You can use Type-X to test your fonts on any website.
The font never leaves your computer and is easily updated when you're still in development. It'll also give you fine-grained control over how exactly it is used on websites.
It's currently only available for Chrome.
Would there be any interest to fund a Firefox or Safari version?
