The short version

  • Each has a real cost: Mozilla Firefox roughly 85 per cent of Mozilla's revenue comes from search default placement deals, overwhelmingly with Google, so the organisation that competes with Chrome depends on Chrome's owner for its funding and any renegotiation lands on Firefox's engineering budget within a quarter.; Wappalyzer cannot detect server-side or hidden technologies without client-side footprints
  • They diverge on capability: Mozilla Firefox covers Gecko engine, Wappalyzer covers Technology detection.
  • 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.

Mozilla Firefox

  • Roughly 85 per cent of Mozilla's revenue comes from search default placement deals, overwhelmingly with Google, so the organisation that competes with Chrome depends on Chrome's owner for its funding and any renegotiation lands on Firefox's engineering budget within a quarter.
  • Desktop market share sits at a few per cent, so commercial sites are tested against Chrome and Safari and a Firefox-only rendering or WebRTC bug is triaged as low priority by the site owner, leaving you with the workaround.
  • On iOS and iPadOS the browser is a WebKit shell required by Apple's rules, so it delivers the interface and Sync but none of the engine, extension or tracking-protection behaviour that make Firefox worth choosing on desktop.
  • Mozilla declines to implement several hardware-facing APIs on principle, including WebUSB, WebSerial, Web Bluetooth and WebHID, so a web application that talks to a device simply does not run and no configuration flag changes that.
  • Enterprise management is limited to policies.json and ADMX templates; there is no first-party equivalent of Chrome Browser Cloud Management, so fleet-wide reporting on versions and extensions requires third-party tooling you have to buy or build.
  • Mozilla repeatedly ships decisions its own user base objects to, such as enabling Privacy Preserving Attribution by default and the 2025 Terms of Use rewrite, and reversals arrive after the news cycle, so deploying it on a privacy argument means owning the communications work each time.

Wappalyzer

  • Cannot detect server-side or hidden technologies without client-side footprints
  • Went closed-source in 2023; self-hosting now difficult without maintaining community forks
  • Data export features locked to Business plan ($450/month) minimum

Answered from the vendors’ own pages

Mozilla Firefox: Does uBlock Origin still work on Firefox?

Yes. Firefox has kept the blocking webRequest API that Chrome removed with Manifest V3, so uBlock Origin runs with its full rule set rather than the cut-down Lite version Chrome requires.

Wappalyzer: Does Wappalyzer have a free version?

Yes. Wappalyzer's browser extension is completely free and provides unlimited technology lookups with no account required. The free tier includes basic website technology detection across all categories.

Source
Mozilla Firefox: Is Firefox on iPhone the same browser?

No. Apple's platform rules require it to use WebKit, so on iOS and iPadOS you get Firefox's interface, Sync and bookmarks on top of Safari's engine. The privacy and extension behaviour are not the same.

Wappalyzer: What are the paid pricing tiers for Wappalyzer?

Wappalyzer's paid plans start at $250/month for Pro (5,000 lookups, 1 user), $450/month for Business (20,000 lookups, 5 users, API access), and $850+/month for Enterprise (200,000+ lookups, 25+ users). Annual billing offers 17% discount.

Source
Mozilla Firefox: How is Mozilla funded, and does that matter?

Mainly by payments for making a search engine the default, with Google as the dominant payer. It matters because it is a single-source dependency on a direct competitor, and it has been the subject of antitrust litigation whose outcome Mozilla does not control.

Wappalyzer: Can Wappalyzer detect all website technologies?

Wappalyzer detects over 1,000 technologies but cannot detect server-side or hidden technologies, backend infrastructure, internal databases, or ERP systems with no client-side footprint.

Source
Mozilla Firefox: Can I manage it across a company fleet?

Yes, through policies.json or Windows Group Policy with the ADMX templates, and the ESR channel gives you a roughly yearly major version instead of four-weekly. There is no first-party cloud management console, so reporting needs other tooling.

Wappalyzer: Can Wappalyzer be self-hosted?

Wappalyzer went closed-source in 2023 when the GitHub repository was taken down. It can be deployed via Docker or npm, but the community-contributed fingerprint database is now part of the commercial product. Open-source forks are available but not officially maintained.

Source
Mozilla Firefox: Will every site work in it?

Most will. The exceptions cluster around sites tested only in Chrome, legacy enterprise applications, and anything using WebUSB, WebSerial, Web Bluetooth or WebHID, which Firefox does not implement at all.

Wappalyzer: What integrations does Wappalyzer offer?

Wappalyzer integrates with CRM systems like Salesforce and HubSpot, and supports lead list exports and API access for business users on paid plans.

Source
Wappalyzer: When does Wappalyzer data export become available?

Data export and lead list generation features are only available on the Business plan ($450/month) and above, not on the Pro tier.
