Ghostery has or has had some controversial analytics called GhostRank that it collects(it may be opt-in I'm not sure). But uBlock Origin is definiently the best content filtering extension I've ever used.

I think it’s opt-in. All the “share data” checkboxes in the “Support Ghostery” panel are unchecked for me.

It's opt-in, and has also been acquired by a company building a privacy-focused browser (I think?).

From what I see, it’s a small German startup that puts emphasis on user privacy. Sounds fine to me.

I personally prefer privacy badger over both. You can't add trackers to Ghostery, and I don't much care about ads that don't track me (I don't watch internet videos, I might not have this opinion if I did), and any particularly annoying ads just get blocked manually in privacy badger.

On mobile, there unfortunately is no such thing (no user scripts on chrome or Firefox, no privacy badger either), so I usually just disable JavaScript or use whatever privacy browser I have installed (currently Firefox Focus).

Privacy Badger is available on Firefox for Android. You might want to take a look at it if you use Android.

Firefox Focus also applies its privacy features to Safari browsing; are there any benefits to actually using Focus as a browser?

I use both. uBlock Origin catches pre-roll ads on YouTube as well as some other things that Ghostery lets through.

I use Disconnect rather than Ghostery in addition to uBlock.
