As of this writing Ghostery is fully incompatible with YouTube. You must disable it or the site will barely function. (YouTube becomes incredibly laggy and videos will take forever to load). I submitted a ticket to the Ghostery support team and they said they fixed the issue, but the problem is not fixed even a little bit.

Been having issues with Youtube being seriously slow over the past week, been examining my PiHole for any issues, but then went through my browser extensions one by one and found that Ghostery was slowing it down to the point where videos wasn't loading thumbnails. Once I'd removed the Ghostery extension, Youtube worked properly again.

Probably triggers youtube's adblock protection. Makes youtube completely unusable while that on. Maybe other web-sites works worse performance wise (its funny to see when website assemble itself visibly like i'm using my old Pentium 4 PC from that era). But you gotta choose privacy or performance in today's reality :/

It works, but also drastically worsens performance while under load.

I'm sure it is usually good, but currently it completely slows down youtube for me, might be due to conflicting add-ons or some new stuff youtube added, but in this state it is, for me, unusable.

I install this extension on every device I have admin access to. It's the first one I install on a fresh Firefox install. I especially recommend it to auto decline cookies.

gotta respect the hustle.

Been using it for so many years now. Love this app. SO glad they have it for Firefox!!

cela fait un long moment que j'utilise Ghostery vraiment c'est très bien ça s’améliore et je ne vois pas utiliser mon navigateur sans .merci bien

Works, shows good, readable statistics, uninvaisive.
Great ad blocker, no random pauses where an ad would be.

Always works, always makes browsing more quiet.
