It is obvious that having silos, or isolated brower sessions per tab is a good idea unless you are fine with being tracked about the web.
This solution for Firefox works well for me, as far as I can tell, and is relatively easy to use. It takes some time to setup and each website you visit belonging to an organization that you want to put into a specific container needs to be placed manually into that container (you can't seem to set a wildcard via the front-facing interface?).
But when done, you just surf and tabs open up naturally and all that you've asked to be isolated is: just as I'd want its functionality to behave.

This is a great start. A few small changes would make a big difference. If there was a way to set one container as the default where all new tabs (unless specified otherwise) went into that container, that would be great. Most of my tabs are work, so it would be nice to have that be the default one.

Also, I'd like it to automatically reset a tab to a certain container like it does to facebook, just by what site I went to. For example, I'd like that same functionality for facebook to apply to Twitter, Pinterest, and other social media. If there was a way to integrate sites that are saved as bookmarks with containers, that might be a great way to do it.

Keep up the good work on privacy. You're the only group that seems to be doing it.

Very much follows the spirit of "Tab Groups" from the old FireFox.

However, a list of critiques:

- Support for FireFox Sync is almost mandatory for next update priority. The lack of being able to sync my container definitions between all my PCs is going to be deal-breaking if it's not addressed.
- Tab Right-Click assignment of container group.
- Wider range of colors and icons would be nice.
- A better customization experience for power users to control how sites and tabs are categorized, and the edit process for container definitions.

You're on the right track. Please listen to the feedback!

Great addon. One thing I would like to see is the option to only open new tabs in containers for sites that have them assigned. If I open a link from a Google search, I don't want it to remain in my container for Google, even if that means forcing them to always opening a new tab.

Very good add-on. Two extra functionalities would be helpful. First, the ability to sort the containers alphabetically or just rearranging them. Second, synchronisation across different computers.

it is good at protecting privacy, I use it to put facebook in its own container. I hope that all tabs can be put in containers automatically instead of opening them first and then search in them.

Very useful extension, with a few shortcomings:
- no integration with the Third-party Cookie setting -- if I only allow 3rd party cookies from sites I've already visited, ideally this is localized per container (so if I have visited SocialNetworkA in its own container, I don't get its cookie when visiting SensitiveSiteB in a different container)
- not being able to reorder containers -- as I create more and more containers, it's getting to the point where I want them sorted alphabetically, but that's not possible unless I created them in the right order
- container icons a bit limited - would be great to be able to use a specified domain's favicon as the container logo

Please add the ability to synchronize our containers across our devices / account.

If this isn't possible to do easily / safely, then please add the ability to export and import the configuration, so I can copy the config manually.

Thanks

I love it and use it everyday. I just wish the keyboard shortcut (Ctrl+Period) was customizable.

Great stuff! Only thing I miss is, that you can assign whole domains (incl. all subdomains) to a container, rather than just specific (sub-)domains.

Separating by site name is good, but more fine-grained control would be appreciated: a preferences page where a user can edit the match rules to any regex: Personally, I want to open reddit.com/r/a in container a, and reddit.com/r/b in container b.

Also, it loses my data fairly often fairly often. Either making the extension more robust or allowing us to export/import data would be great.

It would be 5 stars with the ability to change the order of the Container list and (I just found this out by looking at a few of the reviews) the ability to sync to other devices!

The ONLY reason this isn't a 5 star review is that there's no way to sync containers across multiple devices. Other than that, it's great!

I like it, good way to organize and separate multiple domain surfing.
Although, It's missing some features, like:
+Clearing the browsing history for a single Container.
+Make a Container like Private Mode, doesn't keep data.
+Overall some more stuff regarding privacy by container.

Seems like a great idea and I thank Mozilla for creating it. My only problem is, even when I click the box saying, "Always open in..." the specified container. The next time I go to the site, it somesimes stays on the default container.

In other words, it would be nice if containers were automatically detected every time we visit a site that was placed in a container.

When I first heard about this I thought of how I would sandbox facebook from accessing my other data. Worked perfectly well.

I would have given it a 5 star if there was a way to remember the settings. Maybe an integration with firefox sync

it'll be good if we can open bookmarks in selected container by right click > select conainer.

Please add Cloud Sync of the Containers! Hate to add them each time

very good concept. simple execution. more features would be good.

Suggestion:

Currently:
When you open a link in "Tab 1 - Container A" that is set to open in Container B, the link opens in "Tab 2 - Container B).

Improvement(?):
I think it would be better if the link opened in "Tab A - Container B". Meaning that (Tab 1 - Container A) changes to (Tab 1 - Container B)

Second Suggestion: Fix to a bug? = sometimes when I open a link that opens in a new container, 2 tabs open instead of 1

Only reason I don't give it 5 stars is because It doesn't sync container settings between devices.

NIce add-on, but one thing I cannot seem to do is to pre-define websites to open in different containers so I don't have to choose container every time I load that website. Perhaps I have missed something.
