Safari 4? Firefox?
The current release only supports Safari 3.1. Firefox for Mac and the Safari 4 beta will not work. I did try setting the user agent to Safari 3.2.1 using the Develop menu in the Safari 4 beta, and everything seems to work, but Intuit will not support this configuration. Make sure you uninstall the Safari 4 beta, or just live with any potential quirks when setting the user-agent to a different value.
