If I remove a page to open in certain container, after syncing it will come back and page will still open in that container. But I deleted page from the container.

No way to see tabs in a single container. It helps to keep multiple accounts, but without being able to segregate it's even more difficult to handle tabs.

Не работает.

Yet another icon taking up space so I have to reorient simply to enter a url in the urlbar. Just keep icons with the other icons in the toolbar NOT the urlbar.

Unable to uninstall

Spent hours setting my work containers up. I go back to my personal PC and sync. It doesn't sync. Go back to work and see everything is messed up.

Wenn ich einen neuen Container öffne sind alle Cookies, auch die aus anderen geöffneten Containern enthalten. Ich habe das jetzt mehrfach geteset. Somit ist diese Erweiterung für mich unbrauchbar.

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.

Inconsistent behavior between Firefox versions with no options to adjust the differences in behaviors. Terrible UI (sadly something Firefox excels in these days) both clunky and ripe with nags about Mozilla services no one asked about. Worse is removing it doesn't stop the obnoxious behaviors has you have to manually delete all the container names/categories before removing it to have it actually stop "working."

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. :(
