Firefox 1.x

Firefox is a web browser based on the open source Mozilla web browser. It was intended to be lighter weight and faster than Mozilla, separating the e-mail client in to the new Thunderbird product. At release, it implemented better support for web standards than Microsoft Internet Explorer. Firefox included features such as tabbed browsing and support for add-ons.


Release notes

Firefox 1.0 was released with much grass-roots fanfare. At the time Internet Explorer 6 was showing its age, having turned in to a cesspool for abusive advertising and malware.

Installation instructions

Firefox 1.x support Windows 95/NT and later. Windows 95 requires the DCOM and Winsock2 updates before installing.
