Every time I start any version/build of Firefox 4.0 (release or beta) I receive a JavaScript Application error "TypeError: Components.Classes [TvtPwmComponent_CID] is undefined".  On the same machine I never received this error using Firefox 3x.  Clicking OK bypasses the dialog box and allows Firefox to open.  Once opened it appears to work properly.

Reproducible: Always

Steps to Reproduce:
1.Run Firefox 4.x
2.
3.
Actual Results:  
Same as Details window description above.

Expected Results:  
s/w should run without returning a JavaScript Application error.

Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode

How about with a new, empty profile? http://support.mozilla.com/en-US/kb/Basic+Troubleshooting#Make_a_new_profile

The issue does NOT occur when Firefox starts in Safe Mode.  However, the issue DOES occur with a new profile.

"TvtPwmComponent" isn't in our code. A quick Google indicates it's part of some Lenovo sercurity application extension.

You'd see this with new profiles because they will still load system-installed extensions. Either upgrade the addon or remove it from your system.
