> (...) but are different browsers not allowed to be different? Allowed? Sure, why not? Desirable? Hell, no. Think about it. If you are developing a web application and you need ensure it runs on all supported platforms then you either: a) use standard APIs that are provided by all platforms, b) use platform-specific APIs and watch the number of platform-specific tests to grow exponentially along with development and maintenance effort, c) drop platforms. Suffice to say, option a) is far more desirable.
