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.; Sketch macOS-only for editing, blocking Windows and Linux users from accessing design features
  • They diverge on capability: Mozilla Firefox covers Gecko engine, Sketch covers Vector editing.
  • 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.

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.

Sketch

  • macOS-only for editing, blocking Windows and Linux users from accessing design features
  • Real-time collaboration feels less seamless than Figma with occasional sync delays
  • Limited built-in image editing capabilities, requiring external software for bitmap work
  • Subscription required for cloud features and collaboration, losing access if subscription lapses

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.

Sketch: Is Sketch available for Windows or Linux?

No. Sketch is macOS-only for the design and prototyping features. Web and mobile apps provide viewing and collaboration, but editing requires macOS 14.0 or later.

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.

Sketch: Does Sketch offer a free trial?

Yes. Sketch provides a 30-day free trial with no credit card required. You can also purchase a one-time Mac-only license for $120 per seat instead of subscribing.

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.

Sketch: What collaboration features does Sketch include?

Sketch supports real-time collaboration, unlimited document sharing, unlimited viewers, and version history on all paid subscription plans (Standard $12/month, Professional $24/month, Enterprise $44/month).

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.

Sketch: Can I use Sketch offline?

Yes. The one-time Mac-only license ($120) allows you to use Sketch offline and save files locally, but it excludes cloud collaboration and iOS previewing features.

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.
