The answer: Firefox.
You’re probably familiar with the Mozilla Firefox browser from its original release back in 2008.
But you might not know that it’s also one of the most popular browsers in the world.
According to Mozilla, Firefox is used by over two billion users around the world and is used for more than three billion websites.
While most of its usage takes place in the United States, Firefox’s popularity has spread around the globe.
So far, Mozilla has counted over 100 million Firefox users around Europe, the United Kingdom, India, Brazil, China, India and more.
In the past year, Mozilla said it’s seen Firefox usage grow even faster.
The number of active Firefox users has more than doubled from 1.3 billion users in July 2015 to 2.4 billion users today.
Mozilla said its monthly usage grew to a record of 1.7 billion users by the end of June, while Firefox’s overall usage has more then doubled in that same period.
“We are seeing Firefox users grow by more than two billion in the past 12 months and we are confident that this is a trend that will continue,” Mozilla said in a statement.
