           Summary: Filling FedEx forms on Mavericks beach balling,
                    unresponsive
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
               URL: https://discussions.apple.com/thread/5477570?tstart=0
        OS/Version: Mac OS X 10.9
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org

I ship a lot through FedEx and create the shipping labels on their site. Today I updated to Mavericks and Safari 7.0 and the nightly r157388 of Webkit, both beach ball while trying to fill in the Fedex form when creating a shipping label. Changing to Firefox resolves the issue immediately, also just before I instal Mavericks I used the same nightly and was abel to create labels just fine. There is also a discussion for this in apple support, I have included here the link to it. If one reads through the discussion will find out that not only Fedex, but other sites with forms and JavaScript interaction are affected. The problem can be described the following:
All regular pages of Fedex load and are responsive. Once I get to the form for creation of a shipping label, the entire content in the tab freezes. I try to click on a field to type text, or try to click on a drop down menu to select an option, and nothing happens, instead a beach ball comes up and the entire tab is frozen. If one has patience and waits eventually the first operation intended would show, and than beach balling starts again. My take on this is that something must be wrong in the relation between JavaScript, sandboxing of tabs and possibly some security restrictions in Safari 7. But most likely all points to a JavaScrip bug/memory leak/broken loop that slipped into the final Safari 7
