak I'd do now is to enable switching to another group/container by simply clicking on it, without the need to "unwrap" it and pick a particular tab (just like the old Tab Groups - left part of the list item goes to group, right part with number of tabs unwraps it).

Thanks for this invaluable tool!

Edit: Just realized that Fx59b3 is not officially out yet, I tried a candidate build. But it will be released soon.
Edit2: Thanks for promptly implementing my suggestion, upgrading my rating from 4 to 5 stars!

Une bonne idée, mais pour le moment encore trop limité.
Il faut toujours utilisé Multi-account-containers pour créer les containers et la partie tabgroup n'est pas encore de la partie.
A suivre

Note : Avec FF57.0.3 ce plugin consomme beaucoup de mémoire : 1Go !!! J'ai du le désactiver à cause de cela.

A good idea, but for the moment still too limited.
Multi-account-containers must always be used to create containers and the tabgroup part is not yet in the game.
To be continued

Note: With FF57.0.3, this plugin consumes a lot of memory: 1GB! I had to disable it because of that.

didnt find hotkeys for opening pop-up with search and containers

Does what it says on the box. Not buggy even though it's in active development. I'm running the fully enabled Nightly version, and it's a great replacement for Tab Groups. Not quite as user friendly but it's manageable. I would love the ability to move multiple tabs at once to a different container/group without having to switch to that new group immediately. Starting off trying to organize a couple hundred tabs initially lumped in default is quite a task when it has to be done one by one with 5 clicks each, but once that's over with it's not bad except for the odd time I forget to switch groups before opening more tabs then I have to move a few over at once. Functioning keyboard shortcuts would also be nice, I would prefer that to the big GUI organization screen that the old tab groups had. Another thing is I'd like the private tabs container to not be visible on the container selection interface by default, I don't use it and I don't appreciate people looking at my screen being able to see that and assume that I often do. Overall: good shit, keep it coming.

Edit in 2019-05: Also when there's more than 11 tab groups (including 'default') you have to scroll down to see the last one, the tab group selector window doesn't just get longer, which is kinda annoying, it looks like it should be able to hold 4 more within the length of the firefox window if the menu was as long as that. I'm using a standard 1920x1080 screen

Good start I guess but this extension just feels completely broken.

In the extension preferences, there is no way to set the radio button for "Moving tabs menu" - there is no save config and that setting is never persistent after leaving preferences.

I have "Enable moving tabs between containers" set to "yup".
And yet moving stuff from one container to another doesn't work. What's the mechanic, a context menu on the tab itself? Not there. Dragging? From where to where? Attempting to drag from within the little Conex dropdown doesn't work.

In short, my Conex experience is having all my tabs assigned to "default". The only benefit is being able to search among tabs.

Good start.

Would need to actually switch groups into different windows, for now all it does is tag them by color into the same window. Also add an option to change the group names.

Will keep on checking the updates.

A great start. It would be even better if some of the options were moved closer to the user, such as group renaming, re-ordering, etc. Instead of being in the options page, they should be part of the menu that pops up by clicking the Conex icon. Also, when I click on a group to expand, scroll bars on the side and at the bottom will come up. There should never be a scroll bar at the bottom. All that said, your add-on is the only reason I kept Firefox instead of jumping ship. Thank you so much for taking the time to code it!

Great Extension. Gives ME all that I was missing from tabsgroups( even if mozilla says container arent the same - you made it the SAME - THANK YOU). Just waiting for the webextensionAPI be "extended" by mozilla to Hide the containers;).
Once AGAIN GREAT WORK and a big thanks

Ignoring the yet missing webapi that prevents hiding this has everything I need including a way to search your groups.

Please correct this bug and let us use it in FF57+ so we have an alternatives for TAB GROUPS extension

Edit: info for the developer, I have 500+ opened tab with FF57, and tab groups plugin disabled after ugrading from previous FF version, I can only see one groups, but other tabs are opened and hidden.

Thanks, for your reply, I know there is a firefox bug, I give you 5 stars waiting the bugfix from mozilla.

I think it would be better without containers, they are intended for online identity but here they are being misused for grouping.

If it had the over view for tabs then it would be perfect. I'd also like to see a more intuitive way to move tabs between groups. Otherwise it does a decent job at replacing tab groups.

I've been using the addon for some time now and I am better at using it. I still long for the old Tab Groups functionality but Conex is filling in most of it. Kudos to the developer.

Please keep this great effort, definitely THE reason why I dont completely switch to Chrome

Nice try of tab group.
How do you assess the chances of hiding the tabs at this moment?

Nice job on this one and thx a lot for making import from tabgroup :)

It saved my day - after update to FF 57 all my pages from TabGroups were lost, but after installing this plugin they appeared again in the "Default" group!
Thank you very much, I'm now going to learn to live with the "Containers" idea, it looks like with Conex it could work...

How can I delete "default" container?

is it possible to add the ability to add and rename folder name ?

Five stars.

Bugs should be expected whilst this extension is explicitly experimental. Some of the technologies used, or to be used, by this extension are quite novel – or not yet provided by Mozilla … and so on.

Whilst it's not intended for use with anything less than Firefox 57.0a1, I do use Conex with 56.0.1 – and expect to continue with 56.x until the August 2018 release of Firefox 62.

Special attention to a preference that can be chosen when beginning to use Conex – "don't care about privacy" – I do care. Simply:

- in the Firefox profile where I allow carelessness with Conex, I will not use Firefox containers for anything privacy-related.

(There's just one container – used for testing the new front-end to addons.mozilla.org – entirely unrelated to privacy.)

Conex is, amongst other things, useful for switching tabs. I currently use it with more than one thousand tabs in seventy-something groups (the traditional Tab Groups extension) across fourteen windows. Hint:

- it's sometimes easier to switch tabs with Conex than with Mozilla's address bar.
