    Firefox Extension Developer

    United States - Last active: 08/01/2014 - Tests: 1 - Portfolio: 3

    I've been developing and customizing web browsers since 1996. In my 15+ years at IBM, I was a developer or team lead for OS/2 based browsers, including Netscape Navigator, IBM Web Browser and Firefox. During my time at IBM, I also focused on making the enterprise deployment of Firefox easier, which included developing the CCK Wizard Firefox extension which helps enterprises customize Firefox. The CCK Wizard is used by a number of large companies, including IBM. Other extensions I've developed include Operator which enables microformats inside of Firefox and IE8 Activities which is an implementation of the IE8 Accelerators functionality for Firefox. After leaving IBM, I founded Kaply Consulting. Kaply Consulting specializes in customizing Firefox and has helped various clients, including companies like Brand Thunder, customize Firefox to meet their needs. They’ve also assisted companies like SurfEasy in customizing Firefox. I can help with customizing or deploying Firefox, or creating Firefox extensions.
