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.

Almost perfect.

Tento doplněk mi přijde úžasný. Narozdíl od jiných doplňků, které mají zajistit soukromí a znemožnění stránkám vás sledovat je zde jasně vidět, co dělá. Bohužel je zde ještě spousta práce, kterou je potřeba udělat, aby si zasloužil 5 hvězdiček. Synchronizace mezi zařízeními je nutnost - nebudu trávit hodiny času učením prohlížeče, jakou stránku zavřít do jakého kontejneru opakovaně. Pak by bylo fajn mít nějaké UI na úpravu nastavení - např. mít možnost vypsat si stránky, které patří do jakého kontejneru by jistě ušetřilo práci proti současnému řešení, kdy člověk musí stránku otevřít v daném kontejneru, označit jako 'Vždy otevřít' a pak nejlépe znovu načíst, aby toto nastavení potvrdil.
Jen tak dál vývojáři!

Really nice add-on but I will put 5 stars if you add the "hide container eye" directly on each line of the container's list ; improvement for hiding with only 2 clic. Thank you.

Very nice but it is annoying to ask twice to remember the website assigned container by default. Why?

Great for privacy, great for multi-account access. Does what it says on the box.

To improve:
- Remove the "Open this site in your assigned container?" step, it's completely unnecessary. I've already said I want it, so do it.
- Allow (specific) extensions to work across containers, because I have to re-enter my LastPass password every time I open a new container, which is annoying.
- Ability to sync container config with Firefox account, for multi-device access.
- Ability to edit containers more efficiently, much like one would bookmarks. I'd like to be able to copy a folder of bookmarks and paste them into a container all at once.

Five stars if you save the containers and config for the site on firefox account and sync...

This is a really great extension that makes life much easier managing multiple clients.
What would be helpful in the future are adding key-bindings and synchronisation.
But again, great tool that I now use everyday. Thank you!

It needs sync to be able to be the same containers across all my Firefox installations on all platforms.

It doesn't sync. I would like to share the same container types between my computers. I have a Mac and a PC.

Great extension. What keeps me from giving 5 stars is that the keyboard shortcuts need to be mappable. It should be one command to open a container tab.

Very useful indeed! But I did notice a little problem. When I was in my Personal tab and span a child tab (also personal) to a Medium post as anonymous, one of my cpu cores goes up to 100% load.
That happen every time I spanned the Personal tab with this Medium post.
But, when I opened up the exactly same site on a regular tab (also as anonymous), the cpu was just fine.
So, I logged in at Medium in the Personal context, and the behavior was gone.
That happens on a Firefox Quantum in a Linux Fedora distribution.
