The short version

  • Each has a real cost: Linear no task-level Gantt chart; Timeline view is available for projects only, not individual issues; 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: Linear covers Fast, real-time sync, Mozilla Firefox covers Gecko engine.
  • Prices and features above were last checked on 30 August 2026.

Mozilla Firefox

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

Where each one falls short

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

Linear

  • No task-level Gantt chart; Timeline view is available for projects only, not individual issues
  • No native time-tracking or hour-logging feature
  • No native Linux desktop app; official FAQ states it 'may come in the future but it's not on the roadmap for now'
  • Free tier capped at 250 issues and 2 teams

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

Linear: How much does Linear cost?

Linear has a free tier supporting 2 teams and 250 issues. Paid plans start at $10 per user per month for Basic and $16 per user per month for Business. Annual billing is required for paid tiers.

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.

Linear: What are the file upload limits on Linear?

The free tier is restricted to 10MB file uploads per team. Paid plans offer unlimited file uploads.

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.

Linear: Does Linear offer an Enterprise plan?

Yes, Linear offers an Enterprise tier with custom pricing, annual billing required, SAML and SCIM support, granular admin controls, and priority support.

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.

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.
