Flash has also been used to circumvent some of the browser protections, especially for older browsers. For example it has been the way to achieve cross-origin http requests (CORS) for browsers that don't support it, like IExplorer < 9 (or 8?) and even IExplorer 9 because the CORS support is shit for that one. On one hand it's been cool for developers to be able to do such things, but on the other hand it makes your browser less secure. Anyway, I'm a Firefox user and I don't have Flash installed. The web works just fine without it. One less plugin to worry about.
