It simplifies my work a lot, since I can use only one browser now and it's super convenient.
Thanks to author for such a great plugin!

Very nice idea. But it would be a perfect addon if the source code would be available under an Open Source licence... Would it be possible?

If one wants to organize her browsing around a specific set of "persistent" containers ( like the standard Personal, Work, Banking & Shopping ) she can use, for example, 'Firefox Multi-Account Containers' or 'Sea Containers'.

'Containers on the go' takes another approach by creating new non-descript "temporary" containers, beyond the range of the "persistent" ones, named 'CG 1', 'CG 2' etc.

A nice thing is that both 'Firefox Multi-Account Containers' and 'Sea Containers' can "see" and use the
'Containers on the go' containers. 'Firefox Multi-Account Containers' can even edit/delete them.

Looking for a replacement for tab groups AND Private Tab. This has some nice features, especially with the addition of the Conex add-on. I wish however that you could create a TRUE Private Tab, such as the add-on "Private Tabs" did.

perfect addon, would have written it myself if it didn't exist already.

that said I have one idea to increase usability even more: automatically create containers based on the domain
so basically a second mode where containers are created when you open a new tab and it's a new domain, or assigned to an existing container if one exists for this domain (including subdomains).
might be a bit problematic with redirects maybe, but it frees the user from the need to check the domain before deciding if it can be opened in the same or a new container.

just something to think about. good work in any case!

It's a great addition to Containers Extension. However, it is no longer released under GPL. Also author doesn't provide release notes.

Edit:
Thank you for the release notes. I reconsidered my opinion. This add-on deserves 5 stars despite proprietary license.

Why is open source license important to me as an user? It's because it happened too many times that I've been using some proprietary software which has been abandoned at some point or the maintainer decided to ship some crap with it and make it much worse. If something similar happens to open source software there's always someone who creates a fork and I don't end up looking for alternatives (which often do not even exist).

Edit2:
I'd like to suggest additional feature. Right now this extension provides an option to "Open link in new container" in the context menu for hyperlinks only. It would be nice to have this context menu option for selected link that is not a hyperlink, just like you have "Open link" option that Firefox gives you.

The combination of a novel and rapidly evolving technology (Firefox containers) – plus an array of extensions that are novel and in some cases immature/conflicting – deserves reasonable attention to detail. The inherent contexts of privacy and security increase the desire for attention to detail.

Postscript: I edited this review and upped the star rating in response to a pleasant and very prompt response (below) from the developer. Thanks!

(The first edition was critical of the absence of release notes.)

Using Firefox 57, IndexedDB entries are not removed when using a container after closing the tab.

Excellent extension. Extremely useful.

A couple ideas:
1. Start the browser in CG 1 instead of the non-container space.
2. Have the new tab (+) button open a new tab in the current container group.
3. Upload to a source control website like GitHub.

This was actually was one of the most requested features for the Test Pilot experiment. Would you be willing to upload to a source control website? I would like to fix the changes we are making in Firefox 57 for when containers are disabled.

Feel free to reach out to the containers team: containers@mozilla.com

update too frequently.

Loving the addon, good way to keep sites from setting data permanently in localstorage.

I have a request, could you make the Alt + c shortcut make the address bar get focus? I'd like to be able to type into the address bar after opening a new container just like I can when I open a new tab with ctrl + t.

Thanks

Is bretty clever and make private.

Can function like private tabs
