This is a great tool that I use everyday to sepperate personal from work, secure from face.. insecure and so on.
My only issues would be that when I open a site from default I cant then assign it to something and have it moved to that tab, my second issue is that after I set something to always open in a container I will get the notification on next launch asking if I want this.

Other wise this is an amazing tool.

Bugs: (None so far)

Cons:
- No dark theme compatibility, it's almost invisible on dark backgrounds.

Pros:
- It's fairly straightforward to set up; and once set up you can forget about it

I like the functionality, but I don't like one behavior. I open a work tab to open gmail for example, but it reopens the site in personal container, which is annoying. If I am in a container specific tab, especially a new tab, the site should be opened in the same container.

I will not longer be able to live without this extension.

Things it really needs:
- syncing between Firefox instances
- a better icon for dark themes (it's invisible)
- more colours and icons for tabs

This is a very nice tool. Removed a star because it does not sync between my PCs using Firefox Sync.

Bug: Infinite loop for auto-open websites.

I have amazon.com set to open up in a "Shopping", and aws.amazon.com set to open up in a "Cloud" tab. When signing in to AWS, the tab gets stuck in an infinite loop of switching back and forth between a "shopping" tab and a "cloud" tab.

Would be 5 stars if container info was synchronizing with firefox account to other computers

在“Open this site in your assigned container?”页面，选择后一个选项时，极大概率会出现点击无效果的情况。

Very useful! But I would like to be able to sync the configurations between devices, and to have the choice of some predefined rules. Such as "every google page in a Google container". Also, I have a bug when I create such rule on a google page, and that I have a page that automatically redirect to another container page. The new container page is indeed opened in a new tab, but the previous tab is not closed...

Excellente initiative pour "compartimenter" les connexions !
I agree totally to following proposal : "The expansion is really great. But please implement the settings in Firefox Sync or make them exportable. It would also be great if you could right-click on a tab and assign the page directly to a container "Always open page X in container Y".

Works amazingly well. Could have better options of customization for container icon and color.

The expansion is really great. But please implement the settings in Firefox Sync or make them exportable. It would also be great if you could right-click on a tab and assign the page directly to a container "Always open page X in container Y".

great tool but please add FIREFOX SYNC. It's a pain to set up your containers for every machine.

Really helpful, especially since I have multiple O365 clients. Be aware though that settings don't seem to sync across machines, and there's very little you can change about the containers view.

It's a great tool for privacy but please add FIREFOX SYNC. It's a pain to set up your containers for every machine.

Such a blessing! Especially in combination with the keyboard shortcuts add-on. Would be greater still if containers set up would sync over the Firefox profile to keep them in sync across devices!

I realy love this extension, it's what I always searched for!
One feature that I'd love to see is the ability to map containers with firefox accounts.
By that I mean I have a personal firefox account with a set of bookmarks and a professional one.
Firefox containers kind of overlap with firefox accounts. On one hand I can access all my bookmarks and on the other one I can separate concerns easily.

Maybe I'm missing something but that would be awesome instead of going about:profiles everytime.

Wonderful tool for keeping your browsing efforts separated and fenced off from nosy Bots.

Seems like I had to do three things to make reopening in the right container "auto-magic";

Open a new tab in the "Amazon" container (long click on '+'). Past the URL into the new Amazon container tab.
Click the Multi-container symbol and select "Always open in Amazon"
Open a non-container tab and paste the URL, select "Remember my decision to always open in Amazon container"

After all 3 of these steps are done, the URL will always open in the selected container.

Once these 3 steps are done you're all set. However there are currently 2 things missing from this and other "container tools";

1. Easy Export/backup/restore/Import of container rules. It would be lovely if this capability were available in CSV and JSON formats. [Necessary for setup of multiple machines without Sync, and off-site storage of config(s)]

2. An easy way to Edit container rules beyond just delete and start over. This will allow quickly changing custom behavior(s). #1 might take this issue toward "feasible".

I put my own website (with multiple applications) in a container to keep nosy bots out of my site cookie jars.

Great idea, love having this feature. I'm tired of having everything I looked at on Amazon.com show up in my Facebook feed. This is a win for privacy and giving browser experience control back to the user. No other browser appears to have these tools, just Firefox.

Excellent idea, but i can't actually use it without analogue in mobile browser.
