Do Not Disturb is designed to be used in scripted and server environments where no person is present to answer prompts and close popup windows.  For example, Do Not Disturb works well with "headless" Linux server applications that use Firefox in conjunction with a virtual framebuffer such as Xvfb.

Do Not Disturb features include:

• Suppresses alert() and other JavaScript prompts that web pages use.
• Automatically cancels disruptive browser dialogs such as the "What would you like to do with this file?" window that is shown when Firefox starts to download a file.
• Suppresses certificate warning prompts that are normally shown when a web site has an expired or invalid certificate.
• Prevents web pages from using the window.print() JavaScript function.
• Prevents web pages from opening any new windows or tabs.
• Allows you to control which items are blocked from the Do Not Disturb Options window (accessible from the Firefox Tools menu).
• Works well with Pearl Crescent Page Saver Pro and Page Saver Toolkit.

If there are other features you would like to see added to the Do Not Disturb, please let us know.
