This used to be one of my favorite add-ons for work in order to run separate instances of one program simultaneously.

Now it's become almost unusable because every time I open a link related to my work, I get that annoying pop-up message "Open this site in your assigned container?" and there is NO WAY to get it to stop. Even if I checkbox "Remember my decision" it will continue to pop up, regardless of if I click yes or no. When I attempt to manage the Container settings to remove or add the site, it's no help at all - it's completely blank and there's nothing I can do.

I wanted to report it to GitHub but it appears this was actually intended as a FEATURE and not a bug. Well, it's a really annoying feature and I wish I could turn it off.

Edit: I would appreciate if the reviewer above me would not imply that I had "done something wrong". The pop-up windows were unprompted and occurred whether or not I had Containers synced to my account, and I had troubleshooted various methods of resolution.

I want to open a web page in different containers but by default I want it to never ask me.
i have the same opinion of James Tuttle,
This extension is awesome, except for the fact that EVERY time you click on a link, open a new tab or type in a website url an error pops up asking "Open this site in your assigned Container?". You are then required to click ok if you want your page to load. The Firefox forum shows several people asking for a solution, with Firefox devs stating there is no solution because "Interrupting the user every time they open a new tab is how the containers plugin is supposed to work." As far as I can see, no one has been able to find a work around yet to make it so that when you right click and "open in new tab", Firefox is actually able to figure out how to open your link in a new tab without popping up that extra prompt.

El complemento es excelente pero el hecho de que pregunte si se quiere abrir la pagina en otro contenedor, que no guarde el enlace en el nuevo contenedor y que no existe una configuración para estas dos opciones hace el complemento sea pésimo.

UPDATED! There needs to be a list of sites. maybe add this to the bookmarks tab with tick boxes on the side on what tab options you would like for them to open with. also have the option to to have full browser account switching like chrome.

Forced, unskippable intro cards.

I will give it one start because the second and the third most important features are still not implemented.

The second one is sorting. When you have many-many containers, let's say 100, it becomes nightmare to maintain order within them, especially when moving to a new PC.

The third thing that is lack is the ability to add domain masks (like *.google.com) instead of all sub-domains one-by-one to a container's list.

It would also be nice to have the setting to open all links not presented in the current container not in the context of this container. For example, when I open a link in a Google, I don't wish this link to be opened in a "Google's" container, it should be no-container tab.

It seems like Mozilla just released the product and completely abandon it right after release, without any plans to add new features, which is very sad. :(

- 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! :-(
