Instead of multiple Firefox instances for different related sessions (home, work, shop, ...) you can have all sessions in one , nicely separated in tabs by the color of your choosing.

Ideal per dificultar l'extracció d'informació entre comptes i pestanyes. Perque no puguin saber per quines xarxes socials et mous, o a quines botigues compres. Perque tingueu per segur, que l'objectiu últim d'aquesta recopilació de dades, majoritariament no és per afavorir-vos, si no per cercar noves formes de mantenir-vos conectats

Instead of multiple Firefox instances (by using --profileManager switch) for different related sessions (home, work, shop, ...) you can have all sessions in one instance/window, nicely separated in tabs by the color of your choosing. Been using it for years without any hassle and/or glitches or crashes. IMHO, it should be built directly into a Firefox. Excellent!

Excellent! No more different Firefox profiles, just containers for work and personal stuff. Possibility to have a few private profiles. Easy moving tabs between containers. I wish now every extension could have possibility to have settings per different container. Great to use with Sidebery add-on.

Its a life Saving extension and the only reason why I moved back to firefox.
two things are missing which i would like to add to this.

1st there should be an option to open a url in multiple container simultaneously.
2nd the sorting or change in order of container does not get applied to context menu from where i choose reopen this tab in other container, the custom order does not shows up there

Great feature, should be standard in Firefox! Keep up the great Privacy and Security focused add-on's Mozilla! Be sure to pair this with the Facebook container add-on for best effect.
-A very happy Firefox user

FACEBOOK

very useful to keep goolge account in a container and use google search in another container

This is a great app and to make your experience even better, try using it with the Containers Helper add-on to manage your tabs more easily!

Works really well, I have yet to have any issues with it. I like the organization of it. Sometimes when I am doing research I have more tabs up than what should be legally allowed and the color-coding of this extension helps me keep things organized.
