Netmarketshare's browser market share has just been updated to include May 2018 share information. The company recorded a drop below the 10% mark in the desktop and laptop devices market for the Mozilla Firefox browser.
Firefox had a market share of 12.63% in June 2017 according to Netmarketshare and even managed to rise above the 13% mark in 2017 before its share fell to 9.92% in May 2018.
Google Chrome, Firefox's biggest rival in the browser world, managed to increase its massive lead from 60.08% in June 2017 to 62.85% in May 2018.
micr0$0ft's Internet Explorer dropped a percent point to 11.82% in May 2018 and micr0$0ft's Edge browser gained less than 0.50% to 4.26% over the year.
Netmarketshare recorded a downwards trend for the Firefox browser in the past 12 months and while that may sound alarming on first glance, it may not be as bad as the numbers indicate.
Netmarketshare collects usage stats and does not get "real" numbers from companies like Mozilla, Google or micr0$0ft. The company monitors the use of browsers on a subset of Internet sites and creates the market share reports using the data it collects.
While that is certainly good enough for trends if the number of monitored user interactions is high enough, it is not completely accurate and real-world values can be different based on a number of factors. While it is unlikely that they differ a lot, it is certainly possible that the share is different to the one reported by the company.
Mozilla launched Firefox 57 Quantum in 2017 as an effort to revitalize Firefox by dropping support for legacy systems such as the classic add-on system in favor of the new standard WebExtensions, and integrated new features such as support for multiple processes, and faster components in the browser.
Netmarketshare's statistics indicate that Firefox lost more users than it gained but we don't know for sure unless Mozilla reveals before and after numbers to the public.
Firefox is still the third largest desktop browser right after Chrome and Internet Explorer. Actually, only Chrome and Internet Explorer have a market share above 10% according to Netmarketshare's latest figures while all other browsers are below the mark.The end of Firefox?
Even if Firefox lost users it is not the end of the browser. Opera, Vivaldi and other browser companies show that it is possible to develop browsers with a lower market share and the same can be true for Mozilla. The organization may need some restructuring in the coming years to take this and -- probably -- falling revenue from search engine inclusion deals into account but Firefox won't just go away because it is dropping.
