Works well for my use (on a single machine). I haven't used the sync-option! Other reviews report it is buggy...

Ajuda muito quem precisa acessar vários de logins diferentes, mas a sincronia tem problemas.

It was miraculous to use, but Mozilla does not care to develop or run anything without illegal corporations telling them what to do. Who agrees? Is the Internet not a conspiracy?

Irresponsible to have this extension published and available with such dire bugs. Whatever you do, DO NOT turn on Sync for this extension. You'll end up wiping out your entire configuration, your containers, your site rules, everything.

Needed to have multiple Web Outlook email accounts open simultaneously. Worked great. If pinned the accounts came back up without logging in again if Firefox exited and restarted. Would be absolutely perfect for me if the accounts came back up after a Restart.

Doesn't work well containing Google, can't sign in on gemini.google.com

Guaranteed to silently drop containers in the middle of your workflow, with no github interest in even acknowledging the problem.

syncing is pointless. i'm done setting up site lists every time it resets when logging in on new devices.

The Firefox Sync integration is horrible - it keeps merging back old changes. Container settings get reverted, and old removed containers come back...

This extension needs some work before it fits the concept. In situations where multiple accounts need to be managed on the same website (using multiple microsoft accounts for different clients, for instance) , it is generally not usable. The following workflow breaks it:

- Open tab in X container, login to a service
- Service uses redirects to authenticate, container extension grabs those redirects and loses the container status or changes the container status, breaking the login flow or putting a different login into the context

Additionally, there does not seem to be an option to remove a site from a container preference, once added.

De ideale manier om met meerdere accounts en een domein te werken zonder van profiel te hoeven wisselen.

This extension is 100% what's keeping me on firefox

Works well for seperating my tracked internet history, without needing to setup a second Firefox Profile & Mozilla Account. This in addition to the Facebook, Google & Twitter Containers help keep those 3 from tying everywhere I go on the 'net to my accounts.

Really helps at keeping some of the problematic sites contained. Could use some polishing but very useful addition.

this is the god extension for me. my life saver please continue. dont stop ever. i love you firefox

This is great in concept, however, the friction kills it for me. After adding a site to a container, whenever I now open a link of that site, I get asked whether I wanna open it in that container. Of course I do, I mean, I manually added it to that container. This only needs to be done once per site, but it's still unnecessary friction that just about tips it over to "more pain than gain" unfortunately. Please make an option to always open a given site in it's container no matter what

This is very powerful tool for productivity. I shifted from Chrome to Firefox a week ago.

This add-on works very well and I use it every day!

However, there are some things that I think could be improved:

First, when opening a webpage that has a container assigned, I get the choice between "open in current" tab and "open in x container". I would like to be able to select from all my containers directly on that page.

Second, when reopening Firefox, all tabs that get reloaded when clicking on them triggers the "choose container" page.

Also, choosing the option to not open a new tab for container pages led to some weird tab interactions, but I can't remember exactly what happened.
