The discussion centers on Internet Explorer 7 (IE7) and its comparison to Firefox, highlighting the perception that IE7 attempts to mimic Firefox's features. Users express a preference for Firefox, citing its security advantages and better support for web standards. Despite criticisms of IE7 and its predecessors, the necessity of accommodating these browsers in web design is emphasized due to their widespread use. The conversation also underscores the importance of adhering to W3C standards and RFCs in web development, arguing that web design should prioritize cross-browser compatibility to avoid losing visitors. Participants debate the relevance of RFCs in the context of web standards and the historical development of the Internet, with a consensus that open standards should guide web design practices.
