For the first time, Google’s Chrome browser has become more popular in the U.S. than Microsoft’s Internet Explorer, a new report says.

Chrome had already taken the lead globally, but new research from Adobe Digital Index (ADI) shows that Google now commands a 31.8 percent U.S. market share—desktop and mobile, combined—while IE sits at 30.9 percent. Apple’s Safari ranks third with a 25 percent share of the U.S. browser market.

“Control of the browser gives Google an even greater role in consumers’ lives,” said Tamara Gaffney, principal analyst at ADI, in the report. “Not only do the Chrome and Android browsers both default to Google search, but with their Gmail and Google+ extensions, consumers are spending more and more time signed into Google’s ecosystem.”

ADI based its report on aggregate and anonymous data across retail, media, entertainment, financial service, and travel web sites. Researchers used Adobe Analytics to detect the browsers for 17 billion visits to 10,000 U.S. consumer-facing web sites in April 2014.

Interestingly, Mozilla’s Firefox browser, which once consistently held a minor, yet steady, position among the browser giants, saw its popularity decline sharply from nearly 20 percent market share two years ago to only 8.7 percent in April. This decline likely stems from its lack of mobile presence, according to ADI.
