I just love what this extension does, preventing cross-talk between activated Container tabs! There is one, rather large, caveat, however, in that when initially setting up a URL in a designated Container, it easily completed, and it looks like you're done! BUT... the next time you use that URL (say you Bookmarked it), you are presented with a Container verification screen, where you have to say, "Yes, I actually DO WANT to use the Container that I thought that I already HAD set up!" What this means is that once you setup a URL to a Container, you have to immediately TRY that URL (possibly Bookmarked) to answer that verification page. THEN...everything works as expected. I consider it an inconvenience, but once you are used to jumping thru the hoops, its 2nd nature. And that does not detract from the purpose or function of the extension!

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

Please change environment bonds to Deep Links instead of only Top Level Domains. Ask whether the container should always open up when the current deep link is opened or whenever any site of the top level domain is opened.

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
