Mozilla is readying a program called “Build Your Own Browser” that’ll allows enterprises to create a customized browser that can be easily installed across multiple corporate desktops. Through the program, which’ll start sometime soon after Firefox 3.5 is released at the end of June, companies can use a Web application provided by Mozilla to specify certain customizations for the browser—such as bookmarks to certain sites or corporate intranets or portals, said Mike Beltzner.
