Here’s a kind of annoying one. If you’re doing development on forms, odds are at some point in time you’re going to want to pre-select a radio button. Doing that is simple:
<input type=”radio” name=”myButton” value=”myValue” selected=”selected”>

So, you add that to a form element, and, like any good developer, you’re using FireFox to test as it’s more accurate rendering engine means you can develop compliant pages. Of course, your radio button remains unchecked. You can refresh as much as you want while tinkering with your code, but it probably won’t ever change. Why? FireFox caches radio button selections basically forever. The only way to get a true look at radio button values is to perform a hard refresh (CTRL+SHIFT+F5 on the PC). Now your box is selected, as it should be.

That’s the Golden Rule for FireFox Form Development: always make sure your cache is clear with CTRL+SHIFT+Refresh.
