We have been making good progress on this since we released Profiles last month.
Here is the the full functionality speced out in this mockup. We call these Session tabs as it makes much more sense thatn Containers. Feedback appreciated! Enjoy!
One thing that I find missing in Firefox's container tabs is the ability to sort my containers into folders or groups. It would be really nice if Orion had some sort of folder system for sessions tabs.
Looks really nice so far!
behaviour request: New tabs opened from a current session would inherit the same session. For example, CMD+Click to open in a new tab would have the same session.
as alastor57 said here, i uploaded a screenshot on how Tabs can be Sorted by Container, so you dont have to look at everytab to identify on what container is it running
See the screenshot
I am so excited to see you’re working on this. Switched from LibreWolf and this was the last thing missing. Bravo!
You’ll be getting my money soon.
And yes, the name Sessions is so much better than Containers.
One of the major benefits to me of container tabs in Firefox/librewolf is the ability to specify a proxy, such as a vpn location. Could this be added to the feature list please? Then it’s truly complete for me.
Vlad Yes, I understand it is generally handled at OS level on macOS.
Firefox has, with an extension, the avbility to specify separate proxies for each container. This is useful for VPNs.
I believe therefore it is related to containers in this case. Something I would love to have. Thanks!
Done via Profiles
TheOtherKai Not really, we want to support sessions(containers) too.
Vlad One thing that I find missing in this is the ability to assign a session to a saved window.
If that could get implemented along with the rest of what you've shown, I think I can switch to Orion full time which is really exciting since I've been stuck ping ponging between Arc and Firefox + Sidebery.
GreyAsteroid How do you do it in Arc?
Vlad Arc uses profiles that work like containers instead of what Orion calls profiles. There are "spaces" which would be the equivalent to Orion's saved windows and through a couple different menus the spaces can be assigned a profile.
This allows easy switching of containers via the space switcher at the bottom of the sidebar.
I should note I'm using the canary version so I'm unsure if the stable version is different atm.
GreyAsteroid Hm those seem to be profiles? Container tab allows you to open a tab in your current window that belongs to a different isolated cookie storage. I do not think Arc can do that? It feels like you are asking for a different thing?
Vlad Ignore the name profiles. They do not function as Orion's profiles do, they function as containers do.
For example,
While being in separate "profiles", these 2 spaces share extensions, bookmarks, etc. but cookies are not shared.
GreyAsteroid To clarify further, I'd like to be able to assign a session to a saved window in Orion to mimic the functionality of Arc/Firefox+Sidebery.
GreyAsteroid Thanks but I do not think this is what is being asked in this thread. Users are asking for Firefox style containers/container tabs, which allow you among other things to have tabs from different containers present in the same window for example. Again I do not think that is possible in Arc?
Vlad 
Yes this is possible on Arc but I'll use Firefox + Sidebery as an example instead to make it easier to understand.
Sidebery on Firefox lets me assign a container to a tab group. In this video I switch between two tab groups, one in the default container where I'm logged in and another in a different container where I am not logged in.
In this video I switch between the same tab open in two different saved windows. I'd like to be able to assign a container to a saved window so that new tabs would be opened in the container assigned to that saved window.
If you'd like I can make a feature request for this specifically but considering it's functionality based on a feature not present in Orion but being requested in this thread I figured I'd post about it here.
@GreyAsteroid
you're asking for something different. let me clarify:
arc's profiles are a wrapper around chrome's profiles. but, they do sort of "sync" extensions, but not quite.
they merely install extensions to all profiles when its installed in one, and uninstall extensions when uninstalled in one of them.
if this were the case, you could disable an extension in one profile, but it wouldn’t be disabled in another, as shown in this video (these are two spaces, each in their own profile):
tl;dr, arc's profiles are indeed profiles, and act as orion's and chrome's profiles, in the way that cookies, tab history (trivial to test this), extensions, etc are separate.
i won't talk about bookmarks/favorites, as arc does not have bookmarks/favorites a la chrome.
@GreyAsteroid
this post is about firefox-style containers, meaning cookie isolation between certain tabs, in one window/set of tabs, without any sort of switching, essentially:
(crude drawing, but i think it does a great job of explaining what container are)
chrome-style profiles, on the other hand, are about cookie, bookmarks, history, exension, etc isolation across separate windows/sets of tabs, with some switching between them.
basically:
(also crude drawing, but i think its accurate enough)
