The short version

  • Each has a real cost: ColorZilla the vendor's own homepage as captured by the Internet Archive on 2 January 2022 describes ColorZilla only as a free browser extension for Firefox and Chrome (eyedropper, color picker, gradient generator) with no paid tier, pricing page, or subscription mentioned anywhere on the site; 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
  • They diverge on capability: ColorZilla covers Color picker, uBlock Origin covers Ad blocking.

Where each one falls short

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

ColorZilla

  • The vendor's own homepage as captured by the Internet Archive on 2 January 2022 describes ColorZilla only as a free browser extension for Firefox and Chrome (eyedropper, color picker, gradient generator) with no paid tier, pricing page, or subscription mentioned anywhere on the site

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  • LZ4 storage compression is Firefox only, and on Chromium in incognito mode IndexedDB resets, so uBO launches with out-of-date filter lists
