good and could easily be great.
1) option for coloured tab instead of a line to denote the container
2) grouping containers into windows would be a nice option to unclutter a single window and gives purpose to alt-tab switching between container windows

i am quite secure that this addon is making that firefox 114, and the current 115 version(when i am writing down this) is quitting to time to time with not reason. Please you revise or update it

Bardzo mi się podoba ten dodatek. Jedyne, czego mi brakuje, to polskich komunikatów. Jest czytelny, konfigurowalny, prosty. Polecam!

Hey how do i back up my containers (with the respective data associated to those containers /cookies, logins and such)?
You know... in case things ever crash or i want to reinstall the browser without losing all the login info associated with the container.
if that's not a feature yet, could you PLEASE make that a feature? :3
if it's a feature please tell me how.

The least painful way of getting separate cookies/logins for the same sites and also being able to separate activity as a bonus. Does what you need for the most part.

The reason for it not being 5 stars is because it is lacking in features I think, the most important things for me would be fresh cookies or separated cookies by default or the option to start fresh for each container, it seems that when I create a container I am already logged in so I need to sign out of all of the ones I want to use on that site. The second thing would be to have a fast way to open many containers such as ctrl+click on each of them which would ideally keep the menu up while doing it if possible, otherwise another quick way to select them would do.

I've used this add-on for several years quite loyally now. It's THE primary reason I use Mozilla browser for work stuff. But now the Containers tabs won't load my pages in new windows for AWS accounts. :( I've done all I can think of to fix the issue on my own and leaving a review in hopes to get this fixed. This app makes my job so much easier and I'd like to keep using it.

Using this container has made my browsing more private. There is a bug that if I add a new container and re-arrange it, the shortcuts don't change according to the order of containers, the new container always picks up the higher number.

Allows you to maintain separate logins or even separate sessions for the same login. There is one missing piece of functionality however, which is that although you can specify sites to always open in a container, you cannot specify this for individual URLs (e.g. bookmarks).

The only reason I'm giving 4 stars instead of 5 is because I'd like there to be a way to manage the site lists for my containers manually (i.e. by typing a site address into a text box & hitting "add to list") as opposed to having to navigate to that website & then use the "Always Open This Site in..." button to get it to show up in the list.

Other than that nitpick, I love this! I like being able to have at least some control over the information that trackers from any given site get, & it's been good for organizing tabs as well!

very good, but is there an option to allow "back button" to work when containers switch, i.e. when I search thru google and the results say reddit which will open on different container, now since its different container back buttton will not work

Would be better if you could make your own containers or rename the available ones

Es ist eine dieser coolen Erweiterungen, die man erst mal finden und verstehen muss.
Wenn man sie aber eine Weile nutzt merkt man, dass Ordnung entsteht. Ich habe nun mal eine Welt, in der man mal abhängt, mal arbeitet etc. Und mit dem Container kann ich die vielen Tabs visuell trennen, den richtigen VPN-Standort zuweisen etc.
Gern würde ich die Tabs besser gruppieren können, so wie im Chrome. Aber vielleicht kommt das ja noch. Aber deshalb eben nicht alle Sterne.
P.S.
Aktuell verwende ich deshalb zum Gruppieren die 'Tree Style Tab'-Erweiterung.
P.P.S. Der Fairnis halber muss ich noch hinzufügen, dass ich eben herausgefunden habe, wie ich die Tabs nach Containern sortieren kann. Und das ist ja dann schon fast wie Gruppieren:-)
P.P.P.S. In übernächster Bewertung meint User=17689965 man könne die Container nicht sortieren. Vermutlich meint er, sie sind nicht automatisch sortierbar. Aber ich habe 8 Container und davon 4 aktive. Und die lassen sich sehr wohl sortieren. Und zwar manuell und dauerhaft.

(Double edit: thought I was writing a redundant review but it turns out listing ones reviews in ones profile it doesn't tell you WHAT the review is of...HOWEVER, getting to "CONTAINERS IN FIREFOX..."

TL; DR version:
Like:
Moderately highly recommend as a "why not should help not hurt" additional layer of privacy defense, and has features that become semi-automated so it can be integrated into your workflow without much effort.

Would like if:
I'd like a little more customization (UI) and as a non-tech person (I only know a couple things) I would like to underrstand more of the "UX" lol, but while no one is perfect, this extension (literally) of a "non-profit seems like a no brainer though unclear how MUCH it helps it's easy to use.

The TL;DR "more"
Seems to do what it says it will do (in the background) well, and/or perhaps it's simply extra layer of defense I think at minimum? One thing I don't like is not being able to change the primary categories...you can add additional containers naming them anything you want, and I HAVE done that for a couple. They limit the number of symbols and colors you can use for each container which is only slightly annoying ;-) I LOVE how I set it to "open new tabs in a container" and it brings it up and you choose so don't forget, and how it automatically opens different web sites in the asssigned container (it asks you "always open in this container?" which is also a nice workflow/don't have to remember thing. These days things are so complicated that between the native browser protections, additional settings, add ons like this, etc, it can be very difficult to figure out if something doesn't work on a website where the problem is. That seems to be a rare problem though and I've worked around it and don't know that ANY were from this extension. The click symbol to change to a container is also eay to use/find. This seemed like a "no brainer" especially with the objects-in-libraries-associated-with-appearance-of-person-company company who along with those that had one strange rule and couldn't keep it strangely which has many services including finding things on the web, the container thingee is relatively simple and seems to work well not that I can tell what's going on under the hood but file under "probalby helps; doesn't seem to hurt or if does hurt not much at all!"
