When in Web Security and the operation mode is set to Transparent Authentication (and I used the local database for user authentication), and I go to google.com with FireFox 3.0.10, I get the authentication page and can fill in my credentials but the page(s) are not loaded. It "hangs" on If I try another page -> same results.
When I use IE 8, I also get the authentication page and fill in my credentials, I get a nice pop-up that shows a timer [;)] and I go directly to the desired page...
