Firefox is a free and open-source web browser developed by the Mozilla Foundation. The browser is available for Windows, macOS, Linux, and Android. Firefox is considered one of the most popular browsers globally, with a global market share of around 10%.
The browser was first released in 2004, and it has undergone several significant updates since then. In 2014, Mozilla announced that it would start using Google as the default search engine for Firefox in the United States. This change caused some controversy, as many people believed it would lead to a decline in Firefox’s popularity. However, Mozilla has continued to invest in Firefox, and it remains one of the most popular browsers today.
