Firefox market share drops to 2.19% as Chrome dominates with over 70%

Firefox global share hits 2.19% while Chrome surpasses 70%

Firefox is in a slump. This isn't just bar-room speculation; it reflects the global usage figures tracked by the industry. In September 2024, Mozilla's browser held a **2.74% global share** compared to **Chrome's 65.18%**. By May 2026, the situation had worsened considerably: **2.19% versus 70.03%**. On desktop, where Firefox still had some ground to defend, the collapse is even starker: dropping from **6.56% to 3.79%** in the same period, while Chrome rose from 64.88% to 75.05%.

The debate over the fox's decline has been ongoing for nearly two years, shifting from technical complaints to harsh assessments. A long-time defender summed it up bluntly: "As of today, Firefox has one less user, and that's me." The reason, they argue, isn't performance but security: Chromium is more secure by default and allows for additional hardening, albeit at the cost of estimulante ilegal in benchmarks.

The technical argument: a 1 GB, 2 GHz machine

The analysis began with a home test: a virtual machine with less than 1 GB of RAM and a processor capped at 2 GHz, where Chromium navigated more smoothly than Firefox due to lower memory consumption and a faster JavaScript engine. The conclusion is uncomfortable for Mozilla: on modest hardware, the browser that prides itself on lightness loses the comparison.

The most common counter-argument is that this scenario doesn't represent the real user. A machine with those specs is a relic today, and measuring a 2026 browser on fifteen-year-old hardware says little. However, the underlying data—that Chromium scales better on constrained machines—cannot be dismissed with sarcasm.

uBlock Origin, the last stronghold

If anything keeps Firefox in the conversation, it's ad blocking. The uBlock Origin extension works perfectly in Firefox; in Chromium-based browsers, blocking is limited to uBlock Lite and similar tools, due to the extension architecture imposed by Google's ecosystem. For users who rely on blockers as a daily navigation tool, this is the decisive factor.

Some note that the attack surface grows with each installed extension and that uBlock should be the only one. Others recall that Firefox allows syncing passwords via its own servers, something Chrome does too but its derivatives often lack by default.

Wear and tear is not just technical

Internal criticism points to management. Mozilla is accused of diverting resources to side projects—Pocket, the Rust language—while the browser lost compatibility against websites designed for Chrome. The departure of Brendan Eich, co-founder and creator of JavaScript, due to his stance on same-sens marriage, is still cited nearly a decade later as a symptom of leadership focused on agenda rather than product.

Money doesn't help the narrative either: Mozilla depends on payments from Google to remain the default search engine, a dependency seen as a mortgage on its independence. Added to this are controversies over new terms of use, which require accepting a license agreement to install the executable version.

Compatibility, the most painful front

Average users don't switch browsers for ideology. They switch because a website won't load. Testimonials of failures in government portals, banks, and services like Wallapop are repeated: certificate warnings blocking access, broken page sections, or the need to open another browser to complete a task. ESR versions, designed for stability, aren't spared either: they become outdated and cause compatibility issues with modern sites.

The integrated translator, a flagship antiestéticature, also takes hits: it translates in bursts, forcing users to wait during scrolling. On a device with a third-generation i5 and 12 GB of RAM, performance degraded starting with version 140.

Who stays and why

A hardcore core remains unmoved. Users of Firefox since version 2 in 2006 see no reason to change. And there is a trend migrating to derivatives: LibreWolf, Zen, Brave, Vivaldi, Opera. On Android, Firefox maintains a real advantage: it supports all desktop add-ons, including full uBlock and extensions to bypass paywalls, something Chrome doesn't even allow on desktop.

The cautious prediction: Firefox won't disappear, sustained by Google's money and its role as an antitrust counterweight. But it will continue losing share as long as the web is written for its competitor's engine. The fox isn't dead. It's in intensive care, and the family is arguing about who pays the bill.
