La aplicación es muy fácil de usar. Puedes personalizar cada contenedor y cumple perfectamente con su objetivo. Es genial

Almost perfect. I'm pretty sure this add-on is to blame for my tabs opening external links inside themselves. the "_blank" seems to be ignored by this. Especially frustrating on pinned tabs (like Hangouts/Gmail)

Helped me a lot to organizing my favorite tabs

Very useful addon. I suggest would be cool to also have domain rules, like *domain.com

indispensable

buenisimo

Very useful addon, but would be cool to also have domain rules, like *.google.com, like in some other extensions. Also, in my case, addon doesn't react on addons.mozilla.org and always opens it in default container, despite preferences, so as firefox profile (if I click on a firefox button on top right) but it's not that essential and maybe is a firefox prerogative. Anyway, thanks!

amazing feature this was what we needed! great job firefox!

This doesn't seem to work for Facebook

A must have for anyone who values privacy and understands how the modern web takes advantage of tracking.
