The best Firefox feature in a long time. Well done Mozilla!

Honestly one of the coolest implementations now giving you a weapon against the abomination that tech companies have turned capitalism into lately. Does Amazon tell Facebook what to post on your feed? Ever wonder how 80% of websites you visit can somehow acquire instant access to post-on/edit your perpetually logged-in Facebook or Google account?! Do you ever feel as though all of your private Google searches are now giving everyone this detailed summary of all your interests? Makes me sick.

Stop.
Stop making it so easy for them! You shouldn't be offering up all this constantly cross-referenced personal information everyday:
Just container all the sites separately! Facebook, Amazon, your TV shows, your email. You'll quickly feel the giant relief of these multi-billion dollar companies struggling to take advantage of your cumulative browsing habits. Instantly, just like that, they've just lost their ability to gang-up on poor you.

Do it. You should confuse the hell out of em. Feel the power, you strong independent internet user, you.
