Ask HN: What privacy focused plugins do you use?

In the wake of a lot of the concerns for online privacy and being tracked online it's become more and more apparent that plugins are necessary to sort of 'harden' your browser from leaking too much information (which can be used to track and identify you online) by restricting what the browser can do.

What are some of your favorite plugins?

Some I've found recently / have been using for Firefox include:

Decentraleyes, CanvasBlocker, AdBlocker Ultimate (kinda hard to figure out which AdBlocker is the "best" / trustworthy), Firefox Containers, Facebook Container, Don't Touch My Tabs, and Disconnect.

Notice: I know this doesn't stop them from fully tracking us, but it at least helps, and in some cases improves browsing experience on the web tenfold.
