Your Browser Probably Lies To The Big Sites (Blame Chrome)

Firefox and Safari sometimes lie about their identity or change rendering behavior when visiting major websites. This happens because Chrome's market dominance leads developers to build sites around Chrome-specific features or quirks, forcing other browsers to implement compatibility fixes to avoid breaking user experience. Firefox exposes these fixes at about:compat, while Safari stores them in a quirks file. The broader issue is that browser engine consolidation means one company effectively controls web standards by default.
