Below are two pages where Auto-fill does not work with WebKit SVN-r24668 It works fine in regular Safari Version 2.0.4 (419.3). The preferences are the same in both: Auto-fill: Info from Address Book & Other Forms Accept Cookies: Only from sites you navigate to. What should happen: As you type in the stock symbol, you get a drop-down list of Symbols that match Symbols you have previously typed. To reproduce, type in various stock symbols. https://fastquote.fidelity.com/webxpress/popup_order_book.phtml https://fastquote.fidelity.com/webxpress/popup_frameset.phtml
Autofill is a Safari feature, not a WebKit one so the proper place to file this would be at <https://bugreport.apple.com/>. However, you say you're using Safari 2 and the nightlies are incompatible with Safari 2's autofill. Try upgrading to the Safari 3 beta, which fixed compatibility with autofill and the nightlies and see if this still happens. If it does, please file a bug at the URL above. Either way, this bug is invalid for here.
