- disabling and re-enabling the plugins deletes the complete config
- every now and then the extensions asks where to open an URL although it is already configured

Great idea. In the end it does something a browser should do naturally.

Every once in a while, all of my containers are lost and I have to start over. That needs fixed.

YOU CANNOT REMOVE MOZILLA VPN INTEGRATION THROUGH THE UI IF YOU UNSUBSCRIBE FROM MOZILLA VPN.

TO REMOVE, REPORT ADD-ON FOR ABUSE THEN RE-INSTALL.

This add on has too many issues. The idea is great, but it keeps opening websites in the wrong containers, it doesn't let me manage what websites to open in what containers and the "Remember my decision for this site" checkbox does absolutely nothing. It keeps asking to open the website in the wrong container every single time I open a new tab. This add on doesn't make life easier, it's just one big frustrating obstacle. It's easier to just open a second browser.

This had been wonderful but for the past few days it keeps adding dozens of new containers without me doing anything.
I delete all the containers that I didn't create but they will just reappear. Sometimes it's seconds later, some times it can be an hour but inevitably they do just appear again without going anywhere near.
Shuch a shame.

This is one of the "killer features" for me that have me use Firefox. And when I upgraded to FF 103 it was removed along with all my containers! :-(

All it takes to lose every single bit of personalized configuration is to toggle disable by accident once.

And I thought it was supposed to sync the settings back regardless?

I'm done with containers. Great idea, poorly implemented.

Не показано что этот сервис работает не для все стран!!! Для россии его нет например !

Latest version is worse then ever. I want to open a website and it keeps telling me that i need to open it in a container it was opened before even if i check remember this choice. I turned it off. This is not workable anymore ! It used to be such a nice plugin. Now its not ok anymore.

This extension used to be amazing, but out of nowhere it stopped working correctly. Now my containers are no longer sandboxed and when I login on one, I have to log out on the others. This is exactly why I use it, to not need to sign out when switching from one login to another, and it is no longer of any use to me.

ask user want which container to open is not necerrasy.

"要用您指定的容器開啟此網站嗎" 是多餘的動作

The latest version (8.0.7) is even worse than last time I tested this extension: still no wildcards support, horrible performance, and ads for Mozilla VPN: one at install, another one after opening the popup, and yet another one when managing a container...

Causes my computer to use over 1,000% CPU while Firefox is completely idle.

This extension is okay but has at least two major issues:

• It's a massive pain to do things that require third-party sites, for example, if you put Google into its own container, logging into StackExchange sites using OAuth or logging into YouTube become quite the ordeal. 😕 Likewise, you can't log into YouTube unless you reassign Google to "always in" YT's container, then log in, then reassign Google back to "always in" its own container. It's a MASSIVE pain! Similarly, if you put eBay in one container and PayPal in another, you won't be able to make purchases anymore because you can't log into PayPal through eBay. 🤦

• Likewise, there's no way to use wildcards or container-ize subdomains, so you have to add them all manually. For example, you can't put ALL StackExchange sites (*.stackechange.com) in a container together, you have to manually visit each one individually, then do the multiple clicks and mouse-movements to set it to open "always in se container". And then, you have to do it ALL OVER AGAIN for each one's meta subdomain. 🤦 Not only is it a massive pain, but it also defeats the point to containers since SE can track you via all the other sites that aren't in a container, including drive-by one-off SE sites you might find yourself on where you don't even have an account. 🤦🤦🤦

• I temporarily disabled the addon to try to debug an issue with a site, and when I re-enabled it, ALL of its settings were gone, all the containers, all the assignments, everything. Worse, restoring the containers from a backup doesn't help because it already WIPED OUT ALL THE COOKIES! 😠 Apparently this has been a bug for a long time and they STILL haven't fixed it. (I guess they're too busy wasting their time integrating Mozilla VPN. 😒)

• It also doesn't seem to work for this site (addons.mozilla.org), I checked the code to see if they put an exception for it (for some reason 🤨), but it doesn't seem to contain one, it just doesn't work. (Maybe Firefox suspiciously treats this site in a different way at a base level. 🤔)

• The interface is extremely lacking. There is no way to directly edit the settings such as a text-box to enter domains to assign containers. The only way to do so is to actually go to a site and then assign it to a container. This has numerous problems:
◦ It allows a site to track you at least once before you assign it to a container.
◦ It doesn't work if you're offline.
◦ It doesn't work if the site redirects to another domain or even subdomains (eg www.), so it can harvest data and quickly redirect, passing the data and preventing you from assigning the original domain to a container. This addon NEEDS a proper UI.

This extension does not work.
Try the following on firefox. Log into an Amazon account in a container in one tab, then open another container tab and log in to another separate Amazon account. Go back to the first tab and refresh the tab. The result is that the first tab now shows the account info of the second tab Amazon account.
So in effect these multi account containers tabs do not isolate anything at all.

There is a very annoying problem: I selected "Remember my decision for this site", and selected "Open with container", then opened a new tab, and then opened the same site, and the prompt appeared again! I've searched the settings and there is no option to remove this site prompt! Also, even though I've opted not to open the container, it still opens as a "private" container, and I can't find an option to remove this site's settings at all.

annoying 4 preset containers, cannot hide and coming back every time i install the addon again, even with sync enabled. Whats more, sync experience was back.

Does not work comes up blank no adding no subtracting just a bunch of containers without any editing adding or subtracting couldn't paste a screenshot
