Firefox isn&#x27;t losing market share because of minor performance differences.<p>We live in a world now where the browser that comes with your computer&#x2F;phone&#x2F;tablet is usually good enough for most people. Firefox isn&#x27;t even a consideration anymore, and I say that as someone that uses Firefox as their main browser.<p>Firefox&#x27;s popularity grew when IE was seen as bad even by non-technical users. There&#x27;s not much selling points for the average person to replace their default browser anymore.
