I love a good trip down tech memory lane. This one doesn’t to back too far, just 20 years to 2002. Firefox (originally Phoenix) came at the tail in the browser wars. Internet Explorer had pretty much won. Mozilla split out the browser from the bulky Netscape Communicator suite. It was truly a community project to make a smaller nimble fast browser. I recall installing Firefox on computer lab machines where I was working at the time and being excited with each new version. There were a lot of changes coming pretty quickly at that time, including the introduction of the tabbed browser window. This site popped up recently documenting the history of the UI/UX for Firefox as it evolved.
