Galeon made use of Gecko's features including configuration options and standards support. Apart from that, Galeon had several features that were uncommon in browsers at that time:
The project was started by Marco Pesenti Gritti with the goal of creating a web browser that would be fast and consistent with the GNOME desktop environment. The first public version (Galeon 0.6) was released in June 2000.
Galeon was widely seen as one of the best Linux browsers available. The polls revealed the substantial usage share of Galeon, though its popularity was regarded as owing to lack of stability evident in Mozilla's browsers.
In November 2002, as the result of several discussions on the topic Gritti made the decision to cease his work in Galeon and fork the project and started development of a HIG-compliant web browser he called Epiphany (now known as Web).
As Gritti no longer controlled the development of Galeon, the previous functionality was restored in subsequent releases and some new features were added, though development got slow after the split. At the same time the rising popularity of Firefox, its status of the default browser in major distribution and the overwhelming number of its extensions led to decline of Galeon's user base.
Eventually the Galeon developers announced plans to halt development of Galeon, saying "the current approach is unsustainable" regarding the resources required to maintain it. Instead, they planned to develop a set of extensions for Epiphany to provide similar functionality.
Even after development ceased in September 2008, the browser remained popular and in December 2011 was still available in some Linux distribution's repositories, such as Debian 6 Squeeze, although it was not part of Debian 7 Wheezy.
Critics noted Galeon's tricky plugin installation.
