The short version

  • Only Mozilla Firefox has a free tier, so it costs nothing to try first.
  • Each has a real cost: Memtime no free tier. There is a 14 day trial and after that the cheapest route is €10 a user a month on a two-year commitment, or €15 quarterly.; 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: Memtime covers Automatic activity timeline, Mozilla Firefox covers Gecko engine.
  • Prices and features above were last checked on 24 September 2026.

Where each one falls short

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

Memtime

  • No free tier. There is a 14 day trial and after that the cheapest route is €10 a user a month on a two-year commitment, or €15 quarterly.
  • The integrations most buyers arrive for are on Connect, not Basic, so the entry tier is a local tracker with no link to the project software you already run.
  • Desktop only. There is no mobile app, so work done away from the computer has to be entered by hand.
  • Local-only storage is the product's point and also its limit: there is no central view for a manager, and a lost or wiped machine takes its timeline with it.
  • Tracking is at five or six minute granularity rather than to the second, which is right for reconstructing a day and wrong for anyone billing in one-minute units.

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

Memtime: Does Memtime send my activity data to a server?

No. Activity is stored locally on the device that recorded it and never reaches a server, which is the basis of the product's "built for privacy" positioning and why no manager console exists.

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.

Memtime: What does Memtime cost?

Per user per month, falling with commitment: Basic is €15 quarterly, €12 annual or €10 on two years. Connect is €22, €18 or €15. Premium is €30, €25 or €20. Enterprise is custom from 50 seats. Every tier has a 14 day trial with no card required.

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.

Memtime: Which plan includes the integrations?

Connect and above. Basic covers automatic tracking, timesheets, calendars and reporting, but the 100+ project software integrations and the sync with them start at Connect.

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.

Memtime: How does the automatic tracking work?

It records the program and document in your foreground window at five or six minute granularity and builds a timeline from that. There is no timer to start, so nothing is lost to forgetting.

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.

Memtime: Which platforms does it run on?

Windows, macOS and Linux desktops. There is no mobile application.

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.

Memtime: Who makes Memtime?

Memtime GmbH, a German company founded in 2016.
