For some reason, this extension breaks Firefox Sync. When I enable this extension and try to turn on the cloud sync functionality of the containers, Sync no longer works (says "Syncing" endlessly). If I click "Manage Account" in the Profile menu, it opens to an error. I can't remember what it says because I've had to create multiple Firefox profiles to fix this and gave up.

NOT enjoying at ALL. All my customized containers disappeared, only 4 default containers. There is NO "Manage Containers" option anymore. So I cannot even recreate them. What the sam hill is going on ?

not possible to open. Collecting yes but not for use.

Is not proxy or any vpn.

poor performance with 2-factor authentication such as Duo Security, and even worse performance if you need to access the same website from multiple accounts like Google with work account and personal account. It picks the wrong container automatically when I'm trying to use a different account. Bricks several website login pathways with my work accounts.

All the positive reviews claiming this extension works are either bots or AI. The fact is it doesn't work especially on Meta (Facebook pages) and neither does the other Firefox container called Facebook. Besides, it's incredibly difficult to verify it actually works and in my case I know it doesn't because I use a good VPN and Meta still knows I am not in the country I claim (and no, I am not leaking DNS either). I mean, at first the VPN does it's job but then when I click on a link in FB I am redirected to the site it knows my true location then and starts giving me ads for the country I am physically in. I tried different VPNs and ran extensive tests to verify these container extensions do not work at all.

- constantly asks to confirm
- can we pls. make it so that i can set a bookmark for amazon to open in one container, then make a bookmark to amazon and specify to open in another? why can we not say directly in the bookmark which container to use (without confirmations and delays)

Не работает..

я использую для кабинета рекламы. У меня 10 аккаунтов. Но он постоянно предлагает использовать первый для этого сайта, не удобно

Youtube videos don't load when this is enabled.

Clunky and awkward and not useful for real life situations. If I want to search on Google at both home and work I can't. Switching from one container to another requires manually clicking small buttons - annoying! The UI is tiny and small, and puts too high of a priority on displaying adverts.

Beware all login info and site data in containers will be cleared whenever FF decides to randomly update/refresh extensions

It's pretty funny that you can't set saved passwords to always open in a container.

This is technically useless. I have the joice between the plague or cholera.

Lemme explain why.
If i want every website seperated i have to setup everything manually.
i dont want an addon becomes part of my bucketlist.

This extension keeps restoring deleted containers, which is very annoying if you've previously used Temporary Containers.

There's no way to use this extension. It doesn't install a toolbar icon, nor is there one available anywhere. Also no new right click menu items show up.

When using the "limited to designated sites" setting you have to wait for every tab to time out before you can add it to the container.
Also the possibility to use wildcards in the URLs would be a minimum requirement to make it usable for a developer.

Add-on is in Russian and it is NOT the language of my OS nor FF. I don't see the option to change the language. It doesn't spark confidence in this add-on in current geopolitical situation.

Terribad sync, messed up everything
