Now and then, mainly when im creating huge forms I get CF to generate HTML. The process is usually simple
Write code
Switch to browser
Run page
View source
See some formatting issue
Close source view
Go back to editor
Ammend code, then go through steps 2 onwards
But Firefox actually helps your here. Once you have viewed the source you can actually just hit F5 to refresh the view/code. Savin just a little bit of your sanity in the process.
