The short version

  • Each has a real cost: ClickUp the free plan is capped at 60MB of storage, 5 spaces, 1 form and 3 whiteboards, so the limits are structural rather than just a seat count; 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: ClickUp covers Multiple view types, 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.

ClickUp

  • The free plan is capped at 60MB of storage, 5 spaces, 1 form and 3 whiteboards, so the limits are structural rather than just a seat count
  • Gantt charts, time tracking and goals require Unlimited at $7 per user per month billed yearly
  • Automations are rationed by tier, at 5,000 a month on Business and 250,000 on Enterprise
  • SAML SSO, custom roles and HIPAA compliance are Enterprise only
  • AI is charged separately, at $9 per user per month for Brain and $28 for Everything AI
  • Monthly billing is substantially dearer, at $10 and $19 against the yearly rates

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

ClickUp: How many views does ClickUp support?

ClickUp includes List, Table, Board, Calendar, Gantt, and Inbox views, plus Whiteboards for collaboration and multiple specialized views for different workflows.

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.

ClickUp: What is ClickUp Brain?

ClickUp Brain is the AI feature providing workspace Q&A, task summaries, and AI-powered automation available as an add-on at $9 or $28/user/month depending on usage.

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.

ClickUp: How long does it take to set up ClickUp?

Initial setup typically takes 2-4 weeks depending on team size and complexity needs, which is longer than Monday.com (1-2 days) but necessary for ClickUp's flexibility.

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.

ClickUp: Does ClickUp have built-in time tracking?

Yes, time tracking is included in the first paid plan (Unlimited) at $7/user/month, allowing teams to track project hours without additional tools.

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.
