Recently started using the add-on. Looking forward to seeing it in Firefox for Android someday.

One of the best and most helpful add-ons I've ever used.

very good

Amazing Firefox plugin!
Should be integrated into Firefox by default(but as default being disabled), but either it's very nice! Recommend it to everyone & the best feature of it is: "Auto open this-website in a set-container", but anyway all of it's functionality is really nice and simple & I love it!
Reminds me of 'Docker's Containers' haha, but they're very different although their meaning is kind of similar :)

Love the ideal of "containing" entities who are trying to expand the perpetuate the legality and, perhaps worse, the public acceptability, of hoovering up and analyzing every single thing that I do on the Internet. If you think for a nanosecond that they wouldn't harvest every single bit of data about us that they can legally harvest, clear your head. And harvest means use. And use is just one fairly short fall to horrible abuse that will be very hard to recover from, if that's even possible. So contain them? Of course, please expand on this capability in the name of the public.
