This benchmark is to measure privacy exposure, by counting the number of **distinct 3rd-party domains** which
|
||||
have been hit by net requests during the benchmark. The lower the number of distinct 3rd-party domains hit, the better.

Measuring directly the number of distinct 3rd-party domains which were hit is a much better and relevant measurement for comparison of privacy protection efficiency in my opinion.
|
||||
|

|

|

|

Caveat: "3rd-party" is defined as a domain which doesn't match the domain of the web page. For sure many
|
||||
domains reported as "3rd-party" actually belong to the same entity which owns the page domain (for example, `yimg.com` is owned by `yahoo.com`). There is no way for the benchmark code to know this, unless using a comprehensive database of who owns which domain -- that is beyond my means. Still, the benchmark is useful if comparing blockers among themselves, or against when no blocker is used.
|
||||
|
||||
Results -- figures are "3rd party / all". Ordered from least 3rd-party hits to most 3rd-party hits. Privacy-wise, lower numbers are better.

Adguard: it sends `GET` requests in the form `https://sb.adtidy.org/safebrowsing-lookup-domain.html?domain={page hostname}` for the first time a URL is visited. This may be related to its _"Phishing and malware protection"_ setting. Just a guess.

Ultimately, if you **really** want to increase significantly control over your privacy, [HTTP Switchboard](https://github.com/gorhill/httpswitchboard#http-switchboard-for-chromium) is the way to go.
|
||||
If web page breakage annoys you, just start using HTTP Switchboard in [allow-all/block-exceptionally mode](https://github.com/gorhill/httpswitchboard/wiki/How-to-use-HTTP-Switchboard:-Two-opposing-views#the-allow-allblock-exceptionally-approach),
|
||||
and blacklist your way up from this starting point. Unlike µBlock and others here, HTTP Switchboard does not
|
||||
have unseen exception filters which often defeat good blocking filters. For example, [**this**](https://github.com/gorhill/httpswitchboard/wiki/About-these-%22%E2%80%98virtually-impossible%E2%80%99-to-block%22-fingerprinting-tools#kind-of-low-breakage) is the way to foil many fingerprinting tricks, canvas fingerprinting included, without preventing javascript execution.

### Methodology
|
||||
|
||||
All blockers were configured in such a way as to compare apples-vs-apples:
|
||||
|
||||
- **µBlock:** out-of-the-box settings -- no change.
|
||||
- **Adblock Plus:** out-of-the-box settings + _"EasyPrivacy"_, _"Malware Domains"_ checked. _"Acceptable ads"_ unchecked. _"Update now"_ clicked.
|
||||
- **Ghostery:** out-of-the-box settings + _"Advertising"_, _"Analytics"_, _"Beacons"_, _"Privacy"_ checked. _"Widgets"_ not checked. _"GhostRank"_ not checked. _"Update now"_ clicked (and ensured whatever new filters were used).
|
||||
- **Adguard:** out-of-the-box settings + _"Spyware and tracking"_, _"Phishing and malware protection"_ checked. _"Social media"_ not checked. _"Acceptable ads"_ unchecked. _"Check for filter updates"_ clicked.
|
||||
- **Ghostery:** Select all trackers. _"GhostRank"_ not checked. _"Update now"_ clicked (and ensured whatever new filters were used).
|
||||
- **µBlock:** out-of-the-box settings + local mirroring enabled (through _"Experimental features"_).
|
||||
- **Adblock Plus:** _"EasyList"_ + _"EasyPrivacy"_, _"Fanboy's Social Block List"_, _"Malware Domains"_ checked. _"Acceptable ads"_ unchecked. _"Update now"_ clicked.
|
||||
- **Disconnect:** out-of-the-box settings -- no change.
|
||||
- **Privacy Badger:** out-of-the-box settings -- no change. The extension was "primed" by visiting all the URLs in the benchmark three times before running the real benchmark.
