Differences between browsers, such as the window.event that does not work in Firefox

While the window.event was correctly evaluated on Chrome and IE, Firefox gave the error "ReferenceError:Event is not defined".

Window.event does not exist in Firefox. Different browsers have different event models. Firefox handles the events slightly different IE and Chrome and for that reason it has not worked. A work-around is to pass the event as an argument to the function:
<a onclick="testfunction(event);">
 //...
</a>

testfunction(e){
 evt = e || window.event;
 //...
}
or use a library like jQuery to avoid dealing with all the differences between the browsers.

The answer give information why does the problem occur and that helps understanding it. But a little more description what "the function" does would have been very nice to understand the solution easily.
