History of the browser user-agent string (2008)
I remember that in the very early days of Firefox, some websites would refuse to serve pages to anything that wasn't Internet Explorer. I did not see the point to that and I was not amused.Firefox didn't have a problem displaying those pages, so I had to install a plugin so that Firefox could pretend to be Internet Explorer so that I could just see the web page.I'm glad those days are over.
