The short version

  • Each has a real cost: DeskTime screenshots are excluded from the Pro plan and start at Premium; 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: DeskTime covers Automatic activity tracking, Mozilla Firefox covers Gecko engine.
  • 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.

DeskTime

  • Screenshots are excluded from the Pro plan and start at Premium
  • Integrations and API access require the Premium plan
  • Shift scheduling requires the Premium plan
  • Enterprise is aimed at 200+ users and is priced by quote with no published rate
  • The advertised $6.42 and $9.17 per user rates require annual billing; monthly billing costs more
  • The trial lasts 14 days

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

DeskTime: What are DeskTime's subscription tiers?

DeskTime offers Pro at $6.42/user/month (annual billing) for small teams and startups, Premium at $9.17/user/month (marked Most Popular) for hybrid and growing teams, and Enterprise with custom pricing for 200+ users.

Source
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.

DeskTime: What features differentiate the Premium tier from Pro?

Premium adds screenshots, integrations & API, and shift scheduling compared to Pro's document title tracking and calendar integrations.

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.

DeskTime: How long is the DeskTime free trial?

DeskTime offers a 14-day free trial. No credit card is required to start.

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.

DeskTime: What billing options does DeskTime offer?

DeskTime offers monthly or annual billing. Annual subscriptions include one complimentary month compared to monthly plan pricing. You can pay by credit card or PayPal.

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.

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.
