This add-on is promising, but is useless to me without the ability to sync preferences.

Полезное расширение.

Love ur open source thing.

This add-on does exactly what I need it to do. I have three profiles setup (for three different Google account) and use it to open certain websites with the appropriate profile. It is nice being able to have different profiles share the same window.

It would be nice to have different shortcut keys for opening new tabs in different profiles.

yooooooo

I love the idea, it works really well to separate environments, like separate google and facebook, or have two separate google accounts.
It lacks an important feature: not sharing history between containers.

ótimo para várias finalidades: separar uma aba 'comum' de uma pessoal* e separar dados de sites bisbilhoteiros são as mais úteis... *útil quando sua mãe pede pra abrir nova busca e você não quer um monte de bolos no seu histórico...

makes my work way more easier

Love this idea. Hopeful that other means of fingerprinting can similarly be obscured (IOs Safari's new tools seem to show promise), but this is a good tool--thanks!

Excelente! Es lo que estaba necesitando

Great extension.

topkek really helps with signing in into different accounts, although you can only be signed in into one account at a time per website. still wish that the profile feature in firefox were more like chrome's

Very safety

With this I can still use accounts with privacy-unfriendly companies when I want to, without being logged into them all of the time, and without juggling private sessions. It also lets me keep around multiple sets of settings for any given site, which means I can migrate away from old accounts at my own pace.
