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.

Seems to work great so far, but I have a few suggestions.

Currently it doesn't appear that your settings sync between devices. I've got FireFox installed on both my work computer and my home computer, logged in on my personal email and everything synced between the two. I spent some time last night setting up my containers, and setting certain sites to only open in specific containers, etc. When I logged in on my work laptop, it shows all the original containers (none of the new ones I setup), and when I visit certain sites, they don't default to the container I configured on my home computer. This functionality would be great to have.

Another suggestion would be able to move an existing tab/site into a container. When I installed the addon, I had several tabs open. I had to open a specific container tab, then copy/paste the URL from the generic tab, to the container tab. It also doesn't appear to let you move the tab from one container to another.

I'm still getting used to the addon, so maybe this little nuances aren't as big of a deal, especially as I setup some default behaviors, but for me the biggest thing would be addon settings/containers syncing across browsers.

Edit: Oh, once you get the syncing of settings across devices, enabling this addon for mobile use would be awesome.

Fantastic extension. I no longer need to run multiple browsers, I am now strictly a Firefox user.

Feature suggestions:
Allow manually entering websites.
Allow randomizing browser fingerprint per container.

Great idea. Facebook and Google have been isolated. However, I think it would be more intuitive if you could right click on the tab and click "Add to Container X" rather than first having to open the tab in container.

Also, what are the advantages of using this versus having tracking protection enabled all of time?

Good start but needs more work. Mainly I want to tie certain sites to certain containers, at least for bookmarked sites. For example, I want my banking site automatically open in the banking container every time. Currently the process to do so is somewhat cumbersome and has to be repeated every single time. That's quite annoying.

Step 1: Firefox Multi-Account Containers

Step 2: Firefox Browser Profiles!!!

I love it. If only it worked on Firefox for Android... it would get 5 stars.

genius! Please make this as an default feature.
an opion to say a bookmark should open in a container would be great.

Very nice way to use separate profiles side-by-side.
However, it would be nice if the container could be specified in bookmarks. More specifically, in bookmarks that are supposed to open in the side bar. Those now always appear to use the 'no container' profile.

I like it.
