The short version

  • Only Mozilla Firefox has a free tier, so it costs nothing to try first.
  • 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.; NordVPN a server in a Finnish datacentre was accessed in March 2018 through a remote management interface left exposed by the hosting provider, and NordVPN did not disclose it until October 2019, so a buyer relying on the company's transparency is relying on a track record that includes a nineteen-month delay.
  • They diverge on capability: Mozilla Firefox covers Gecko engine, NordVPN covers NordLynx.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

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

Mozilla Firefox

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

NordVPN

  • A buyer choosing on evidence rather than claims, who wants a no-logs policy that has been audited more than once by a named firmnot Mozilla Firefox
  • Households and individuals wanting one subscription across ten devices including a smart TVnot Mozilla Firefox
  • Travellers and remote workers on hotel and airport networks who need obfuscation where plain VPN protocols are blockednot Mozilla Firefox
  • Small teams needing basic remote access to a shared resource, via the NordLayer business product rather than the consumer appnot Mozilla Firefox

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.

NordVPN

  • A server in a Finnish datacentre was accessed in March 2018 through a remote management interface left exposed by the hosting provider, and NordVPN did not disclose it until October 2019, so a buyer relying on the company's transparency is relying on a track record that includes a nineteen-month delay.
  • Pricing depends on a long initial term and reverts to the standard rate at renewal, so the monthly figure that justified the purchase is not what the subscriber pays in the third year, and the cheapest way to stay is usually to cancel and re-subscribe.
  • Panamanian registration is selected for the absence of a data retention law, but it also means a subscriber with a dispute has little practical recourse, and the protection rests on a corporate structure the customer cannot inspect or enforce against.
  • NordLynx is unavailable for manual and router configurations, so the one device that could cover an entire home network falls back to OpenVPN or IKEv2 with the associated throughput loss, and obfuscated servers likewise only run over OpenVPN.
  • Features such as Threat Protection are implemented in the client rather than in the network, so any device using a manual configuration, a router or an unsupported platform receives a bare tunnel without the protections the subscription is sold on.

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.

NordVPN: What jurisdiction is NordVPN under?

The VPN service company is registered in Panama, which has no mandatory data retention law for these services. The wider Nord Security group operates from Lithuania.

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.

NordVPN: Has the no-logs claim actually been audited?

Yes, more than once. PwC Switzerland examined it in 2018 and 2020 and Deloitte in later engagements. Each is a point-in-time assurance report over stated policy and server configuration, not ongoing monitoring.

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.

NordVPN: What happened in the 2018 breach?

An attacker reached one rented server in Finland via an insecure remote management tool left in place by the datacentre provider, and obtained a TLS key that had expired. NordVPN disclosed it in October 2019, nineteen months later, and afterwards moved the estate to RAM-only servers.

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.

NordVPN: How many devices does one subscription cover?

Ten simultaneous connections. A router configured with the service counts as one connection regardless of how many devices sit behind it.

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.

NordVPN: Does it work on restrictive networks?

There are obfuscated servers intended for networks that block VPN protocols, but they run over OpenVPN only and no provider can guarantee access in a country that actively filters. Treat it as best effort.
