Firefox holds 2.26% of the global all-device browser market as of April 2026, based on StatCounter data cited by Backlinko. The June 2026 reading came in at 3.33%, a sign the multi-year slide may be leveling off. This post covers Firefox usage statistics for 2026: user counts, share by device, country and regional breakdowns, and how the browser stacks up against Chrome, Safari, and Edge.
Firefox Usage Statistics: Key Numbers
- Firefox recorded 203,426,928 monthly active users on June 22, 2026, per Sci-Tech-Today.
- Desktop share sits at 4.21% to 6.31% globally, while mobile share is 0.64%, a gap of roughly 6.6:1.
- Germany leads all countries at 9.81% Firefox share in June 2026.
- Roughly 86% of Mozilla’s annual revenue comes from its Google search agreement.
- Firefox held about 33% of the market at its 2010 peak, versus 2.26% in April 2026.
The short version: Firefox is now a desktop browser with a small but stable base concentrated in North America and Europe. Its annual decline slowed to about 13% year on year in 2025–2026, per XtendedView, and it remains the only major browser not owned by Apple, Google, or Microsoft.
How Many People Use Firefox in 2026?
Backlinko estimated 138 million Firefox users worldwide in April 2026 based on StatCounter share data. Sci-Tech-Today counted 203.4 million monthly active users by June 22, 2026, using Mozilla’s own telemetry-based measure. The two figures use different methods, which explains the gap.
Global all-device share moved from 3.04% in 2022 to 2.37% in 2025, a drop of 0.67 percentage points over three years, according to StatCounter figures compiled by Yaguara and XtendedView.
| Period | Global All-Device Share |
|---|---|
| 2022 | 3.04% |
| 2024 | 2.18% |
| 2025 | 2.37% |
| April 2026 | 2.26% |
| June 2026 | 3.33% |

The April-to-June swing reflects month-to-month variance in StatCounter’s session-weighted panel rather than a sudden influx of users. Firefox’s peak came around 2010, when about one in three internet users ran the browser, per Backlinko.
Firefox Usage Statistics by Device
Desktop is where Firefox lives. Global desktop share measured 4.21% in April 2026 and 6.31% in June 2026, per XtendedView citing StatCounter. Mobile share was 0.64% in April 2026, per Backlinko.
That works out to a desktop-to-mobile ratio near 6.6:1. Chrome’s ratio is close to 1:1 and Safari skews toward mobile, so no other major browser leans this hard on desktop.
| Segment | Firefox Share | Period |
|---|---|---|
| Desktop (global) | 4.21% | April 2026 |
| Desktop (global) | 6.31% | June 2026 |
| Mobile (global) | 0.64% | April 2026 |
| Mobile (global) | 0.53% | February 2025 |
| US desktop | 5.5% | May 2026 |

Two structural factors cap mobile numbers. On iOS, every browser must use Apple’s WebKit engine, so Firefox on iPhone loses its Gecko engine entirely. On Android, Chrome ships as the default through Google’s distribution deals. The desktop base skews toward developers, Linux users, and privacy-focused users, and Firefox is the default browser on most Linux distributions. Chromebook owners can also add it: Firefox runs on ChromeOS as an Android app, and there is a simpler way to install the full desktop version through the Linux container.
US Desktop Readings Vary Sharply
US desktop share went from 5.5% in May 2026 to 13.96% in June 2026 in StatCounter’s data, per XtendedView and Sci-Tech-Today. StatCounter weights sessions rather than users, so country-level device segments can swing hard in a single month. Treat the 13.96% figure as an outlier reading, not a trend.
Firefox Usage Statistics by Country and Region
North America leads all regions at 7.69% Firefox share in June 2026, per StatCounter data compiled by Sci-Tech-Today. Asia sits at the bottom at 1.17%, a product of mobile-first internet use where Chrome and Samsung Internet dominate Android devices.
| Region | Firefox Share (June 2026) |
|---|---|
| North America | 7.69% |
| Europe | 4.42% |
| Oceania | 2.62% |
| South America | 1.81% |
| Africa | 1.42% |
| Asia | 1.17% |

Germany posts the highest country share at 9.81%. The country has a long institutional preference for open-source software, and several German state governments have backed Firefox deployments over the years. The US measures 9.01% at the country level, Canada 3.39%, the UK 2.16%, and India 0.68%.
Firefox ranks fourth in Europe behind Chrome, Safari, and Edge, and ahead of Samsung Internet and Opera, per XtendedView. American Firefox users spend about 6 hours a day browsing, with Russian users close behind at 5.5 hours, based on Enterprise Apps Today data.
How Does Firefox Compare to Chrome, Safari, and Edge?
Chrome controls 65.1% of the global all-device market in Q1 2026, down 1.9 points year on year, per Digital Applied citing StatCounter. Safari holds 17.04% with about 1.04 billion users, and Edge holds 5.53% with roughly 338 million users, per Backlinko.
| Browser | Global Share | Estimated Users |
|---|---|---|
| Chrome | 65.1% | — |
| Safari | 17.04% | ~1.04 billion |
| Edge | 5.53% | ~338 million |
| Firefox | 2.26% | ~138 million |
| Samsung Internet | 1.95% | — |

Engine share matters as much as browser share here. Blink, the engine behind Chrome and Edge, powers more than 75% of all web sessions globally, per Digital Applied. Gecko, Firefox’s engine, dropped 1.4 points over four years while Blink gained 2.1 points in two. Gecko is now the only major non-Apple, non-Google rendering engine in active use, which is one reason many users keep Firefox installed as an alternative browser even on Chrome-centric devices.
One concrete technical gap: WebGPU remains behind a flag in Firefox in 2026, while Chrome and Edge ship it in stable releases. On CSS support, Firefox matches the field, with Container Queries and the :has() selector both above 96% availability across Tier 1 browsers.
Mozilla Revenue and What Keeps Firefox Users Around
About 86% of Mozilla’s annual revenue comes from its search agreement with Google, per XtendedView. Over 80% of Firefox users keep Google as their primary search engine. Mozilla appointed a new CEO in December 2025 and rolled out optional AI features in late 2025, all of which can be switched off.
| Metric | Figure |
|---|---|
| Google share of Mozilla revenue | ~86% |
| Firefox users on Google search | 80%+ |
| Firefox ESR business users | ~1.8% |
| Current ESR release | 140.12.0 (June 16, 2026) |
| 32-bit Linux support ended | November 2025 (Firefox 145) |

The dependency cuts both ways. Google pays for Firefox’s user base as a search distribution channel, and that negotiating position weakens as share declines. What keeps the remaining base attached is independence, default tracking protection, and deep customization, features that appeal to the same users who tune their browser privacy settings in the first place. Firefox ESR also gives devices past their OS update window a browser that still receives security patches, though ESR accounts for only about 1.8% of business users.
