The short version

  • Each has a real cost: Corteza planet Crust is a small company of roughly a dozen or so people, so the entire commercial support capability behind Corteza is thin and a large deployment can outgrow the vendors ability to respond.; 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.
  • They diverge on capability: Corteza covers Corteza Low Code, Mozilla Firefox covers Gecko engine.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Corteza

  • A European public body that needs a case management system on servers inside its own jurisdiction with an auditable licence and no per-seat vendor feenot Mozilla Firefox
  • An NGO replacing a Salesforce donation that has run out, needing to keep the data model but remove the recurring costnot Mozilla Firefox
  • An integrator building a regulated vertical application it intends to resell, requiring a permissive licence it can ship commerciallynot Mozilla Firefox
  • A mid-size European company that wants one platform for internal applications and a sales pipeline without paying per seat as headcount growsnot Mozilla Firefox

Mozilla Firefox

  • Web development where you need to test against a non-Chromium engine before shipping, because Chromium-only testing hides real bugsnot Corteza
  • Users who require a full-strength content blocker, which Chrome's Manifest V3 no longer permitsnot Corteza
  • Managed fleets that need a browser on a slow release cadence with Group Policy control, using the ESR channelnot Corteza
  • Handling several accounts on the same service at once through container tabs, without separate profiles or private windowsnot Corteza

Where each one falls short

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

Corteza

  • Planet Crust is a small company of roughly a dozen or so people, so the entire commercial support capability behind Corteza is thin and a large deployment can outgrow the vendors ability to respond.
  • No pricing is published for Planet Crusts support, hosting or implementation services, so the true running cost of a supported deployment cannot be estimated without a sales conversation.
  • The connector ecosystem is small compared with commercial low-code platforms, so integrations with common SaaS tools usually mean writing against the REST API rather than installing something.
  • Hiring is hard: almost nobody has Corteza on a CV, so you are training internal developers on a niche platform and you cannot easily replace them.
  • The bundled CRM is a starting point rather than a mature product, and teams that expect Salesforce-equivalent sales functionality out of the box will spend months building the gap themselves.

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.

Answered from the vendors’ own pages

Corteza: Is Corteza the same thing as Crust?

Yes. The project was branded Crust and renamed Corteza in 2019 when Crust Technology donated it to the Commons Conservancy.

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.

Corteza: Who owns the code?

The Commons Conservancy, a Dutch foundation. Planet Crust in Cork is the primary developer and sells commercial services around it.

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.

Corteza: Is there a paid enterprise edition?

No. Corteza is Apache 2.0 with no feature gating. Planet Crust sells support, hosting and development instead of a restricted edition.

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.

Corteza: Can it genuinely replace Salesforce?

For case management and a straightforward sales pipeline on a self-hosted footprint, yes. For a large sales organisation relying on AppExchange products and a mature ecosystem, no.

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.

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.
