Where each one falls short

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

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  • LZ4 storage compression is Firefox only, and on Chromium in incognito mode IndexedDB resets, so uBO launches with out-of-date filter lists

Vue.js Devtools

  • Primarily a developer debugging tool, not intended for production use
  • Limited to browser extension format for most users; requires Vite plugin or standalone app for alternative use
