I will work on getting a regression window now.

Comment 2

I neglected to notice that the profile where I get the crash has several extensions installed - when I try to reproduce this using a clean trunk profile I am not able to get the crash. I will try to determine which extension may be the culprit.

I also get this error in the console:

Error: uncaught exception: [Exception... "Component returned failure code: 0x80570018 (NS_ERROR_XPC_BAD_IID) [nsIJSCID.getService]"  nsresult: "0x80570018 (NS_ERROR_XPC_BAD_IID)"  location: "JS frame :: chrome://fdm_ffext/content/fdm_ffpxy.js :: <TOP_LEVEL> :: line 1"  data: no]

Enabled Extensions:     
Microsoft .NET Framework Assistant
RealPlayer Browser Record Plugin
Search Helper Extension (part of Bing Toolbar which is disabled)
Weave Sync
Nightly Tester Tools
Free Download Manager plugin
NoScript

Unfortunately I have not made much traction in figuring out which extension might be causing this issue. I systematically disabled all extensions including .NET and I am still able to repro the crash 100%. by simply loading the site in the URL.

Will test on my Win 7 lab machine with the same extensions to see if I get the same result.
