Un outil plein de promesses, mais pas encore au point. Divers plantages et bogues, et surtout des fuites de mémoire qui ralentissent progressivement FF (et le PC) au fil du temps. Mais pour ce qui est des fonctionnalités, c'est tout à fait ce qu'il me faut (faudrait).
Merci !! et continuez à progresser, hein !! :D

From a feature point of view, this is great to isolate workflow context in a single session. However it's rather greedy in memory, and session restoring incovenient as everything will be restored in a single session.

Nice job.
We almost are back to TabGroup (still missing the tab panel).
Another thing missing is the assignment of a complete domain to a container;
The assignment seems to be done site-wise only.

Hi great jobs with the addon.
i have a question, in the large menu, in the expand countainer list, is it possible for the order of the tabs to appear in the order they are in the countainer? It seems that they appear in the order of last access, if I am not mistaken.

Regards and good work

Great work man! You're a life saver :) Or at the very least a tab saver!

Your add-on has pretty much all the features I'm looking for.

Only thing missing that I've seen so far is opening links into the same tab group you are currently in if you're opening them from a pinned tab. They seem to always open into the default group regardless of which group is active at the moment.

Finally, something that allows you to comfortably work with Firefox after 57.
A very nice combination of contexts with grouping cards. Still far from the functionality of Tab Groups, but this is due to the limitations of the current api and not the extension itself. Conex, by the way, "squeezes" almost everything that is possible from the current api.
Most lacking feature is synchronization between devices (but again, this is probably a limitation of Firefox contexts, not the extension itself).

Great idea. Usually a great addon. One question: The open tabs are not shown in the real order? They seem to be diced.

Works great, thanks for this.

As a Panorama/TabGroups user i was waiting for an addon that would have the same core functionality. The wait is over. I've finally been able to switch from ff56 to new ff Quantum with introduction of tab hiding API and the help of Conex.

[UPDATE March 2018] With the last updates, most of the bugs and weird behaviours are gone, and this little tips list is now unnecessary. I'll leave it for future reference, to show how much work went into making this excellent add-on.

[Original Post]
Hello all,

I switched from Firefox ESR to Firefox Beta to try out Conex when it seemed to be a proper replacement for Tab Groups. I'm satisfied with Conex and will not move back, but if you're in the same situation, I would suggest waiting a little bit more than I did, at least until Firefox 59 goes to the normal release channel. Conex is working fine and getting better quickly, but there are still a few UX issues to be ironed out. Still, it is already a good solution for those who want to update to Quantum and keep their tab groups.

If you want to make the same switch, first you'll need to get Firefox 59, which is the current Beta version:
1. first, backup your Firefox profile, just in case something goes wrong: https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles
2. backup your Tab Groups data in the options of Tab Groups
3. download and install Firefox Beta: https://www.mozilla.org/en-US/firefox/channel/desktop/

Now to Conex:
4. install Conex from this page, and accept all the permissions (including the extra ones in the Conex settings screen that will appear after installation)
5. manually enable tab hiding in Firefox: in the location bar, type in "about:config", filter for "extensions.webextensions.tabhide.enabled" and set the value to "true"
6. Use the "Import Tab Groups backup file" tool, found in the Conex Settings (right-click on the new multicolor icon, top right of Firefox)

You're all set! All your groups are back, with all of the right tabs, even in the right order! When you open a new tab, it will stay in the current group, everything works fine with the context menu or middle-click methods, just like you'd expect.

Some other things work differently, so to use Conex to actively manage your tabs there are a few tricks you will need to know:
- Groups are now renamed "containers", a new feature of Firefox Quantum that allows some of the same uses. Conex builds on that to make them actually useful. But from this default feature, you will find a new option in the links contextual menu named "Open Link In New Container Tab". It lets you open the new tab in any existing container, but you cannot create a new container/group from this option, despite the name. It interacts in a funny way with Conex (the tab takes on a "quantum" nature, by being in a superposition of two containers at once until you click on it), but it is functional.
- To remove the default empty containers created by Firefox, to add new containers or to rename them, the only way I found was through the containers preferences menu. Type "about:preferences#containers" in the Firefox address bar to access it.
- to move tabs between containers is tricky. There is no access to this option through the right-click menu on the tab, and the Conex shortcut (CTRL + SHIFT + e) is in conflict with the Windows global "change keyboard language" shortcut. It doesn't work in my case, it switches my keyborad between AZERTY and QWERTY instead. The only way to move a tab between containers at the moment is to right-click the tab in the Conex list (left-click on the Conex icon to access this list), go to the Conex contextual menu that is only found there, and move your tab.

To conclude, my sincere thanks go to Kesselborn for creating Conex, which is really helping out the last of the Panorama (remember that?) users, who already had to exile themselves once to Tab Groups when Mozilla killed their own feature for no reason. Quicksaver (creator of Tab Groups) and Kesselborn are doing us a huge favor with their add-ons, with all the work they represent, and have all my gratitude!

Fabulous. Lifesaver. Sanity keeper. Thre are no words.

Years have passed by (was it really 2018?) and still I am indebted for this addon. It is the bread and butter for my life breakfast, it's my morning sunshine and red evening clouds!

thanks

Hi! Thanks for developing this; at this point (with tab hide functionality), it functions almost as well for me as Tab Groups did before, and this is what actually prompted me to upgrade to quantum. But there is one pet peeve of mine that is hopefully not too hard to fix. I middle-click on my bookmarks toolbar all the time, and new tabs with links from the toolbar always open in default container. Would it be possible to change it to be consistent with opening an empty new bar, which already happens in the container you're currently in (maybe not as default behavior, but as an option)? Also, would it be possible to have the container drop-down menu that is sorted in any other way than alphabetically?

Edited, since I guess one can't post answers to dev comments. :-)

Edit: well, I guess ideally one could arrange the containers in the list by hand, through drag-and-drop or any other way, but even the order they are in about:preferences#containers (which is, I guess, the order of their creation) would be fine to have.

The fact that tabs and links spring open in the *default* container rather than the active one you're currently working with, very nearly makes this unusable for me. I'm still deciding whether I should persevere with it...

I've installed 'new container tab' addon, but it still means that the standard keyboard shortcut, CTRL+T, that of course everyone is used to and which you're still bound to hit by instinct, makes it suddenly hide the container you're working in- ie. all your other open tabs- and show the new tab by itself. Now, that's BEYOND annoying and I'm really not sure it's something I can accept I'm afraid.

The issue is referenced here: https://github.com/mozilla/multi-account-containers/issues/462

EDIT: Downgraded to one star after puerile response from the developer. I've re-read what I wrote and stand-by everything there. It doesn't seem overly rude, it was meant as, and clearly is, constructive criticism to help others decide whether to install this addon. Grow up.

Nice hiding the top bar with FF59, but not working with tree style tab
