In reality, the only completely safe way to use a browser hack is to target dead
browsers??”those browsers that are no longer in development, like Internet Explorer
6??”and target them in such a way that you can be sure the hacks you??™re using will
continue to work in that browser.
Don??™t apply hacks to newer browsers, such as Firefox 2, and Opera 9??”they??™re
updated regularly, and new features and bug fixes are addressed relatively quickly.
It??™s just not safe to use a hack for these newer browsers, and usually they don??™t need
it anyway??”even if they do need adjustment, a change of design will often
accommodate any deficiencies you find. Finally, whenever you use a hack, you face
the difficulty of finding one that will work on just the browser you??™re targeting
