The following describes one of two browsers: Netscape 4 or Internet Explorer 6.
This browser was wildly popular back in its day with a market share of over 70%. Then Microsoft, in order to protect its lucrative Windows monopoly, crushed the life out of it. They got away with it too, despite public outcry. Only critical patches and security fixes are released for this browser anymore. Today, web developers consider it a pain to design for. Other browsers have long since passed it in terms of JavaScript, DOM and CSS support. This browser is now generally considered an outdated mess of quirks and bugs.
Can you guess the browser from the clues given? Neither can I.
