  • They diverge on capability: Ghostery covers Privacy dashboard, uBlock Origin covers Malware domain blocking.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Ghostery

  • Database of trackers requires regular updates to remain current
  • Some sites break functionality when trackers are aggressively blocked

uBlock Origin

  • CNAME uncloaking of third-party trackers disguised as first-party is only available on Firefox, because the required DNS API does not exist in Chromium
  • HTML filtering of response bodies requires the webRequest.filterResponseData API, which is only available in Firefox
  • On Chromium-based browsers uBO is not reliably ready at browser launch, so tracker and advertisement payloads can reach already-open tabs before filtering starts
  • Pre-fetch blocking is not reliable on Chromium-based browsers because they give websites precedence over user settings
  • The Chromium build does not use the WebAssembly filtering code paths, because the extra manifest permission would create friction publishing to the Chrome Web Store
  • LZ4 storage compression is Firefox only, and on Chromium in incognito mode IndexedDB resets, so uBO launches with out-of-date filter lists
