Summary: WebKit used to be able to display rtf files directly in the webview. However, it can no longer do this in Safari 3 beta or in WebKit TOT. Steps to Reproduce: (1) Install Safari 3 beta (2) Open Safari (3) Open http://developer.apple.com/textfonts/Fonttools/Index.html (4) Click ReadMe http://developer.apple.com/textfonts/FontToolsDocs/ReadMe.rtf Expected Results: The page http://developer.apple.com/textfonts/FontToolsDocs/ReadMe.rtf displays in Safari. Actual Results: The page http://developer.apple.com/textfonts/FontToolsDocs/ReadMe.rtf is downloaded to the preferred downloads folder. Regression: The problem does not occur in Mac OS X 10.4.10 and earlier using the stock installed WebKit. Support for rtf was dropped in WebKit r14258. Notes: This issue affects all WebKit apps, not just Safari. For example, Vienna http://vienna-rss.sourceforge.net/ has an rtf acknowledgments file that was opened in a browser tab, but with the Safari 3 beta installed, the rtf file is downloaded instead of displayed in the tab. The dropping of rtf support leads to inconsistency, because WebKit can still display plain text (for example, Tutorial examples Summary http://developer.apple.com/textfonts/FontToolsDocs/Tutorial/CommandSummary.txt from the same page as above: http://developer.apple.com/textfonts/Fonttools/Index.html) as well as pdf. 27-Jun-2007 Jeff Johnson: For further reference, see http://bugs.webkit.org/show_bug.cgi?id=10781. 05-Jul-2007: Please know that after considerable internal discussion, this feature has been removed. At this time, we do not anticipate re-adding this feature. A third-party plugin can implement this if needed.
