Mozilla Firefox

''This article is about the web browser. For the operating system, see Firefox OS.''

2002–2004
In 2002-2003 the name was "Phoenix" from version 0.1 to 0.5.

In 2003-2004 it was renamed "Mozilla Firebird" from version 0.6 to 0.7.

2017–present
In July 30, 2018 Mozilla announced that Firefox's logo will have a complete change. In the official website, the company shared two “design system approaches” to get feedback from its users. Both options offer a “master brand” that all of the products will live under. Mozilla also shared options for a general browser icon, along with what appear to be other, more singularly focused browser icons.

The decision will be taken in a few months.
