JavaScript debugger reports: Error: redeclaration of const kIOServiceProgID Source File: chrome://communicator/content/utilityOverlay.js Line: 1 This error caused otherwise healthy JavaScript form validation script on the page to be ignored (a form was submitted which should not have been). The form's JavaScript does not declare any constant, let alone one called 'kIOServiceProgID'. FYI, the form's JavaScript validation works in Navigator 4.77, IE 5.5, and Opera 5.12.

Reporter: how old is your build? I thought I remembered this particular error being fixed recently.

if it's seen with 0.9.5 it sounds like a dup of bug 86238 (by way of bug 105767)

Build 2001101117; Mozilla 0.9.5
