Works very well, would be nice to extend it from Gmail also to Google Inbox as that's now my preferred mail tool.

Works perfectly , tested with Signals/Sidekick . 1 star less because there is no way to unblock it

It works! Almost every single piece of promotional or corporate email in my Gmail turned out to have tracking embedded. Not that I really care about most, but it seems dishonest that the message would not tell me that they were tracking my response time etc, so now I am PixelBlocking them all. Honesty first, you advertisers you!

I installed this extension, but unfortunately it worked too well without enough options. I want the option to block all incoming tracking requests without blocking my outgoing tracking requests, currently sent via another extension (Streak). I realize this is a bit hypocritical, but that's territory I'm used to as an internet marketer.

A good step in the fight for our online privacy. I didn't even know that they can track that much.
