The short version

  • Each has a real cost: Google Chrome manifest V3 replaced blocking webRequest with declarativeNetRequest, which imposes hard caps on the number of filtering rules an extension can apply, so uBlock Origin does not run on Chrome and its Lite version blocks measurably less; if content blocking matters to your users, this is not a setting you can change.; 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: Google Chrome covers Chrome Browser Cloud Management, uBlock Origin covers Ad blocking.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Google Chrome

  • Manifest V3 replaced blocking webRequest with declarativeNetRequest, which imposes hard caps on the number of filtering rules an extension can apply, so uBlock Origin does not run on Chrome and its Lite version blocks measurably less; if content blocking matters to your users, this is not a setting you can change.
  • The browser is the entry point to Google's account, search and advertising business, and the defaults, prompts and sign-in flows all pull towards a Google account; running it fully detached is possible but requires policy and ongoing attention as new prompts are added.
  • Site isolation runs a process per site, which is correct security design and expensive in memory; on machines with 8 GB and users who keep dozens of tabs open it produces genuine slowdowns and support tickets that no configuration removes.
  • The four-week release cadence means a new major version roughly every month, and even Extended Stable delivers one every eight weeks, so any environment that formally certifies browser versions is permanently behind or permanently re-certifying.
  • Because it ships features first and holds the majority of the market, a team that tests only in Chrome builds against Chrome-specific behaviour and finds out about Safari and Firefox breakage from users rather than from CI.
  • Google has reversed direction on Privacy Sandbox repeatedly, announcing third-party cookie deprecation, delaying it several times and then abandoning it in 2025 before retiring several of the replacement APIs, so any advertising or measurement plan built on Chrome's stated roadmap has had to be rebuilt more than once.

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

Answered from the vendors’ own pages

Google Chrome: Why does uBlock Origin no longer work?

Chrome's Manifest V3 removed the blocking webRequest API that it depends on and replaced it with declarativeNetRequest, which limits how many rules an extension may register. uBlock Origin Lite works within those limits and blocks less. Firefox retains the original API.

uBlock Origin: How much does uBlock Origin cost?

uBlock Origin is completely free and open-source software with no licensing fees, subscriptions, or commercial restrictions.

Source
Google Chrome: Is Chrome the same as Chromium?

No. Chrome is Chromium plus Google's proprietary additions: certain media codecs, Google account sync, Safe Browsing integration and usage reporting. Chromium builds omit those, which is why some sites' video playback and sign-in behaviour differ.

uBlock Origin: Is uBlock Origin open source?

Yes, uBlock Origin is distributed under the GPL-3.0 License with source code publicly available on GitHub. The project encourages community review and contribution.

Source
Google Chrome: What does enterprise management cost?

Nothing. Chrome Browser Cloud Management, the administrative policy templates and Extended Stable are all free. This is unusual and is a genuine reason organisations standardise on it.

uBlock Origin: Does uBlock Origin accept donations?

No, uBlock Origin explicitly does not accept donations. The project instead encourages users to support the developers maintaining the filter lists that power the extension.

Source
Google Chrome: How often does it update?

A major version every four weeks on the stable channel, with security updates in between, and every eight weeks on the Extended Stable channel intended for managed fleets.

Google Chrome: Is Chrome on iPhone actually Chrome?

No. Apple's platform rules mean it runs on WebKit, so on iOS you get Chrome's interface, sync and account integration on top of Safari's engine, not Blink.
