The short version

  • Each has a real cost: ClassDojo the AI homework helper, the 2,000 plus digital book library, detailed progress reports, memory albums and calendar sync are all restricted to the paid ClassDojo Plus subscription; 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: ClassDojo covers Behavior tracking, 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.

ClassDojo

  • The AI homework helper, the 2,000 plus digital book library, detailed progress reports, memory albums and calendar sync are all restricted to the paid ClassDojo Plus subscription
  • ClassDojo Plus is sold to families rather than to schools, so parents pay for the premium tier
  • The Plus page publishes no monthly or yearly price, only a 7 day free trial
  • No pricing is published for the school leader or district offerings

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  • LZ4 storage compression is Firefox only, and on Chromium in incognito mode IndexedDB resets, so uBO launches with out-of-date filter lists
