Honestly I found Ghostery useless and ultimately uninstalled it. I am not paranoid enough to want to completely deprive every site of statistics, so I had opt-in by default, and it's difficult to block the especially nefarious packages because they're all lumped together with typical counters/stats scripts.

I think NoScript does an adequate job preventing most undesired analyzers, as they will often be on a separate domain that needs temporary activation. Ghostery was just annoying because it'd always be blaring that there were trackers tracking me, but include mostly things that I don't really mind, basically all counters. In fact, I usually want counters to register my UA/OS, so that their recorded Linux marketshare increases.

Would be nice if we could install Ghostery as a private-browsing-only extension and turn its default to block everything, but barring that, I don't think it's valuable unless you make it block everything all the time.

You know, sites have log files for basic stats... Tracking is completely another league. I feel no guilty using Ghostery fully blocking everything by default (and I'm not so paranoid).

The problem is when you use http cache, it screws your basic stats.

Ghostery is fantastic. It takes a little while to get setup and maintain as you'll want to disable everything by default then reenable services when things don't work. But it's well worth the effort.

I use the Ghostery add-on for Firefox, but if you enable "GhostRank" then the add-on will send every URL you visit to Evidon. This is purportedly for "tracking the trackers", but it does give one pause.

I use this in conjunction with an ad blocker and a NoScripts-like extension.

I always wonder how effective this combination is :/

"Enough for what? is the question. I hope it is enough to disrupt the FB and Google from from getting a total view of my activity but I don't think its enough to stop all monitoring and tracking.

My main browser is Firefox with NoScript installed and I've been known to back away from sites that won't work without a number of different domains being authorised. Flash isn't installed at all. I use Chrome with Ghostery for Linked In/Facebook and any Google logins plus anything that needs Flash (as I trust Google to keep that up to date even though I don't trust them not to track me).

I never log in to Linked In/Facebook/Google on my phone or tablet although I don't have much other protection from tracking there.
