Apparently a fork of uBlock Origin, TunnelBear Blocker is now available for Firefox. It adds protection from Email Tracking, Ultrasonic Tracking, Fingerprinting and blocks Adobe Flash Player. https://www.tunnelbear.com/apps/blocker https://www.tunnelbear.com/blocker/info https://chrome.google.com/webstore/detail/tunnelbear-blocker/bebdhgdigjiiamnkcenegafmfjoghafk https://addons.mozilla.org/en-GB/firefox/addon/tunnelbear-blocker-firefox/
I've checked it out in Opera, it's a simple version of Ghostery. Not bad, but it failed to block certain ads, strangely enough.
But it's based on uBO. https://chrome.google.com/webstore/detail/tunnelbear-blocker/bebdhgdigjiiamnkcenegafmfjoghafk Scroll down and click "Read more".
Yes I read about it, but what I meant is that it doesn't have all of the configurations options of uBlock and Ghostery.
