Browser Security Settings for AJAX Enabled ASP.NET Pages
AJAX functionality in ASP.NET is compatible with most modern browsers. It runs with the default security settings for these browsers.
Browser and Operating System Compatibility
Users can view your AJAX-enabled ASP.NET sites by using most modern browsers. The following lists show compatible browser versions and operating systems.
Supported Browsers
Microsoft Internet Explorer 6.0 or later versions.
Mozilla Firefox version 1.5 or later versions.
Opera version 9.0 or later versions.
Apple Safari version 2.0 or later versions.
Supported Operating Systems
Microsoft Windows XP with Service Pack 2 installed.

Security and Privacy Settings
The following table lists required browser security and privacy settings for both user browsing and site development. In all cases, the recommended settings are the default settings for that browser.
Internet Explorer 6 |
Make sure that the Internet Zone in the Security Zones settings is set to Medium. |
Internet Explorer 7 |
Make sure that the Internet Zone in the Security Zones settings is set to Medium-High. |
FireFox 1.5 or later versions |
In the Tools menu under Options, make sure that Enable JavaScript is selected. |
Opera 9.0 or later versions |
In the Tools menu under Quick preferences, make sure that Enable JavaScript is selected. |
Safari 2.0.4 or later versions |
Click Safari, Preferences, Security, and then Web Content and make sure that Enable JavaScript is selected. |
Note
If browser security and privacy settings are set too high, JavaScript might be disabled. In that case, the browser cannot run the client-side functionality of an AJAX-enabled ASP.NET application. For example, an AJAX-enabled ASP.NET page would display; however a UpdatePanel control on that page would be unable to execute asynchronous postbacks for partial page rendering.
